This downtime is expected to last several hours as we work to upgrade our existing Globus Alternate Identity service to an OpenID Connect (OIDC) server running in Globus Connect Server version 5. During the downtime, users will still be able to request and access Globus shares from NCAR RDA endpoints, but will not be able to log into Globus with NCAR RDA identity credentials. We will send out another announcement once the service is restored. Thanks for your patience during this maintenance outage.Thomas Cramhttp://www.blogger.com/profile/00304509187635698731noreply@blogger.com0tag:blogger.com,1999:blog-8431280378972900538.post-85926096688093263742023-01-19T16:09:00.001-07:002023-01-19T16:09:29.013-07:00New RDA website launching next Tuesday, Jan 24<p>The NCAR Research Data Archive is launching a new, redesigned website next Tuesday, Jan 24 that will provide a more modern, simplified, and improved user experience. The new site is more accessible and mobile-friendly, thus users will be able to browse and use most features of the site from a mobile phone or tablet. All of our data access, download, search, and discoverability features will remain as they are on the current website.

been conducted by ECMWF (European Centre for Medium-Range Weather Forecasts) and JMA (Japan
Meteorological Agency). The most recent reanalyses released by these programs are ERA5 (from ECMWF,
spanning 1950 to the current time), and JRA-55 (from JMA, spanning 1958 to the current time). In addition,
ECMWF produces near real-time ultra high resolution operational atmospheric forecasts that are an important
complement to ERA5.</p>
<p>In a collaborative effort within CISL ISD, DECS (the Data Engineering and Curation Section), downloads, processes,
archives, and provides web-based access and services for ERA5, JRA-55, and ECMWF operational forecast data to
a wide cross-section of users and organizations located worldwide. In an ongoing effort to improve the generality
and usability of these datasets, processing by DECS personnel using CISL HPC resources include quality control,
regridding to standardized lat-lon grids, restructuring incoming data into single-parameter time series, and in
the case of ECMWF data, conversion of GRIB format to CF-conforming compressed netCDF4-HDF5 files. In
addition, extensive logistical support and scientific consulting is provided via several platforms, including
the <a href="https://ithelp.ucar.edu/plugins/servlet/desk/site/rda">NCAR Research Data Archive (RDA) Helpdesk
</a></p>
<p>These efforts support a broad range of climate diagnostics, model development and validation, and
intercomparison projects to name a few. The ERA5, JRA-55, and ECMWF operational forecast data is organized
into 17 datasets within the <a href="https://rda.ucar.edu">Research Data Archive</a> which is managed by DECS. The
total volume of these datasets is 2 PB, <font color="red"><i>all of which is stored on the CISL GLADE shared file
system</i></font>. Metrics for web-access alone over the last 15 months indicate that 3600 users have downloaded
2.7 PB of RDA ERA5, JRA-55, and ECMWF operational forecast data. We encourage CISL HPC users to explore this
archive via the RDA website, and especially to take advantage of the availability on GLADE. Three RDA datasets
in particular are good entry points to begin your investigations:</p>
<ul>
<li><a href="https://rda.ucar.edu/datasets/ds633.0">ERA5 Reanalysis (0.25 Degree Latitude-Longitude Grid</a></li>
<li>GLADE root: /gpfs/fs1/collections/rda/data/ds633.0</li>
</ul>

</ul>
<p>HPC users will find that the above links provide more detailed listings of GRIB and netCDF4-HDF5 files located on
GLADE, supporting metadata, documentation, and cross references to related RDA ERA5 and JRA-55 datasets including
monthly means and variances, back extensions of ERA5 data to 1950, JRA-55 near real-time data, and supplementary
and derived products. We endeavor that this serves the HPC community well and in many capacities.</p>Dave Stepaniakhttp://www.blogger.com/profile/12636541420223477171noreply@blogger.com0tag:blogger.com,1999:blog-8431280378972900538.post-66049919051422335302021-07-19T11:06:00.000-06:002021-07-19T11:06:27.304-06:00RDA services unavailable July 25 - 29, 2021<p><span style="background-color: white; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15.4px;">Due to scheduled maintenance on the HPC systems at NCAR, all RDA data access services, including downloads, data subsetting, and THREDDS data server access, will be unavailable July 25–29, 2021.

<p>The ERA5 single level forecast fields, 1978-12 as obtained from the ECMWF Climate Data Store (CDS)
are incomplete -— they do not form a continuous time series with 1979 onward because 6 forecast hours
have been omitted. This is particularly true for fluxes defined by mean rates which includes
for example precipitation products. The four affected groups in the RDA dataset
<a href="https://rda.ucar.edu/datasets/ds633.4/">ds633.4, ERA5 back extension 1950-1978 (Preliminary version)</a>
are:</p>
<ul>
<li>ERA5 atmospheric surface forecast (accumulated), 1978-12</li>
<li>ERA5 atmospheric surface forecast (instantaneous), 1978-12</li>
<li>ERA5 atmospheric surface forecast (mean rates or fluxes), 1978-12</li>
<li>ERA5 atmospheric surface forecast (minimum-maximum), 1978-12</li>
</ul>
<p>NCAR's CISL/DECS has brought this to the attention of ECMWF, and are waiting for ECMWF to fill
in the gap on the CDS. Apologies for the inconvenience, and thank you for your patience.</p>
<p>A more detailed discussion follows:</p>
<p>The ERA5 forecast data 'time' conventions are somewhat awkward (but entirely the prerogative of ECMWF
and especially the Copernicus Climate Data Store -- CDS). For any given day, CDS provides 2 forecast initial times,
06 and 18Z. For each forecast there are 12 forecast hours, 1,2,3,4,5,6,7,8,9,10,11, and 12 hours. In the
netCDF files as produced by CISL/DECS for the RDA, this is represented with two coordinate dimensions,</p>
<p>forecast_initial_time</p>
<p>forecast_hour</p>
<p>The valid time of the forecast data is then</p>
<p>forecast_initial_time + forecast_hour</p>
<p>A discrete 24 hour time series of, for example, "mean rates or fluxes" forecast data (including "Mean total precipitation rate",
kg m**-2 s**-1) in this case is given by</p>
<br>
<table>
<tr><td>06Z forecast initial time current day + 1hr</td><td>(a mean flux/rate between 6 and 7 hr of current day)</td></tr>

</table>
<br>
<p>The crux of the matter is, for 31 December 1978, 1978-12-31, the CDS has omitted the last 6 entries,</p>
<br>
<table>
<tr><td>18Z forecast initial time 1978-12-31 + 7hr</td><td>(a mean flux/rate between 0 and 1 hr of 1979-01-01)</td></tr>
<tr><td>18Z forecast initial time 1978-12-31 + 8hr</td><td>(a mean flux/rate between 1 and 2 hr of 1979-01-01)</td></tr>
<tr><td>18Z forecast initial time 1978-12-31 + 9hr</td><td>(a mean flux/rate between 2 and 3 hr of 1979-01-01)</td></tr>
<tr><td>18Z forecast initial time 1978-12-31 + 10hr</td><td>(a mean flux/rate between 3 and 4 hr of 1979-01-01)</td></tr>
<tr><td>18Z forecast initial time 1978-12-31 + 11hr</td><td>(a mean flux/rate between 4 and 5 hr of 1979-01-01)</td></tr>
<tr><td>18Z forecast initial time 1978-12-31 + 12hr</td><td>(a mean flux/rate between 5 and 6 hr of 1979-01-01)</td></tr>
</table>
<br>
<p>which prevents CISL/DECS from forming an uninterrupted time series with ERA5 data for 1 January 1979,
1979-01-01, because the first entry for 1979-01-01, *as provided by CDS*, is</p>
<br>
<table>
<tr><td>06Z forecast initial 1979-01-01 + 1hr</td><td>(a mean flux/rate between 6 and 7 hr of 1979-01-01)</td></tr>

<p>Although in many other respects the quality of this dataset is quite satisfactory, the current back extension appears to suffer from tropical cyclones that are sometimes unrealistically intense. This is in contrast with the ERA5 product from 1979 onwards (also available from the CDS and
RDA-<a href="https://rda.ucar.edu/datasets/ds633.0/">ds633.0</a>). For more details see the article,
<a href="https://confluence.ecmwf.int/display/CKB/ERA5+back+extension+1950-1978+(Preliminary+version):+tropical+cyclones+are+too+intense">ERA5 back extension 1950-1978 (Preliminary version): tropical cyclones are too intense</a>.</p>
<p>For this reason the current release of the back extension is preliminary.</p>
<p>It is therefore available from separate CDS catalogue entries (hourly, monthly, single level and pressure levels), and <b>RDA dataset ds633.4</b>
<a href="https://rda.ucar.edu/datasets/ds633.4/">ERA5 back extension 1950-1978 (Preliminary version)</a>. Around the end of 2021 an updated version of the back extension is to be made available which will be added to the ERA5 catalogue entries that currently reach back to 1979. After an overlap period (the duration of which is not yet decided), the preliminary back extension will be deprecated.</p>
<p>The full back extension preliminary dataset is expected to be made available near the end of 2020/early 2021.</p>Dave Stepaniakhttp://www.blogger.com/profile/12636541420223477171noreply@blogger.com0tag:blogger.com,1999:blog-8431280378972900538.post-54790901857566129162020-10-22T14:18:00.003-06:002020-10-22T14:25:23.003-06:00Service Level Expectations for RDA Subset Request Processing<p>Due to resource constraints, it may take up to 48 hours for an RDA subset/format conversion request to process to completion.

For 3-hourly and 6-hourly analysis and forecast data that is auto-updated daily please see ds628.8</p>
<p>
<a href="https://rda.ucar.edu/datasets/ds628.8/">JRA-55: Japanese 55-year Reanalysis, Near Real-Time Data</a>
</p>
<p>The analysis data has 2 day delay, the forecast data 2 or 3 day delay depending on group.</p>
<p>For monthly mean analysis and forecast data please see ds628.9</p>
<p>
<a href="https://rda.ucar.edu/datasets/ds628.9/">JRA-55: Japanese 55-year Reanalysis, Near Real-Time Data -- Monthly Means and Variances</a>
</p>
<p>The monthly mean data for a given month is updated within the first few days of the following month.
Both of these datasets represent rotating non-permanent archives. The lifetime of the 3-hourly and 6-hourly data is 7 months. The lifetime of the monthly mean data is to be determined. However, all near real-time JRA55 data is archived into their "formal" counterparts ds628.0:</p>

As far as we know, ECMWF will not be making ERA5.1 available to the general public via the Copernicus Climate Data Store (CDS). Please refer to</p>
<p><a href="https://rda.ucar.edu/datasets/ds633.2/">ERA5.1: Corrections to ERA5 Stratospheric Temperature 2000-2006</a></p>
<p>and especially the 2020 memo by Adrian Simmons and ECMWF colleagues quoted here:</p>
<p>In ECMWF Technical Memo 859 released in January 2020, Simmons and his coauthors report that "<i>the ERA5 analyses of lower stratospheric temperature exhibit a pronounced cold bias for the years 2000 to 2006. This is due to specifying background error covariances for the data assimilation that were inappropriate prior to availability during 2006 of GNSS radio occultation data in sufficient numbers to constrain a cold bias of the assimilating ERA5 model. A new set of analyses, termed ERA5.1, has thus been produced for the period from 2000 to 2006 using the background error covariances that were used to produce the ERA5 analyses for the years 1979 to 1999. ERA5.1 also includes the more restrictive ensemble assimilation of SBUV ozone data that was used in production of ERA5 for 1979 to 1999.</i>"</p>
<p>"<i>ERA5.1 provides analyses with better global-mean temperatures in the stratosphere and uppermost troposphere than provided by ERA5. ERA5.1 stands up well in comparison with ERA-Interim and other reanalyses in the lower stratosphere, although there are also lower-stratospheric temperature differences between ERA5 and other reanalyses in the 1980s and 1990s. These are due in part to differences in radiosonde temperature bias adjustment. The pronounced near-tropopause cold bias of ERA5 from 2000 to 2006 has implications for the representation of stratospheric humidity, for which ERA5.1 performs better, though by no means perfectly. ERA5.1 does not exhibit the spuriously high values of ozone that occur close to the South Pole in the polar nights of 2003 and 2004 in the ERA5 analyses. Synoptic evolution in the extratropical stratosphere is seen to be very similar in two cases involving splitting of the stratospheric polar vortex and secondary vortex formation by dynamical instability. The ERA5.1 representation of the QBO agrees slightly better with radiosonde wind data than that of ERA5. The dataset formed by merging ERA5.1 with ERA5 is generally more homogeneous over time than ERA5 alone. It nevertheless is problematic for global-mean upper stratospheric temperature for all but the most recent ten or so years.</i>"<p>
<p>"<i>ERA5.1 is very close to ERA5 in the lower and middle troposphere.</i>"</p>

This service is recommended for users who are interested in a local region and time period of interest without resorting to downloading a large volume of data files from the ISPDv4 archive.<br />
<br />
To request a subset, go to the ds132.2 <a href="https://rda.ucar.edu/datasets/ds132.2/#!access">Data Access tab</a>, then select "Get a subset". Enter your time period and region of interest, then follow the instructions to submit your data request. After submitting your request, the request will be processed on the NCAR computing system and we will send you an email notification with a download link when your data are ready.<br />
<br />
Users can also browse an interactive map displaying ISPDv4 observation locations by using the <a href="https://rda.ucar.edu/datasets/ds132.2/index.html#wstationViewer" target="_blank">Interactive Station Viewer</a> tool. Filters can be applied to display observation locations by time period, location, and observation type.Thomas Cramhttp://www.blogger.com/profile/00304509187635698731noreply@blogger.com0tag:blogger.com,1999:blog-8431280378972900538.post-55485021091539900132020-03-04T08:02:00.000-07:002020-03-04T08:02:15.780-07:00ERA5 Modes of Interannual Variability<p><a href="https://rda.ucar.edu/datasets/ds633.3/">ds633.3: ERA5 Modes of Interannual Variability</a></p>
<p>represents a suite of climate diagnostics for 56 variables relating to the interannual variability of ECMWF ERA5 monthly mean data. Basic fields for each variable include a monthly mean climatology and standard deviation, corresponding anomalies spanning 40 or more years of data, empirical orthogonal functions (EOFs), principal component (PC) time series, percent variance explained by each EOF, and an estimate of the standard error of the percent variance explained. Dominant modes of variability include El Nino Southern Oscillation (ENSO) in sea surface temperature, and the Antarctic Oscillation (AO) and North Atlantic Oscillation (NAO) in surface pressure. Separate analyses are performed for the entire globe, northern hemisphere only, and southern hemisphere only. There is sufficient information to further explore lagged correlations, teleconnections, and more advanced statistical techniques. Preparation and calculation of this dataset is performed by CISL DECS at NCAR. Code used for computing EOFs of scalar fields can be found at</p>

RDA External Application API Update</h1>
<div>
<br /></div>
The RDA has introduced an update to the RDA External Applications API.
The REST API will now return JSON encoded responses to queries, which should improve interactivity and allow for more robust error handling.<br />
<br />
In addition to the updated HTTPS responses, an updated version of the rdams-client.py script has been released.
This new python client can be used as a command line tool (as in the past) or as an imported python module to interact with the response objects directly.<br />
<br />
A Jupyter Notebook that outlines how to use the module programmatically can be found here:<br />
<br />
<a href="https://github.com/NCAR/rda-apps-clients/blob/master/src/python/rdams_client_example.ipynb">https://github.com/NCAR/rda-apps-clients/blob/master/src/python/rdams_client_example.ipynb</a><br />
<br />
<br />
The complete API documentation can be found here: <a href="https://github.com/NCAR/rda-apps-clients/blob/master/docs/README.md">REST API and JSON Responses documentation</a><br />
<br />
<br />
To demonstrate just one use case,<br />
