Each reanalyses has its strengths and weaknesses. To better select the optimal dataset for your research, it's helpful to take several datasets out for a test spin.
I put our newest reanalysis dataset, the NOAA/CIRES Twentieth Century Global Reanalysis Version 2c, and a timely topic, Atmospheric Rivers (ARs), together into a data exploration exercise by visualizing a strong AR event from Dec 2004 to Jan 2005.

The atmospheric river that caused the Los Angeles flood of 1938
At least one person asked why I used a reanalysis that does not assimilate satellite water vapor data to study an atmospheric river (AR) event.
That's a good question because the NOAA/CIRES Twentieth Century Global Reanalysis Version 2c (20thCR V2c) only ingests three things: surface pressure, sea ice coverage and sea surface temperature. The rest of the analysis is generated by the physical models of NOAA's Global Forecast System (GFS).
