JRA-55: Japanese 55-year Reanalysis, Near Real-Time Data -- Monthly Means and Variances
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.
