Some PSD datasets and products are not up-to-date due to a system problem. We are working on a fix.
 

3/6 Hourly 20thC V2 Reanalysis Data Composites

We have transitioned the data files from netCDF3 to netCDF4-classic format. As a result, the files are compressed instead of being packed with a scale and offset. As with any netCDF4 file, the user interface will perform the uncompression. We expect the files to be read faster, depending on the application you are using. Please let us know if you run into any issues.


Plot maps or composites of variables from the 20th Century Reanalysis(V2) dataset. Data is available from Jan 1871 to 2012
