20th Century Reanalysis Daily 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 daily composites (averages) of the mean or anomalies (mean - total mean) of variables from the 20th Century Reanalysis reanalysis and other datasets. 20th century reanalysis data is available from Jan 1871 to Dec 2012.
