Sea-Level Pressure

AOMIP winds are to be derived from sea-level pressure data. The sea-level pressure data set is that originating from the NCEP/NCAR reanalysis and archived at the Climate Diagnostics Center (CDC) of NOAA-CIRES. This data is daily mean. To ensure all AOMIP participants utilize exactly the same data sets, the CDC sea-level pressure data has been copied to the AOMIP website to be uniformly retrieved by AOMIP participants.
