Reanalysis Datasets at PSL

PSL maintains a collection of reanalysis datasets for use in climate diagnostics and attribution. Reanalysis datasets are created by assimilating ("inputting") climate observations using the same climate model throughout the entire reanalysis period in order to reduce the affects of modeling changes on climate statistics. Observations are from many different sources including ships, satellites, ground stations, RAOBS, and radar. Currently, PSL makes available these reanalysis datasets to the public in our standard netCDF format:

Many of these datasets can be subsetted, plotted and analyzed by our various web based tools.
