The following is a list of relevant historic timeseries relating to surface pressure, SST (calculated using the HadISST dataset) and other climate variables. We will try to keep them updated though not all are updated at the source. More timeseries may be added in the future. Click on the Analyze/Plot button to visualize the different timeseries. Click on a description to get timeseries and download information.
