News
02-may-2012	Added EN3 ocean heat content and salinity content.
25-apr-2012	Updated the Google Earth overlay output routine for even prettier pictures.
25-apr-2012	The RPS routine in the verification section was off by a factor two up to now (thanks Eida)

• The climate of the Netherlands in relationship to global warming (IPCC, KvK)
• Predictability of extreme weather in monthly, seasonal and climate forecasts
• Verification of monthly, seasonal, decadal and climate forecasts (THOR)

A tool I developed for these projects is the KNMI Climate Explorer, which allows anyone to correlate station data, climate indices, observations, reanalysis fields, past seasonal and decadal forecasts and climate change experiments.
