Welcome, anonymous user

The KNMI Climate Explorer is a tool to investigate the climate. Start by selecting a class of climate data from the right-hand menu. After you have selected the time series or fields of interest, you will be able to investigate it, correlate it to other data, and generate derived data from it.

Some restrictions are in force: the site does not remember how you filled out the forms, you cannot define your own indices, nor upload data into the Climate Explorer or handle large datasets. If you want to use these features please log in or register.

23-nov-2020Added the global EUMETSAT CM-SAF cloud fraction field 1982-2019, monthly only for the time being.
31-oct-2020Updated GPM/IMERG to V06. The good news is that it goes back to 2000 now, the bad news is that it took 10 days to download those 20 years.
14-oct-2020Recovering from a disk crash on my KNMI computer. Some data may be corrupted, please report problems.
08-oct-2020E-OBS monthly data were shifted to 1950-2049 the last week... Fixed.
05-oct-2020Added 20CRv3 slp and z500 fields extended to the present with ERA5 / ECMWF analyses. Correlations are very good for slp on the overlap period outside the tropics (r~0.95) and good in the tropics (r~0.9 in most areas).
01-oct-2020Found an error in E-OBS precipitation, which was shifted by 4 days after 26-jan-2020.
