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.

14-apr-2021The KNMI Climate Explorer was unvailable for a while due to a full hard disk. Again.
14-apr-2021Added an option to put the legend on the left in return time plots (thanks Sihan).
08-apr-2021The KNMI Climate Explorer won the 2021 EMS Technology Achievement Award.
24-mar-2021The expired certificate problem has been solved and the Climate Explorer is running again with a valid certificate. I hope next year I (or someone else) will remember to replace it in time.
23-mar-2021Added HadISST2 sea ice. SST is still not available (thanks Chris).
22-mar-2021Something went wrong trying to install new certificates so the Climate Explorer was unreachable for a few minutes his afternoon.
