Timeseries

The CHELSA timeseries data is a monthly dataset of precipitation, maximum-, minimum-, and mean temperatures at 30 arc sec resolution for the earths land surface areas. There are separate files for each month starting January 1979 – December 2013. For temperatures also air temperature over the oceans is included.

If you are interested in the performance of the timeseries in comparison to other climate products, check out Table 2 , Table 4 , Figure 3 , and Figure 6 in the publication describing CHELSA in Scientific Data.

 

The coding of the files is as follows:

For temperature:

CHELSA_[var]_[month]_[year].7z

For precipitation:

CHELSA_[var]_[month]_[year]_land.7z

The whole dataset is quite large, please consider this before downloading. We do not have a sub setting tool available yet, so if you need a specific geographic area, you still have to download the whole global layers.
