When C-LSAT2.0 is reconstructed, the selection of different parameters will lead to specific uncertainties. We used different parameter settings(Table1) during reconstruction, with a total of 756 ensemble members. Among them, the operational options use the intermediate values of various parameters (so-called “optimal” parameters). The dataset reconstructed with the operational optimal parameters is the basis for our daily product evaluation and scientific applications.

If you want to use the data with the operational optimal parameters, you can download the NetCDF files.

reconstructed_CLSAT2.0_tavg.nc

reconstructed_CLSAT2.0_tmin.nc

If you are interested in the data with other parameters, you can download the compression files. Because the data is too large, we split the data into several parts to upload. You’d better download them all and decompress them together.

reconstructed_CLSAT2.0_tavg_ice is the average land surface temperature with maximun ice surface area added.

And the reconstructed_CLSAT2.0_tmax and reconstructed_CLSAT2.0_tmin are the maximum temperature and minimum temperature respectively.

When you decompress the dataset, you'll find :

a) There are seven folders and they represent the data from seven kinds of EOTs training periods and spatial scales.

b) The NetCDF files in the folders are named:masked_reSAT_αyr_βminyrfilter_γcrit.nc

c) If you read the NetCDF files, you will find there are three sets of data in one NetCDF file: masked_reSAT, masked_reSAT2 and masked_reSAT3.

The meaning of them are as follow：
