Hello, I am looking for paleoclimate data in order to perform species distribution models, however in the WorldClime database there is no 30 sec spatial resolution available for the Last Glacial Maximum. Is it possible to use the 30 sec resolution from WorldClime for the Mid Holocene and Last inter-glacial, and 30 sec for the Last Glacial Maximum from another database? If not, what other database would you suggest? Thank you.
Hello Georgia,
you can use the rasters from other databases, however, you should check whether the values in each raster are in the same units as for current dataset (in some databases temperature is in Kelvin or values are multiplicated by ten or more). If some raster is in wrong units, it should be recalculated first (for example using QGIS software). For paleo data tou can use PaleoClim database (there is also dataset with current climate):

you could also use CHELSA database where you have 30 arcsec rasters in 100-yeartime steps for the last 21,000 years:
