Hi,
I've been using DIVA to make up some bioclim variables for future climate scenarios, and it works really well.
I do have one concern though. When I get to the stage of making the .clm file all the input asciis (prec, tmin, tmax) are uniform with the no_data value = -9999. Once the climate information is extracted from them the scale of the data rage appears to change for the output bioclim .grd / .gri. When exported to ESRI ascii, some are nodata= 0, some are -999.somethin and others are -25037 (or something like that).
Now, every data set i produce with DIVA gives me the same range for a particular variable. so comparing DIVA-made bioclim with DIVA-made bioclim layers works fine. I can build models and project.
