If you want to download the files in floating point accuracy or bulk download via wget scripts, you can also access the files on our file server:

Datasets are either available in full floating point accuracy (float) or reduced to 2 bit integers (integer) recommended for users which do not need the full floating point accuracy.

temp = monthly mean of daily mean temperature [°C(float),°C*10(integer)]
tmax = monthly mean of daily maximum temperature [°C(float),°C*10(integer)]
tmin = monthly mean of daily minimum temperature [°C(float),°C*10(integer)]
prec = monthly precipitation sums [mm]

Monthly data

For now separate layers for each month from 1979-2013 for precipitation and temperature are available on request only as the dataset is quite large.
