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 byte 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 or K/10 (integer)]
- tmax = monthly mean of daily maximum temperature [°C(float),°C/10 or K/10 (integer)]
- tmin = monthly mean of daily minimum temperature [°C(float),°C/10 or K/10 (integer)]
- prec = monthly precipitation sums [mm]
The integer versions of temperature grids are stored in tenths of Kelvins or tenths of °C. Because tenths of Kelvins are calculated by multiplying a value in Kelvin by 10 (likewise for Celsius), you may have seen the same units erroneously referred to as °C*10 and K*10 (e.g. on worldclim.org).
