oggm.tasks.process_dummy_cru_file(gdir, sigma_temp=2, sigma_prcp=0.5, seed=None, y0=None, y1=None, output_filesuffix=None)[source]#

Create a simple baseline climate file for this glacier - for testing!

This simply reproduces the climatology with a little randomness in it.

TODO: extend the functionality by allowing a monthly varying sigma

Parameters
gdirGlacierDirectory

the glacier directory

sigma_tempfloat

the standard deviation of the random timeseries (set to 0 for constant ts)

sigma_prcpfloat

the standard deviation of the random timeseries (set to 0 for constant ts)

seedint

the RandomState seed

y0int

the starting year of the timeseries to write. The default is to take the entire time period available in the file, but with this kwarg you can shorten it (to save space or to crop bad data)

y1int

the starting year of the timeseries to write. The default is to take the entire time period available in the file, but with this kwarg you can shorten it (to save space or to crop bad data)

output_filesuffixstr

this add a suffix to the output file (useful to avoid overwriting previous experiments)

Notes

Files written to the glacier directory:
climate_historical.nc

The historical monthly climate timeseries stored in a netCDF file.
