[GRASS-user] î.evapo.potrad negative ETpot values

[Yann Chemin]

Hi Niels,

Can you provide me with a test data so that I can debug the reason behind
this behaviour?

You can indeed get the functions from the source code at
http://trac.osgeo.org/grass/browser/grass-addons/grass7/imagery/i.evapo.potrad

Thank you,
Yann
