Thread: I need assistance with re-gridding in python
Post: RE: I need assistance with re-gridding in python
| I discovered that the above was incorrect, and that the "interpolate_to_model" function can only handle one variable at a time. Thus, I separated both variables (onedaymax and fivedaymax) as in the fo... |
