Rainfed and irrigated yield the same

[maobw12]

I have a question, I simulated the same value of NB2 yield under rainfed and irrigated, why is this happening? I thought it was due to the rainfall data, but after I changed the rainfall data, the result is still the same. May I know where I should address this issue?

Hi @maobw12,

I think there's something misstep happened during preprocessing all raster data into numpy arrays (very rectangular in the northern part). From my experience, it has something to do with reprojection to geographic coordinate system and regridding method. Please readjust the data accordingly as gridded data preparation is very sensitive to geographic locations shift if the settings are not correctly done.

I'll check. I would like to ask if the rainfall data is in mm/day, so is it monthly average rainfall?Or is it cumulative rainfall data?

@maobw12,

If you're using daily data, precipitation should be total precipitation per day.

If you're using monthly data, precipitation should be suitable with monthly mean precipitation.
