LGPt application issue #107

Open WeirdCxychen opened 5 months ago

WeirdCxychen commented 5 months ago

Hi,

I am curious about the growing period of the study area. In NB1, some of the results are the LGPt0, LGPt5, LGPt10 for the whole study area, but in NB2, because of the parameters we provide in 2 charts, we could decide the crop type, and then the "start date irrigation/rain-fed" given in NB2 is for a specific crop type. Is that appropriate to use the growing period in NB1 and start date in NB2 to get the start date and end date for specific crop type (like maize) ?

Best Reagrds,

XinyueChang.

Hi @WeirdCxychen,

From your question, I would say that the way of interpretation to the AEZ outputs are not correct.

LGPtx calculation in PyAEZ Module I tells about how many days in the area that can support plant growth in terms of actual temperature. This agro-climatic indicator doesn't tell the starting date (plantation date). Note: 'x' in here is temperature threshold (0, 5, 10 Deg Celsius).

The crop calendar(starting date) output from Module II in PyAEZ is interpreted as the day of year that if you start to plant at that DOY, you will get the corresponding maximum attainable yield, which is from Module II yield output (both rainfed and irrigated).

Regards,

Swun Wunna Htet

After thinking carefully about your interpretation, I realized that I made a mistake about the conceptions. Thank you so much for your reply!
