All,

Sorry, but neither the DSSAT WEATHERMAN, nor the individual crop models have a way to "input" hourly weather data.  You certainly cannot import hourly values into WeatherMan.

The CERES models do not use hourly values at all.  The CROPGRO model internally computes hourly values, but that is based on input of daily Tmax, daily Tmin, and daily solar radiation integral.

If you are highly expert in coding, you are welcome to contribute this "hourly input in WeatherMan", to the DSSAT group, so that we could use it too.  CROPGRO could use hourly input, but would require significant coding to "input" that, rather than to use the internal conversion from daily Class A weather inputs.

For now, you should only input daily values.

Subject: How to use hourly weather data?

Dear all,

I want to use hourly measured weather data in DSSAT.

How can I import hourly values into WeatherMan?

Thanks a lot in advance,

best regards,

Sebastian
