[RegCNET] sunshine duration

[gaoxj at cma.gov.cn]

Dear all,

Sunshine duration (hours of sunshine) is a variable in the conventional meteorological observation. This is also needed by some impact models. My questions is:

1) Can we derive this variable based on other variables in the current RegCM output? 2) Can the model calculate it during the integration and output, or postproc it?

Thanks.

Best regards,

Gao
