Hi , Dr Bi:

 

    I'm very grateful for your answer. Now I have another doubt : what is the meaning of 'Tas' ? Is it temperature of atmosphere or surface ? Please tell me , OK ? Thank you vey much.

  

   Moreover, I have another problem. I have some doubts about the variables 'flw' /'fsw' /'flwd' /'sina' in 'SRF.*.ctl'. I comprehend these four variables in this way. ' flw ' is 'net longwave radiative flux', 'fsw' is 'net shortwave radiative flux', 'flwd' is 'downward longwave radiative flux', 'sina' is 'downward shortwave radiative flux'. Is it right ?

 

  I look forward to your information silently.

 

 

                         yours sincerely : ljy_926
