Questions about chanprof/frequencies

[liu xuan]

Hi，

I’m using RTTOV_SCATT for microwave radiation simulation in a cloudy situation. In my program， I set the number of profiles to 1, but I would change the value of the profile parameters in a loop. but I found that the value of some pointer properties chanprof and frequencies would change and cause my program to give an error. Can I just set the values of chanprof and frequencies, or is there a better way to do it?

Thanks

Hi,

If you are simulating the same set of channels for each profile, then you can set chanprof and frequencies once (by calling rttov_scatt_setupindex) before the loop over your profiles. You don’t need to modify them for each call to RTTOV-SCATT.

If you are getting errors related to the chanprof and/or frequencies arguments, can you provide more information, such as the error messages, and more details on how you are setting up your simulations.

Best wishes,
James

Hi James,

I found the source of the error of chanprof/frequencies because the order of calling rttov_alloc_direct and rttov_scatt_setupindex is reversed.Thank you very much for your help.

Best wishes,
