OBS_INPUT

Submitted by Anonymous on Wed, 06/09/2021 - 20:19

Hello,

The documentation about the OBS_INOPUT section in the namelist file does not go into what the different observations are. Is there a part of the documentation that goes into those details? Specifically, I am trying to turn of dropsondes in the assimilation. I assume that they are included in the prepbufr files but it is not clear if I would turn off radiosondes in addition to turning of dropsondes by deleting those lines.

Thanks for the feedback!

Hi Stipo,

 

I think you will want to use the "convinfo" file to control data usage in this way---it contains multiple rows for each variable which are distinguished by more details than the namelist has. If you know the type codes of the drop sondes, you can find those in the "type" column and change the usage flag for those rows to turn them off. Check the third part of section 4.3 in the comGSIv3.7 user's guide for more details about data control in the convinfo options.

 

Let me know how it goes!
