Update GFS v17 p8 suite to address cold bias (ufs-community#1055)
Browse files Browse the repository at this point in the history
A SRW App user noticed an issue with the FV3_GFS_v17_p8 physics suite, that the surface temperatures were dropping unrealistically throughout the forecast. This PR addresses that issue by updating the FV3_GFS_v17_p8 physics suite in the parm/FV3.input.yml file.

This issue was discovered in the SRW App v2.2.0, but since the FV3_GFS_v17_p8 physics suite is not officially supported for the release, the change will only go into in the develop branch.
