Update to observations used for verification purposes (GDAS for upper-air and NDAS for surface) #736

Closed jwolff-ncar closed 1 year ago

Description

Historically, EMC has used GDAS prepbufr files for global model verification and NDAS prepbufr files for regional model verification. This introduces some problems when looking to compare scores for a global model and a regional model. EMC has decided to unify the observation sources for global and regional verification by using GDAS prepbufr files for all upper air fields (including CAPE) and using NAM (or RAP or URMA) prepbufr files for all surface fields. The rationale is using GDAS provides for use of files that have the latest data cutoff for upper air observations, but also takes advantage of one of the regional modeling systems for surface verification to use all the mesonet data that are assimilated into the regional systems.

Solution

Add a pull script for GDAS prepbufr files Add logic to MET tasks to process GDAS files and use them for verification of upper-air fields. Modify the MET logic to only use NDAS files for surface verificaiton
