I'm trying to do some 72-hour runs using GFS input data from 2016, and I'm getting errors like this:
420:FATAL from PE 420: diag_util_mod::get_date_dif: in variable t2 is less than in variable t1
The run starts fine, but on the sixth hour (always with na=96 in the logs) it encounters this error. Rajesh seems to remember that the GFS format changed around this time, and indeed I can run using 2017 06 01 initialization date, but not 2017 05 01. Is there a utility to convert the GFS data to the new format, or does anyone have code I can incorporate into MR Weather App to allow it to read the older GFS format? I am happy to run two different instances of the model for the two types of GFS input.
Thank you in advance for any help or tips on this,
