Answers to Exercises from Session 1
These are the answers to the exercises from the previous page. Feel free to ask a MET representative if you have any questions!
Instructions: Modify the METplus configuration files to add relative humidity (RH) at pressure levels 500 and 250 (P500 and P250) to the output.
Answer: In the GridStat_add_rh.conf param file, add the following variables to the [config] section.
BOTH_VAR5_LEVELS = P500, P250
Instructions: Review the list of file paths and configure a Example wrapper use case to loop over all of the files.

Answer:The configuration file you created should look something like this:
PROCESS_LIST = Example
LOOP_BY = INIT
INIT_TIME_FMT = %Y%m%d%H
INIT_BEG = 2022011200
INIT_END = 2022011212
INIT_INCREMENT = 6H
LEAD_SEQ = 0,1,2,3
EXAMPLE_INPUT_DIR = /scratch1/NCEPDEV/rstprod/com/gfs/prod
EXAMPLE_INPUT_TEMPLATE = gfs.{init?fmt=%Y%m%d}/{init?fmt=%H}/atmos/gfs.t{init?fmt=%H}z.pgrb2.0p25.f{lead?fmt=%3H}
