Error in converting GRIB2 data using api2arl

Post by cherio » June 4th, 2019, 3:23 pm

I am trying to convert grib2 data into arl format and having trouble.
I appreciate it if you gave any advice in moving forward.


api2arl version:api2arl_v4

Meteorological data
  • Japan Meteorological Agency Meso-Scale Model (GPV-MSM)
  • Cycle:8/day (00,03,06,09,12,15,18,21UTC)
  • Timestep:3-hourly (for pressure surface)
  • Format:GRIB2

api2arl_v4 is an example to create a converter for GRID2 data. Some customization are always needed for different datasets. https://www.ready.noaa.gov/documents/Tu ... cnvrt.html

The cfg file lists the variables from the met data (atmgrb and sfcgrb) matching to those in HYSPLIT format (atmarl and sfcarl). The one you created currently is for ECMWF variables. You will need to come up with a similar table for the GPV-MSM variables and modify the code in order to read in the met data.
