GMAO Observation Preprocessor

The goal of the observation preprocessor is to provide a framework for reading in various data types and outputting injested information to common formats.

Steps to build:

  1. Source g5_modules from GEOSgcm: source /discover/nobackup/asewnath/GEOSgcm/@env/g5_modules.sh. Feel free to use your own GEOSgcm build for this.
  2. git clone https://github.com/asewnath/observation_preprocessor.git
  3. cd observation_preprocessor/build
  4. You can leave ESMADIR in GNUmakefile as is or you can change the field to point to your build of GEOSgcm.
  5. make install
  6. cd ../

Now you have the executable run_preprocess to start preprocessing files.

Executable Usage

./run_preprocess <input file directory> <source> <output type> <output file directory> where

  • <input file directory>: directory that contains files to be preprocessed
  • <source>: input file type
  • <output>: output file type
  • <output file directory>: directory where output files will be saved

Possible sources: eumetsat, jma, wisconsin, noaa, kma, avhrr Possible output types: prepbufr, text

Example

To process feature-tracked winds from CIMISS into prepbufrs, run the following: ./run_preprocess /archive/u/asewnath/reanalysis/GOES/raw_data/data_stage_test/ wisconsin prepbufr ../output_prepbufr. This will take files from the archive and process them into prepbufrs which will be saved in the indicated output directory one level above the git repository.
