Processing steps

Model Munger deals with three types of files:

• Raw data is model output stored for example as GRIB files. Model Munger can download the raw data for some models.
• Intermediate files are netCDF files containing vertical profiles in a single fixed or moving location. There may be multiple intermediate files, for example one for each model run. For some models, Model Munger extracts intermediate files from the raw data, but for other models, it uses the output from other tools.
• Output file is a harmonized netCDF file generated from one or more intermediate files. The output file contains up to 24 hours of data from a single fixed or moving location, possibly combined from different model runs.
