Code to process/regrid the GMAO GEOS-IT data for input into GEOS-Chem

This package was originally developed by Bob Yantosca for GEOS-FP data processing. It is adapted for GEOS-IT by Lizzie Lundgren. README text is taken from GEOS-FP data processing tutorial written by Bob Yantosca in 2014.

GEOS_IT

Development of the code and scripts used to process the "raw" GEOS-IT met data for input into GEOS-Chem

Root-level subdirectories

Code/ : Contains Fortran code adjust/ : Contains NCL code (not used much anymore) bin/ : Contains executable and input files that specify data directories and options for data reprocessing doc/ : Manual pages will be built here when you type 'make doc' jobs/ : Contains job scripts created by the doGeosItMulti driver script lib/ : Fortran library files (.a) will be built here during compilation logs/ : Log files fromt he GOEs-IT data processing jobs are sent here mod/ : Fortran module files (.mod) will be built here during compilation perl/ : Contains scripts (written in Perl) to download and processing GEOS-IT data

The most important directories here to be aware of are Code, bin, logs, and perl.

Scripts in perl/ subdirectory

There are several scripts in the perl/ subdirectory that control the entire data download and regridding process.

Scripts for downloading data: getGeosIt : Downloads 1 day of GEOS-IT met data from NASA checkGeosIT : Checks to see if the GEOS-IT data files were downloaded

Scripts for file management: cleanJobs : Removes job scripts in the jobs/ subdirectory cleanLogs : Removes log files in the logs/ subdirectory moveGeosIt : Moves files from temp dir to data dir (called by doGeosIt) delGeosIt : Removes GeosIt "raw" met data files (for manual use) purgeGeosIt : Removes old GEOS-IT "raw" data (called by doGeosIt)

Scripts for regridding data: Dates.pm : Perl modules containing common subroutines doGeosItMulti : Main driver script; extracts/regrids 1 day of GEOS-IT data doGeosIt.input : Input file with settings for doGeosItMulti runMet : Called by doGeosIt

Scripts for automating the data download and regridding process: schedGeosIt : Calls purgeGeosIt, getGeosIt, and doGeosIt schedGeosItInAdvance : Schedules regridding jobs in days advance
