GMI Directory Structure
Added new directory and directory structure on dirac
/g8/anon/pub/gmidata2/input/output/
…/output/gmic/aura2/2004/diagnosticsdocs/progs/users/
/g8/anon/pub/gmidata still exists, untouchedInput data also available on discover
/discover/nobackup/projects/gmi/gmidata2Met fields are on-line

New GMI Inputs
EmissionsAdded capability to use daily emissionsEmissions inputs now can include ship emissions
ChemistryPhotolysis
Monthly rates can be used (GOCART aerosols)Aerosol interaction with photolysis (fastjx53c) added
JPL06-2 mechanism is currently usedDefault mechanisms
124 species for Combo Model85 species for Troposphere Model

New GMI Outputs
Variables added to all output filesGrid box heightGrid box area (mcor)Grid info (ai, bi, am, bm)
New outputs to some filesFile description that is placed in headerPotential vorticityTropopause pressureRelative humidityCloud optical depthOverhead column O3
Surface emissions for aerosolsGrid box mass

New GMI Outputs
New output filesSet with freq settings
Column ozone (.columnoz.nc)Hourly data (.hourly.nc; can select species/levels to output)Instantaneous daily mixing ratios (.idaily.nc)
Four overpass times (formerly “noon_species”; .overpass1.nc, etc.)
Output file name changes.const.nc is now .amonthly.ncStation .column.nc is now .profile.nc

Namelist File Changes
Namelist sections reorganized and restructuredInput/output species changed from indices to names
From:flux_species(1:124) = 1, 1, 1, 0, 0, 1, 0…
To:fluxSpeciesNames = 'CH2O, CO, H2O2, HNO3,…’

Namelist File Changes
Profile stations selection simplifiedFrom:
col_diag_site(1:201) = 'SPO', 'MCM', 'HBA',…col_diag_lat_lon(:,1) = -89.98, 335.20,col_diag_lat_lon(:,2) = -77.83, 166.60,col_diag_lat_lon(:,3) = -75.56, 333.50,
To:stationsInputFileName
Master list with station names, locations, and descriptionsFile name set in namelist file
colDiagStationsNames = 'SPO, MCM, HBA,…’User-selected list of stations to study

Other Code Changes/Issues
Disclaimer/Notice of Release addedOpen-source process has begunVersion numbering system established
Three digit system: X.Y.ZCurrent version: 2.0.0
Made GMI simulation date Y2K compliantNew gmi-users mailing listModel runs transitioned to discover

Unintended GMI “Features” Addressed
Soil NOxTruncated vertical ozone profileMixing ratio blow-up due to convectionDivide by zero potential in convectionAdvection code array boundsH2 level not set properlyStratospheric chemistry divide by zero potentialHO2 heterogeneous chemistry reaction

Automating/Streamlining GMI Runs
Met field processing/regridding scriptsScripts automatically begin processing when GMAO releases new files
Model run submission/monitoring scriptsSubmits a series of model runsEmails user when each phase is complete
Namelist/met file list generation scripts
