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

6


GMI File Naming Convention

For input files/g8/anon/pub/gmidata2/input/emissions/trop/

emisX_yyyy_Z_Res_Descriptor.ncemist_2004_m_2x2.5_auraharvardwship.nc

For output files/g8/anon/pub/gmidata2/output/gmic/aura2/2004/

problemname.datatype.filetypegmic_aura2_2004_jul.amonthly.nc

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

8


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

9


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

10


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,…’

11


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

12


Other Code Changes/Issues

New tropopause definitionNew lightning algorithmTagged CO/age of air capabilitySpecies names replace species indicesAdded flux diagnostic version to trunkComponentization of the codeAssisting GMAO with integration of GEOS-5 and the Combo Model chemistry

13


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

14


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

15


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

16


Automating/Streamlining GMI Runs

GMI Workflow toolGUI with “behind the scenes” scripts to do model runs “end to end”

Set up namelist fileSubmit jobGraphically display run progressView output data graphically
