Mozart Download

MOZART-4 results for a subset of the globe and a range of dates can be downloaded from this page. Output is provided every 6 hours. Each request is provided as a single netcdf file. We recommend that you download a single day for your region to check the file size and then request a range of dates that will result in a manageable file size. Questions about MOZART-4 and requests for additional dates can be addressed to Louisa Emmons (emmons at ucar . edu).

Two simulations are now available here: (1) MOZART-4/NCEP and (2) MOZART-4/GEOS5.

Simulation (1) MOZART-4/NCEP is the standard simulation described in Emmons et al., GMD, 2010. It is driven by NCEP/NCAR-reanalysis meteorology and uses emissions based on POET, REAS and GFED2 (see Emmons et al., 2010). These results are at 2.8x2.8 deg horizontal resolution and have 28 levels. Files for 1 day for the whole globe are 250 MB.
Special note about O3 in MOZART-4/NCEP: This simulation includes the synthetic stratospheric ozone tracer SYNOZ. Because of this the species labeled 'O3' is unrealistic in the stratosphere and upper troposphere. We recommend that the species 'O3RAD' be used instead for regional model boundary conditions. Please see Emmons et al., GMD, 2010 for more information about SYNOZ in MOZART-4.

Simulation (2) MOZART-4/GEOS-5 is driven by meteorological fields from the NASA GMAO GEOS-5 model. SYNOZ and O3RAD are not used in this simulation, as there seems to be reasonable strat-trop exchange when using GEOS5 fields in MOZART-4. This simulation uses anthropogenic emissions based on David Streets' inventory for ARCTAS (http://www.cgrer.uiowa.edu/arctas/emission.html) and fire emissions from FINN-v1 (Wiedinmyer et al., Geosci. Model Devel., 2011). These results are at 1.9x2.5 deg with 56 levels. Files for 1 day for the whole globe are 940 MB.

The 'date' and 'datesec' variables contain the date and time of the MOZART output. To verify the date of the downloaded files, please use 'ncdump -v date'. The program ncview does not properly interpret the 'time' variable and calculates an erroneous date.

MOZART-4/NCEP results are available for Jan 2, 2003 to Dec 1, 2009.
MOZART-4/GEOS5 results are available for Jan 1, 2007 to Aug 10, 2011.
Real-time MOZART-4 results that can be used for boundary conditions are available from the MOZART-4 forecast page.
