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 strongly 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).

Simulation 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 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. There is a change of variables between August 29 and 30, 2014; consequently, data requests across that boundary will deliver slightly fewer variables.

MOZART-4/GEOS5 results are available for January 1, 2007 to January 21, 2018, however we highly recommend using our CAM-chem output instead, available 2001-2019.
