MOPITT & MOZART for MIRAGE and INTEX-B

Support Details

To assist with flight planning for MIRAGE-Mexico and INTEX-B, the following MOPITT and MOZART products will be available:

• Near-real-time MOPITT retrievals:
  Using an expedited data protocol, MOPITT data for the regions of interest will be transferred from NASA and the Level 2 CO retrievals made available within about 9 hours from the measurement time. Operational processing, which depends on the availability of the MODIS cloud mask product, will provide global CO distributions within about 4 days. Maps of the CO distributions for each day for the regions of interest will be produced along with several day data-composites. MOPITT uses a cross-track scan, and in the absence of persistent cloud cover, the instrument achieves close to global coverage in 3 days. Available under Near real-time CO
• Assimilation of MOPITT CO in MOZART:
  A continuous MOZART-4 simulation at T42 (2.8x2.8deg), with full chemistry, will include assimilation of the near-real-time MOPITT CO retrievals. Assimilated CO available under Near real-time CO Other MOZART species (O3, NOx, etc.) available under Assimilation Slices and Assimilation Maps
• Tracer forecasts:
  A second continuous high resolution (0.5x0.625 deg) tracer simulation will include a number of CO tracers of Mexico City and Asian industrial emissions, biomass burning in Asia and Central America, Siberian wildfires and US emissions. Each day, forecast runs of approximately 4 days will be run at high resolution to show the prediction of the CO tracers. Tracers are labeled with 'ffbf' for fossil fuel+biofuel emissions or 'bb' for biomass burning. Available under Forecast Slicesand Forecast Maps and Near real-time CO

Emissions

Since biomass burning events have the potential to produce a large perturbation to the climatological CO distribution carried forward in the assimilation, the CO emission inventory will be updated for the forecast runs based on MODIS fire counts. The University of Maryland produces MODIS Rapid Response product fire counts for the past 48 hours and 7 days. These fire count data, along with landcover and vegetation data from satellite will be used in the ACD fire emissions model developed by Christine Wiedinmyer.
