| − | Welcome to the January 2013 Newsletter of the NASA Air Quality Applied Sciences Team (AQAST). AQAST is a team of atmospheric scientists serving air quality management needs through creative use of Earth Science data and tools. We conduct a wide range of projects in partnership with air quality agencies at the local, state, regional, and national levels.

| + | |
| − | | + | |
| − | The new MODIS Level 3 aerosol product from AQAST member [mailto:Edward.Hyer@nrlmry.navy.mil Edward Hyer] has now been transitioned to [http://lance-modis.eosdis.nasa.gov/ NASA LANCE]. [https://earthdata.nasa.gov/about-eosdis/news/nrt-value-added-modis-aerosol-optical-depth-product-available Click here for press release]. Satellite detection of aerosols, or particles in the atmosphere, provides one of the most useful remote sensing products for air quality analysis. This new MODIS product supports a wide range of applications for air quality management. It provides global, gridded aerosol optical depth (AOD) at a resolution of 1/2-degree latitude-longitude in near-real time, for immediate access. In addition to reducing error in the AOD retrievals, the product includes quantitative uncertainty estimates at each data point.

These instructions describe how to add advected tracers to GEOS-Chem. Advected tracers are carried in the STT array (which is declared in GeosCore/tracer_mod.F), and are transported by the winds.
NOTE: Some advected tracers are also chemical species, which comprise GEOS-Chem's NOx-Ox-HC-aerosol chemistry mechanism.
1) Add tracers to input.geos under Tracer Menu
c) Increase “Number of tracers” accordingly
d) Add tracer number, name, molecular weight, and emitted species to end of tracer list
