| Aerosol Optical Thickness | Product is composite global field of Aerosol Optical Thickness based on one month of data of aerosol optical thickness retrievals over the oceans. It is derived from AVHRR channel 1 and has a resolution of 100 km. The optical thickness at each gridpoint is the average of the optical thicknesses calculated for each week within the month at that gridpoint. Product Links: |

| GOES Aerosol Smoke Products (GASP) | Product provides aerosol optical depth (AOD) using GOES visible channel imagery and utilizes a cloud screening algorithm. A look-up table is used to estimate the AOD using the difference in reflectance between current cloud free pixels and those of a 28 day clear sky composite image. Over the GASP-East domain, the automated smoke detection and tracking algorithm (ASDTA) uses a source apportionment technique to derive AOD associated with fires.

| GOES Biomass Burning Emissions Product (GBBEP) | The GOES-E/W Biomass Burning Emission Product (GBBEP) algorithm calculates emissions (PM2.5, CO, CH4, CO2, TNMHC, NH3, N2O, NOX, and SO2) released from biomass burning fire detections and uses the GOES WF_ABBA (Wildfire Automated Biomass Burning Algorithm) fire product as input. The WF_ABBA detects instantaneous fires in sub-pixels using 3.9 µm and 10.7 µm infrared bands by assuming that the thermal radiance in a 4 km pixel is a linear mixture of radiance from a fire target and background. The GBBEP uses GOES-11/12 WF_ABBA sub-pixel fire sizes to generate diurnal patterns taken as the proxy of burned areas for every hour of the previous day. Product Links: GBBEP-East and GBBEP-West |
