NOAA / NESDIS Air Quality Satellite Products Liqun Ma, Zhaohui Cheng, Hanjun Ding , Mark Ruminski , NOAA/NESDIS/OSPO, College Park, MD Shobha Kondragunta, Jian Zeng, Pubu Ciren, Chuanyu Xu, Xaioyang Zhang, Hai Zhang, NOAA/NESDIS/STAR, College Park, MD Abstract The NOAA National Environmental Satellite and Data Information Service (NESDIS) is operating, developing, and hosting numerous satellite-derived products for use by the air quality community. This poster presentation provides a cursory review of the products and outlines their relative merits as tools for air quality applications. NESDIS Operational Air Quality Products GASP The GOES Aerosol Smoke Product provides total Aerosol Optical Depth (AOD). These 4 kmx 4 km half hour data are available with 1 hour latency and 20% accuracy. Both the eastern and western domains are operational. Hazard Mapping System (HMS) This blended GOES/POES product is produced using human analysis and fire points from N 15/18/19/Metop. A/B HRPT AVHRR (FIMMA), GOES-E/W VIS (ABBA), Terra & Aqua MODIS. It is issued for the prior day in JPG, GIS, and KML. Integrating S-NPP VIIRS fire point into HMS system is under development. http: //www. ssd. noaa. gov/PS/FIRE/hms. html FIMMA AVHRR Fire Detects from the Fire Identification, Mapping and Monitoring Algorithm is an automated algorithm to detect fires from Advanced Very High Resolution Radiometer (AVHRR) data from NOAA 15, NOAA-18, NOAA-19 and Metop-A/B http: //www. ssd. noaa. gov/PS/FIRE/Layers/FIMMA/fimma. html http: //www. ssd. noaa. gov/PS/FIRE/GASP/gasp. html ASDTA Smoke The Automated Smoke Detection and Tracking Algorithm provides Smoke AOD from 2 days prior and is used for validation of NWS smoke forecasts. Both the eastern and western domains are operational http: //www. ssd. noaa. gov/PS/FIRE/ASDTA/asdta. html GBBEPx The GBBEPx system produces global biomass burning emissions. The product contains daily global biomass burning emissions (PM 2. 5, BC, CO 2, OC, and SO 2) blended fire observations from MODIS and geostationary satellites. It also produces hourly emissions from geostationary satellites. http: //satepsanone. nesdis. noaa. gov/pub/FIRE/GBBEPx WF_ABBA Wildfire Automated Biomass Burning Algorithm uses geostationary satellite(Goes –E/W, MTSAT and Metosat) data to detect and characterize biomass burning. http: //www. ssd. noaa. gov/PS/FIRE/Layers/ABBA/abba. html MODIS Dust Mask Algorithm MODIS dust mask algorithm is responsible for dust detection for all MODIS pixels for the granules over the United States during daytime. The algorithm output is written in GRIB and Net. CDF format for dust flags with values: 0 (no dust) and 1 (dust). The algorithm also produces two bytes of quality control output which includes: Day/Night flag; Land/Ocean flag; Sunglint flag; and Cloud flags. http: //www. ssd. noaa. gov/PS/FIRE/DUST/dust. html S-NPP VIIRS AOT S-NPP VIIRS Aerosol Optical Thickness(AOT) is a unitless quantity that is a measure of atmospheric aerosol loading. Aerosols are solid/semi-solid suspended matter such as smoke, dust, sea salt, volcanic ash, sulfate, nitrate and a combination of organic/inorganic particles. NESDIS is also running an AOT BUFR converter to generate AOT BUFR file for users. Hosted Products Aura OMI Aerosol Index Produced every 3 hours at 13 x 24 km^2 resolution and ~30% accuracy. http: //satepsanone. nesdis. noaa. gov/pub/OMISO 2/index. html
