Transcript of Poster Nov19 V1
Surface reflectance as obtained from SeaWiFS satellite (http://daac.gsfc.nasa.gov/data/dataset/SEAWIFS/01_Data_Products/02_LAC/01_L1A_HRPT/index.html)
Rayleigh Corrected
Minimum surface reflection which contains no aerosol – a “true” surface reflection
AOT obtained through an algorithm which takes the difference between the original surface reflectance and the minimum surface reflection
Algorithm for obtaining Aerosol Optical Thickness (AOT)
Case Study: Kansas Agricultural Smoke
Zoomed in portion of Kansas, red dots represent fire pixels and yellow arrows represent the wind vectors. Heaviest smoke is seen in the AOT image in blue

Surface reflectance
Yellow dots represent surface PM2.5 measurements taken at 12:00pm, AIRNOW
