Sulfur Dioxide
Product Description
sulfur_dioxide
AIRS Standard Sulfur Dioxide Product
AIRS sensitivity to sulfur dioxide is low and is primarily visible in volcanic activity. However the AIRS instrument is very sensitive to atmospheric aerosols, such as dust and ash. AIRS sulfur dioxide and aerosols are not produced in geophysical units (e.g. concentration or optical thickness), but due to absorption the sulfur dioxide is expressed in terms of a temperature difference. The detection of the presence of volcanic sulfur dioxide is made by comparison of radiances, and the flags originate in the AIRS L1B Product. They are propagated to the Level 2 Standard and Support Products.
Data Source
