Imagery from earth surveillance satellites is examined to assess the potential usefulness of satellite data for monitoring air pollutant patterns and defining the associated meteorological conditions in southern New England. Three high ozone situations, one high total suspended particulate episode and one high sulfate episode are studied. Imagery from one or more of the following satellite systems: Landsat, NOAA/VHRR, GOES, and DMSP, ranging from the visible to the thermal infrared portions of the spectrum, are visually interpreted for each case. Because of the limited data sample, it is difficult to derive firm conclusions for particular imagery types or specified pollutants. Nevertheless, the results of the study indicate that there is a good correlation between certain types of high pollutant load (including ozone and sulfates) and haze and smoke, with accompanying reductions in visibility. There is good evidence that satellite imagery can display differences in reflectance (visible) or temperature (thermal infrared) due to some combination of haze, smoke and atmospheric pollutant load, on a regional basis. The greatest promise was shown by the DMSP thermal infrared imagery in application to high sulfate situations.
