Abstract : Variations in marine stratocumulus microphysics during FIRE IFO 1992 are observed and analyzed through the use of NOAA 10/11/12 AVHRR satellite data. Maritime and continental aerosols in clear-air and cloudy regions are characterized by particle size index, optical depth, and low cloud analysis at visible and 3.7 micrometers wavelengths. Use of satellite-detected radiances to resolve aerosol type and distribution prove useful in determining implications of cloud reflectance changes due to modification by aerosol particles. Air masses were clearly defined and showed distinctive signatures in aerosol characteristics and cloud reflectances at 3.7 micrometers wavelengths. Air mass characteristic sources consisted of industrial aerosols out of Europe and desert dust from the Sahara Desert.
