Book Description
Aerosol distributions measured with a Royco 220 particle counter over Northern Europe in Spring 1976, Fall 1976, and Summer 1977 are presented. The vertical aerosol structures were measured with an integrating nephelometer and are presented to give context to discrete aerosol size distribution and concentration measurements at altitudes near 500 m, 3000 m, and 6000 m. Analysis of aerosol data indicates that the aerosol distribution shapes at altitudes of 1.8 km and 6.0 km are very similar to distributions measured earlier over the midwestern U.S. using an impactor. Sampling analysis, and comparison to nephelometer measurements, indicate the aerosol measurements probably always represent the dry aerosol particle distribution vice the actual distribution (in balance with existing relative humidity) sensed by the nephelometer. These data provide an excellent picture of the relative changes that were found to occur in the vertical, and in space and time, with changing synoptic conditions.

Book Description
The ability to measure atmospheric aerosols over ocean surfaces has been demonstrated using several different satellite sensors. Landat data originally showed that a linear relationship exists between the upwelling visible radiance and the aerosol optical thickness. Analysis of NOAA-6 AVHRR data obtained at several different locations, in coincidence with ground truth measurements, show that the Channel 1 (0.65 micron) radiances can be used to determine the aerosol optical thickness. The good agreement between the results at different locations suggests that the technique could be used in an operational system. A technique using channel 1 and Channel 2 (0.86 micron) radiances to determine the aerosol size distribution is discussed, and, in spite of uncertainties in the satellite and ground truth data, a preliminary analysis shows that useful estimates of the size distribution can be obtained.
