The output of effective ice nuclei from silver iodide generators can vary by at least three to four orders of magnitude as a function of the type of generator device employed and its operational efficiency. A detailed consideration of each phase of the process of calibrating silver iodide generators shows that with care meaningful calibrations to within a factor of 1.5 are possible.

The repeatability of actual calibration experiments together with space closed volume experiments support the validity of generator testing procedures.

During the past several years, many weather modification programs have been incorporating meteorological satellite data into both the operations and the analysis phase of these projects. This has occurred because of the advancement of the satellite as a mesoscale measurement platform, both temporally and spatially, and as the availability of high quality data has increased. This paper surveys the applications of meteorological satellite data to both summer and winter weather modification programs. A description of the types of observations needed by the programs is given, and an assessment of how accurately satellites can determine these necessary parameters is made.
