The Meteorology Group (MG) seeks to improve the capability of range meteorological agencies to define the effects of astrogeophysical parameters on marine, missile, and space systems, and works to better the instrumentation and techniques used to measure and predict these effects. The MG mission includes the identification of present and projected range natural environmental support requirements, specification of error estimates of atmospheric data, and interchange of excess technical systems and equipment. Finally, the group works closely with other RCC groups to specify those atmospheric measurement systems, simulation techniques, and operational test procedures and standards that must be developed and acquired to maintain the ranges' capability for testing environment-sensitive systems.
