I.M. Systems Group, Inc. (IMSG) is seeking candidates to support the Environmental Modeling Center (EMC) of the National Centers for Environmental Prediction (NCEP) to evaluate the quality of aviation fields analyzed by the Real Time Mesoscale Analysis (RTMA) system. The RTMA is an hourly-updated 2-dimensional variational analysis system that provides gridded analyses of a wide variety of surface weather elements (e.g. 10 m wind speed and direction, 10 m wind speed gust, visibility, ceiling, total cloud cover, 2 m temperature, etc.).
