ADAS Technical Documentation

ADAS, the ARPS Data Analysis System, is a 3-dimensional analysis program. This implementation is using Rapid Update Cycle (RUC) forecasts from the National Center for Environmental Prediction (NCEP) as background fields. Oklahoma Mesonet , surface airways, NOAA wind profiler , and radiosonde data are used in the analysis. The analysis method is a successive correction scheme known as the Bratseth method [Tellus, 1986]. This method is designed to asympotically approach the result of a statistical (optimal) interpolation. The analysis grid has resolution of 12 km in the horizontal and is stretched in the vertical from about 50 m near the ground to nearly 1 km near the top. The analysis is run hourly on an IBM RS/6000 Power workstation on a timed queue and the WWW products are generally available by 30 minutes after each hour. However, due to the varying load on the machine, that performance cannot be guaranteed.
