ADAS Technical Documentation
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.
, 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
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.
