Generate soundings from MAPS or RUC Analyses and Forecasts, RAOBS, Profilers, Radiometers, or ACARS (restricted)

Please send comments about this page to Bill Moninger

Generally, analyses are available for the past 16 hours, and forecasts are available for various hours out to +36 hours. The time at which forecasts become available is somewhat unpredictable, because MAPS runs as soon as files are available, in order to produce results as soon as possible.

The plot page allows you to subsequently select additional data sources, times and locations.
