Observed Sounding Archive

This page shows current and recent observed radiosonde data in skew-t format. An archive of seven days of data will always be available. The images are created using a sounding analysis program called NSHARP. Sounding data will flow to this site as early as HH:30 after the hour, and will also re-run old hours to fill in late data.

NOTE: This data is experimental and may not always be available in a timely fashion.
