Bottom: INTERPOLATEDSONDE relative humidity output profiles for 1 July 2015 through 5 July 2015 at the Southern Great Plains.
A new version of the Interpolated Sounding (INTERPOLATEDSONDE) value-added product (VAP) is released for use with historical data and current production.
The INTERPOLATEDSONDE VAP transforms sounding data into continuous daily files on a fixed time-height grid at one-minute time resolution from the surface up to a limit of approximately 40 kilometers. The grid extends to 332 levels in order to be sure to capture the full height of soundings. Most soundings terminate somewhere between 25 and 30 kilometers, above which no data are provided. Between soundings, the VAP linearly interpolates—estimates values between two values—atmospheric state variables in time for each height level. In addition, INTERPOLATEDSONDE data provide relative humidity scaled to microwave radiometer observations.
This vap will be the basis, or input, for a new Merged Sounding VAP expected to be released to evaluation in the summer of 2016.
Feedback and use of the data are welcomed and encouraged. For questions or to report data problems, please contact Tami Toto or Mike Jensen. To access the data set, please browse the ARM Data Archive. (Go here to create an account to download the data.)
