Questions on Validating Atmospheric Profiles


Tony, John,

In the latest TT5 report, NPROVS (NOAA Products Validation System) as well as SASBE (Site Atmospheric State Best Estimate) are mentioned as elements of TT5 activities. I have three questions  Read the rest of this entry »

Reference guidelines are online for discussion


The paper “A guide for upper-air reference measurements” by F. Immler, J. Dykema, T. Gardiner, D. N. Whiteman, P. W. Thorne, and H. Vömel went online on the interactive Journal “Atmospheric Measurement Techniques” where it is open for public discussion for eight weeks (link).

Discussion on the co-location / coincidence issue


The following paragraphs from an e-mail by John Dykema describes how co-location and coincidence could be formalized.  As an example, the measurements of a temperature profile by a sensor on a balloon and a profile retrieved from microwave radiometry are assumed.

Once we have two well-characterized sensors with rigorously assessed and validated uncertainties, then we can make robust recommendations on co-location.
