Readme for PSS (GTS-resolution) data (found on data/hires_sodne/level0/gts_data/pss) Prior to DYNAMO, 45 operational sounding sites in the large scale domain of the experiment were identified as Priority Sounding Sites (PSS). It was felt that data from these sites were important to providing an enhanced analysis over the large-scale DYNAMO domain. An effort was made to obtain the high vertical resolution sounding data for these sites, by sending requests to the weather service offices of most of the countries involved. While these requests were met with limited success, in the end hi-res data were provided by 21 of these sites. For the remaining 24 sites, the GTS-resolution data were collected during the field phase of the experiment. Because many sites experienced delays in sending their data over the GTS in real time, a post-experiment effort was made to retrieve a complete set of data for each of these PSS sites. This was done by accessing the data through the University of Wyoming sounding data server (http://weather.uwyo.edu/upperair/sounding.html) which from past experience is believed to be quite complete. At each site, the GTS-resolution data were processed with gross limit and vertical consistency checks. Objective QC flags were assigned and then these flags were adjusted by visual inspection of each sonde using the "xsnd" visual editor.
