NCAR is deploying two Integrated Sounding Systems ISS in the Reno basin for the Desert Research Institute. ISS3 is located in Truckee Meadows near a construction site off of Trademark Drive. ISS2 is on Washoe Lake. Only ISS3 has a sounding system. The table below links to plots of some of the data being recorded at each site.

There are summary pages for several of the categories of realtime plots. Each summary is a table of thumbnail images of all of the plots on the website for that category. The directories of plot images contain plot images listed by filename without any thumbnail images, so they will load more quickly. The ISS plot directories are subdivided into days, with links to conveniently browse to the preceding or succeeding day.
Currently ISS2 is transferring data to ATD every hour (or at least attempting it), while ISS3 transfers about every two hours. Plots are generated for ISS data as they arrive: profiler winds, RASS temperatures, surface measurements, and GLASS soundings. The profiler radar generates wind and temperature consensus profiles every half-hour, usually. Surface measurements are recorded every minute, and skew-t plots of GLASS naturally only appear when soundings have been launched.
The plots are anchored at 5z and 17z and updated every time new data arrive from the sites. Plots may not appear for periods when no data have been received.
Signal-to-noise ratio (SNR) and moments, along with other parameters, are being recorded about every minute from the radar PC serial port. Plots of these data are called SOAP (Serial Output ...) images. They are not yet available on the web site.
Of all the plots in the summary pages, the most recent ones for each ISS site are assembled onto a single status page. Note that the times on the plots will not necessarily be for the same periods, depending upon the last time data were received for a particular plot category. These pages give quick status information as they show the latest time for which data have been received from a site and a quick look at those data in a thumbnail image. Each category title on the summary page links to the full page of thumbnails for that category.
The site log files (from the TKLOG program developed at ATD) are received from the site and converted to HTML. Thus the logs will only be current as of the time of the most recent successful data transfer from the particular site.
Once the data arrive here, they are placed on the ATD web site from where they can be downloaded. Here is the URL for the top of the data repository:
