ISPA-2007 QC Radiosonde Data


The Inhibition of Snowfall by Pollution Aerosols (ISPA) was the second phase of a field campaign with the primary objective to better quantify the amount of water in snow pack lost due to pollution aerosols. The first phase of ISPA took place in 2002. The second phase was conducted during January and February 2007. Both phases took place near Steamboat Springs, Colorado. ISPA was organized by the Desert Research Institute (DRI), and the primary site was located on Mount Werner at the Storm Peaks Laboratory (SPL), with an EOL Integrated Sounding System located in town, near the base of the Steamboat Ski Resort. The ISS was equipped with a UHF boundary layer wind profiler, Radio Acoustic Sounding System (RASS), radiosonde sounding system, a surface meteorology tower, and a ceilometer for measuring cloud base heights. A total of 71 radiosonde launches were made from the ISS site, 70 of which are included in the final archive.
