ISPA-2010 QC Radiosonde Dataset. Version 1.0

The Inhibition of Snowfall by Pollution Aerosols (ISPA) was the third phase of a field campaign performed to better quantify the amount of water in snow pack lost due to pollution aerosols. The first and second phases of ISPA took place in 2002 and 2007. The third phase was conducted during January and February 2010. ISPA was organized by the Desert Research Institute (DRI) and each phase took place near Steamboat Springs, Colorado. The primary site was located on Mount Werner at the Storm Peaks Laboratory (SPL), and a GPS Advanced Upper Air Sounding System (GAUS), operated by the National Center for Atmospheric Research, was located near the base of the Steamboat ski resort. A total of 32 radiosonde launches were made from the GAUS site. In addition to the radiosonde sounding system, there were a suite of surface meteorology instruments, a microwave radiometer, microwave rain radar and a laser distrometer.
