ISPA-2002

This is an NSF funded project with the Desert Research Institute's Storm Peak Laboratory (SPL) at Steamboat Springs, Colorado. The project is examining the effect of pollution aerosols on snowfall rate. The principal investigators at SPL are Randy Borys and Doug Lowenthal, and at NCAR the main investigators are Steve Cohn and Bill Brown. NCAR is deploying an Integrated Sounding System ISS with MAPR, an advanced wind profiler which will be used in this project to make high resolution measurements of snowfall distribution and wind. We are also deploying an array of surface meteorology instruments, radiosonde weather balloons, a radiosonde mounted on a gondola at the Steamboat ski area, and a second 1299 MHz profiler pointing vertically only.
