Summary

This is an NSF funded project being carried 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 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 and radiosonde weather balloons.
