CSU-NOAA-DRI  Single-particle Mass Spectroscopy of Ice Nucleating Particles (INSPECT)

update 24 Jan 2007

In this study, measurements were made of the concentrations and chemical composition of ice nucleating aerosols sampled from free tropospheric air and processed for conditions relevant to cirrus cloud ice formation. These studies were a collaborative effort between Colorado State University and the NOAA Aeronomy laboratory. Sampling was conducted at the Desert Research Institute's Storm Peak Laboratory, located on Mt. Werner (3200 m MSL) in Steamboat Springs, CO, during November 2001. Project investigators include Paul DeMott, Anthony Prenni and Sonia Kreidenweis from the CSU Department of Atmospheric Science, Daniel Cziczo, Daniel Murphy and David Thomson from the NOAA-CIRES and the NOAA Aeronomy Laboratory's Meteorological Chemistry Group. Collaborating and providing aerosol size distribution data were Randy Borys and Melanie Wetzel from the Desert Research Institute's Storm Peak Laboratory.
