Storm Peak Laboratory

Research

STORMVEx

The U.S. Department of Energy  deployed the second ARM Mobile Facility (AMF2) to Steamboat Springs, Colorado, in 2010-2011 for the Storm Peak Lab Cloud Property Validation Experiment (StormVEx). The already extensive instrument suite at SPL was augmented with additional state of the art instruments that are typically used for airborne cloud research.  SPL collected in situ cloud and precipitation property measurements while the AMF2 operated at a location approximately 2.4 km west and 500 m in elevation.  SPL researchers were funded by the U.S. Department of Energy Atmospheric Science Research Program in 2015 to continue working with the data collected during StormVEx. 

ISPA

Inhibition of Snowfall by Pollution Aerosols (ISPA) is an ongoing project supported by the National Science Foundation since 2001. This study investigates the relationships among pollution aerosols, snow growth by riming, and snowfall amounts on the ground. ISPA results have important implications for water resources in the inter-mountain West. The principal investigator is Doug Lowenthal of DRI.

Hygroscopic Growth of Organic Aerosols

Aerosols contribute to the Earth’s radiation balance directly by absorbing and scattering light and indirectly by nucleating cloud droplets which increase planetary albedo. Both effects depend on hygroscopic growth, but the contribution of organics to aerosol hygroscopicity is not well understood— limiting efforts to model those effects. The study addresses several important questions through field measurements, laboratory experiments, and modeling. This project is a collaboration with Drs. Hallar, Lowenthal, Zielinska, and Chow at DRI; Dr. Mazzoleni at Michigan Technolgical University; Dr. Collins at Texas A&M, and Dr. Clegg at University of California, Davis. Aerosol filter samples were collected at Storm Peak Laboratory for future analysis.
