ICECAPS Observatory at Summit Station, Greenland

In the spring of 2010, the ongoing measurements at Summit Station (72° 36'N, 38° 25'W, 3250m), atop the Greenland Ice Sheet, were significantly enhanced with new capabilities to observe cloud and atmosphere properties. These upgrades were made by the Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) project, which is collaboratively-lead by the Universities of Colorado, Idaho, Wisconsin, and Oklahoma. New instruments at the site include: cloud radar, depolarization lidar, micropulse lidar, infrared spectrometer, two microwave radiometers, ceilometer, precipitation occurrence sensor, and a twice-daily radiosonde program. The ICECAPS program will continue through summer of 2014 at a minimum. Overall programmatic and logistical support for these operations is provided by the National Science Foundation. Additional instrumental support is provided by the NOAA Earth System Research Laboratory, the DOE Atmospheric Radiation Measurement Program, and Environment Canada.
