ICECAPS

Overview

The Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) Project is a comprehensive ground-based instrument suite that expands the Arctic Observing Network by adding cloud, atmosphere, and precipitation measurements, and associated higher-order data products, to Summit, Greenland at the top of the Greenland Ice Sheet (GIS).  The ICECAPS Project instrumentation include a cloud radar, two microwave radiometers, an Atmospheric Emitted Radiance Interferometer, an X-band precipitation sensor, a ceilometer, a micropulse lidar, and a twice-daily radiosonde program, which take focused measurements of the cloud, atmosphere, precipitation, and radiation properties over the GIS.  The data products produced from the ICECAPS Project include:

  • Atmospheric State - temperature and moisture profiles through the troposphere and lower stratosphere
  • Cloud Macrophysics - cloud occurrence, vertical boundaries, and temperatures
  • Cloud Microphysics - cloud phase, water content, optical depth, and particle size
  • Precipitation - precipitation type and rate
  • Cloud Radiative Forcing - impact of clouds on the surface radiation balance
