Infrared cloud imager measurements at Barrow, Alaska

Poster PDF

Description

The infrared cloud imager (ICI) measures spatial and temporal cloud statistics, along with cloud optical depth up to a value of approximately 3. Because this instrument measures wide-angle, longwave infrared images, the result is a continuous day-night datastream that overcomes the difficulties of visible-wavelength imagers for nighttime and high-latitude winter clouds. The ICI is deployed as part of a field campaign at the North Slope of Alaska site in Barrow, Alaska, extending from July 2012 into August 2013. This poster will describe the instrument and show examples of data obtained in Barrow during this year-long deployment.
