Thin Cloud Rotating Shadowband Radiometer

8 January 2008 - 18 July 2008

Lead Scientist: Mary Jane Bartholomew

Observatory: sgp, sgp

The Thin-Cloud Rotating Shadowband Radiometer (TCRSR) is a prototype instrument intended to simultaneously retrieve cloud optical depth and effective drop radius in clouds with low liquid water paths (< 100g/m2). Following its design and testing in the summer and fall 2007, it was deployed at SGP during January through February of 2008. A number of observations were made to test the measurement strategy and instrument performance. The radiometer measures the angular distribution of scattered light in the forward scattering lobe of cloud drops in 6 narrow spectral bands each approximately10 nanometers wide and centered at 415, 500, 610 660 870 and 940nm. The purpose of deploying this instrument was to test a new instrument with the potential capability to make more accurate measurements of the optical thickness and effective drop radius for clouds of low liquid water paths than is currently available. Both of these properties are essential to understanding cloud-climate interaction.
