Dual Polarization Radiometer (DPR)
Mentor: M. Maahn
The Dual-Polarization Radiometer (DPR) measures brightness temperatures at the frequencies of 90 and 150 GHz. DPR is sensitive to particle orientation since it observes the brightness temperature difference between the vertical and horizontal polarization channels at 150 GHz, and it is especially important for the retrievals of particle shape and orientation with polarization observations. DPR also has a high sensitivity to the supercooled liquid water in clouds due to the high-frequency window channels.
