Description

Ground-based two-channel microwave radiometers (MWRs) data have been used for over 20 years to retrieve perceptible water vapor (PWV) and liquid water path (LWP)- two important parameters for convective parameterization in large-scale models and cloud-resolving model simulations. During the Midlatitude Continental Convective Clouds Experiment (MC3E), in addition to the ARM 2-channel MWR deployed at the Southern Great Plains (SGP) central facility, BNL operated a five-channel (22.2, 23.0, 23.8, 26.2, 30.0GHz) MWR at the S05-Purcell, OK site [34.985 Lat., -97.522 Lon.]. Here we present PWV and LWP retrievals using the new MWRRET multi-wavelength retrieval algorithm for the BNL MWR. Time series of PWV/LWP are presented in the context of large-scale meteorology observed during the MC3E campaign and compared to radiosonde and Central Facility MWR observations.
