gvrpwv: G-Band Vapor Radiometer Precipitable Water Vapor

Precipitable water vapor retrieved from GVR data in March 2012. Dotted lines show the retrieval uncertainty (1 standard deviation).

The G-Band Vapor Radiometer Precipitable Water Vapor (GVRPWV) value-added product (VAP) computes precipitable water vapor using neural network techniques from data measured by the GVR. The GVR reports time-series measurements of brightness temperatures for four channels located at 183.3 ± 1, 3, 7, and 14 GHz.
