The G-band Vapor Radiometer (GVR) is an airborne passive radiometer developed by ProSensing, Inc. It measures brightness temperature at 183.31 GHz to determine precipitable water vapor and liquid water path. GVR is highly sensitive to water vapor, making it ideal for measurements in low-humidity conditions. It has an antenna beamwidth of 1.5 degrees and a data rate of up to 20 Hz. GVR can be configured for ground-based operations and has been used at the Department of Energy (DoE) Atmospheric Radiation Measurement (ARM) Central Facility site in Barrow, Alaska.
