REMARKS
ProSensing Inc. has developed a G-band (183 GHz, 1.5 mm wavelength) water Vapor Radiometer (GVR) for measuring low concentrations of atmospheric water vapor and liquid water. Using four double sideband receiver channels, the instrument measures brightness temperature at 183.31 +-1, +-3, +-7 and +-14 GHz, to then retrieve precipitable water vapor and liquid water path using a neural network algorithm. A ground based version of this instrument has been continuously operating at the North Slope of Alaska DOE ARM site since April, 2005. An airborne version of the instrument, packaged and wired to operate from a standard PMS 2-D probe canister, has been successfully tested during the CloudSat validation experiment onboard the NRC Canada Convair-580 aircraft through the winter of 2006-07.
