Abstract:
The retrieval accuracy of Gband Vapor Radiometer (GVR) in Tianjin is examined through numerical simulation by using Beijing radiosonde data, which are divided into four seasons, in order to study the applicability of GVR with its own retrival algorithm in Tianjin. The results show that the accumulated liquid water retrival precision has no significant change with height. The relative deviation ranges of the accumulated liquid water in four seasons are 29% to 78%, 31% to 71%, 36% to 67%, 35% to 79% while the absolute deviation ranges are 004 to 0492 mm, 0075 to 0294 mm, 0074 to 0315 mm, 0116 to 0347 mm, respectively. The accumulated water vapor retrival precision decreases significantly in all the seasons, especially under the height of 3 km. The relative deviation range below 3 km of the accumulated water vapor in four seasons are 26% to 208%, 79% to 191%, 43% to 165%, 34% to 142%, while above 3 km are 64% to 897%, 125% to 369%, 132% to 50%, 118% to 301%. Compared with the other types of airborne microwave radiometers and ground GVRs used in the Arctic, the retrieval precision of the accumulated liquid water and water vapor in Tianjin is lower obviously.
