Abstract:
The renewal of Lband upperair meteorological sounding system increases the atmospheric sounding precision, and the Lband “seconds level” data offer the basis platform of “seconds level” meteorological element data reanalysis for the Lband vetical high resolution profile. In order to discuss the application feasibility of Lband sounding vertical high resolution data, considering the acquisition conditions of other observation system “high time density” synchronous observation data, this paper selects the JICA (Japan International Cooperation Agency) PBL (planetary boundary layer) flux tower gradient observation to compare with, and also constructs the correlation model of Lband sounding data and flux tower surface layer meteorological information. The result shows that the Lband sounding vertical highresolution profile reanalysis surface data can preferably describe pressure, temperature, and humidity of the surface layer; the pressure, temperature, and humidity models have the feasibilities of calculating PBL surface layer pressure, temperature, and humidity. It provides the scientific proof and technical basis for the development and application of Lband detection “seconds level” data.On the basis of constructing Lband high resolution vertical profile reanalysis platform, it will help to develop national Lband sounding application in numerical model and promote the new technical development of radiosonde vertical high resolution information in numerical model assimilation system.
