Error Analysis of Air Temperature Profile Retrievals with Microwave Sounder Data Based on Minimization of Covariance Matrix of Estimation Error
نویسنده
چکیده
Error analysis of air temperature profile retrievals with microwave sounder data based on minimization of covariance matrix of estimation error is conducted. Additive noise is taken into account in the observation data with microwave sounder onboard satellite. Method for air temperature profile retrievals based on minimization of difference of brightness temperature between model driven microwave sounder data and actual microwave sounder data is also proposed. The experimental results shows reasonable air temperature retrieval accuracy can be achieved by the proposed method. KeywordsError analysis; leastsquare method; microwave sounder;air temperature profile.

متن کاملAir temperature estimation based on environmental parameters using remote sensing data
This study is aimed at estimating monthly mean air temperature (Ta) using the MODIS Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI), latitude, altitude, slope gradient and land use data during 2001-2015. The results showed that despite some spatial similarities between annual spatial patterns of Ta and LST, their variations are significantly different, so that the...
متن کاملCombining Data from Ground-based Microwave Radiometers and Other Instruments in Temperature and Humidity Profile Retrievals
Ground-based microwave radiometry offers a new opportunity to automate upper air observations by providing information on temperature and humidity profiles as well as the integrated water vapour and liquid water amounts with high time resolution. To improve their relatively poor vertical resolution and provide a more complete picture of the vertical profile, radiometer observations can be combi...
متن کاملRetrieval and characterization of ozone vertical profiles from a thermal infrared nadir sounder
[1] This paper presents the first retrievals and validations of ozone vertical distributions from a set of high-resolution nadir thermal infrared measurements. These were obtained by the Interferometric Monitor for Greenhouse gases (IMG) instrument, which has operated on board the Japanese ADEOS platform between 1996 and 1997. The Optimal Estimation Method is used for the retrievals, along with...

The 89 and 150 GHz channels operated in window are sensitive to precipitation and humidity. The 183 GHz humidity-sensitive channels and 118 GHz temperature-sensitive channels of the Microwave Humidity and Temperature Sounder (MWHTS) on the Chinese Feng Yun 3C MWHTS (FY-3C MWHTS) polar-orbit meteorological satellite responds in part to precipitation. Combining 118 and 183 GHz channels, the paper...
