%X A generalized approach of three-dimensional variational data assimilation (G-3DVar) with 1-month assimilation window for land surface air temperature data was developed. As preliminary tests on this approach, two simplified forms of background error covariance matrix (B matrix for short) were applied to generate a high space-time resolution grid analysis field of land surface air temperature in January 2000 in China through incorporating the CRU monthly mean data into the NCEP daily reanalysis data based on...
