Abstract:A New global weighted temperature model(GWMT_N) was built using reanalysis data during 2007-2011 offered by NCEP to solve the remarkable limitation in ocean area of Global Weighted Mean Temperature (GWMT)model.Periodically semiannual effect of Tm was taken into account in the new model.The accuracy of GWMT_N model was verified with 650 radiosonde stations in 2011 and COSMIC occultation in 2011.The results show that GWMT_N successfully avoid the limitation of GWMT,and its accuracy on land was even improved.The overall accuracy of GWMT_N is equivalent to that of Bevis formula.For the new method does not require observed temperatures on land,it can be applied more widely in GPS meteorology.
