Abstract
The atmospheric weighted mean temperature (Tm) determines the calculation accuracy of perceptible water value. Recently, a variety of global Tm empirical formulas and models have been developed using different databases, which have defects of limited spatial resolution. To address this issue, we establish a high-resolution global Tm model, GTm_X, using global reanalysis data in 2011–2013 provided by the ECMWF. GTm_X achieves a global spatial resolution of 1° × 1°. Its accuracy is verified using 2011–2013 Tm data from 703 global radiosonde stations. GTm_X exhibits higher accuracy than Bevis’s formula and other empirical models currently in use, including GTm_III, and GTm_N.
