摘要: AbstractSensible heat flux is a turbulent driving interactions between the Earth’s surface and atmosphere, propelling local regional climate. While fluxes are measured in-situ, global scales require estimates at larger spatial which can be made using remotely-sensed satellite data. This study uses first-order approximation to calculate un-constrained hourly, terrestrial, 0.5°-resolution sensible land temperature consistent with High-Resolution Infrared Radiation Sounder (HIRS) retrievals, six reanalysis-based air products, dataset of Zilitinkevich empirical constant (Czil) values. constrained daily Bowen ratio available energy produce nine constrained, products. All resulting global, terrestrial averages within uncertainty range +/- 6.3 W/m2 from 38.8 annual average previously reported in literature. The product ne...
