Evaluation and Calibration of Downward Longwave Radiation Models under Clear Sky Condition across the Sahelian Region of Nigeria

Downward longwave radiation (DLR) is a major component of the surface energy budget, yet the transferability of empirical clear-sky DLR models across Nigeria’s Sahelian climatic zone remains uncertain. This study evaluated eleven existing empirical DLR models and five locally calibrated modifications for Kano and Sokot...
