SURFRAD All-Sky Downwelling Longwave Radiation (DLR) Dataset for Emissivity Estimation Study

Processed SURFRAD measurements used in the study “Estimation of Longwave All-sky Emissivity using Shortwave and Meteorological Measurements”. The HDF5 dataset includes downwelling longwave radiation (DLR), shortwave radiation measurements, meteorological variables, station metadata, and quality-control fields used for filtering, model development, and validation. The dataset is being deposited on 2026-06-01 and is under embargo until paper acceptance/publication. During embargo, metadata remain visible while files remain restricted.
