Short summary
Retrieving land surface temperature from thermal radiation is difficult because temperature and emissivity are strongly coupled. We developed a conditioning-controlled method that separates these quantities using paired ground-based longwave measurements. Tests with SURFRAD (Surface Radiation Budget Network) and BSRN (Baseline Surface Radiation Network) observations and known-truth simulations demonstrate stable retrievals and quantify their uncertainty without requiring satellite information.
