Reproducibility archive for conditioning-controlled retrieval of broadband land surface temperature and emissivity from paired ground-based longwave irradiance measurements

This archive provides the frozen Version 12b scientific reproducibility materials associated with the manuscript “Conditioning-controlled retrieval of broadband land surface temperature and emissivity from paired ground-based longwave irradiance measurements” (egusphere-2026-858), by Collins Mito. It contains the authoritative scientific code, publication-generation code, and frozen machine-readable derived outputs used for the field and physics-based known-truth synthetic validation reported in the accepted manuscript. The archive preserves the established retrieval formulation, including the fixed eight-update Newton–Raphson implementation. Raw third-party SURFRAD and BSRN observations are not redistributed in this archive; they remain available from their respective public data services. This record supports traceability and reproducibility of the published analyses and derived results.
