CEOS Analysis Ready Data Surface Temperature Product Family Specification V6.0

The Committee on Earth Observation Satellites (CEOS) produces and maintains a series of Analysis Ready Data (CEOS-ARD) Product Family Specifications (PFS) across Earth observation technologies. Each PFS provides a mandated list of specifications for pre-processing, metadata, and documentation, providing value for interoperability, benchmarking, procurement, and user confidence.

This submission presents an overview and update on the CEOS-ARD Surface Temperature (ST) PFS Version 6.0, which recognises and accommodates the evolving user base, technology, and applications of space-based infrared data from public and commercial sector missions. The ST PFS applies to designers and deployers of missions operating in the thermal infrared (TIR and MWIR) and microwave wavelengths at all scales.

New metadata requirements are being introduced to support the varying types of surface temperature products: land surface temperature, surface brightness temperature, and water surface temperature. The PFS also features updates in line with the Future CEOS-ARD Strategy, with modifications to requirements on data quality, radiometric stability, and other general metadata while also providing better support for higher level applications and harmonisation between CEOS-ARD PFS. The CEOS-ARD Oversight Group invites feedback, contribution, and early adoption.
