Abstract

Presenting results of five comparisons between ACPs and IRISs and the difference between the longwave irradiance measured by the ACPs and IRISs versus the average irradiance measured by the WISG. The process of CIMO recommendation to establish the world reference for measuring the atmospheric longwave irradiance with traceability to the International System of Units (SI) is also presented.
