The purpose of this splinter meeting is to establishing a dialog across the communities which measure surface solar and longwave radiation over land and sea.  Objectives of the effort to be established, as a foreseen joint action of Atmospheric Observation Panel for Climate (AOPC) and Ocean Observation Panel for Climate (OOPC) of the GCOS, would include i) to share knowledge and experience on operational procedures for in-situ observations, ii) document the calibration methods and traceability, and iii) assess the uncertainties to be associated with the different approaches.
It is believed that, establishing a coordinated dialog endorsed by GCOS, will reduce the gaps between the two community and mutually increase their performances. The initiative will also support a harmonized evaluation of the global earth surface energy balance, providing better benchmarks for remote sensing product and model validation.
