Abstract

A number of sea-borne radiation thermometers have been developed and are being used to validate sea surface temperature (SST) measurements made by satellite-borne instruments. Provided principles specified by Quality Assurance for Earth Observation (QA4EO) are followed, measurements carried out with these sea-borne radiation thermometers can be treated as Climate Data Records (CDRs). The purpose of this document is to summarise the minimum number of calibration steps that are required in order to ensure that SST measurements carried out with sea-borne radiation thermometers can be considered traceable to an SI standard. The treatment of uncertainties in SST measurements is summarised, and typical uncertainty budgets which satisfy each calibration step are presented in order to provide guidance to the preparation of uncertainty budgets and to ensure that SST measurements have an appropriate Quality Indicator (QI) associated with them. The uncertainty budgets presented in this document should only be considered as guidance, as the exact form of the uncertainty budgets will depend on the details of each calibration step.
