Welcome to the Shipborne Radiometer Network!

Join us for the second ISFRN Workshop on 17 - 18 September 2020. Details are now online!

The International Sea Surface Temperature (SST) Fiducial Reference Measurement (FRM) Radiometer Network (ISFRN) sets out to develop and promote an international network of ocean and remote sensing scientists who share a particular interest in promoting and improving the use of shipborne infrared radiometers for measuring skin SST at the surface of the ocean, comparable to measurements made by satellite infrared radiometers. This includes operators, designers and builders of such instruments as well as the  user of the data.

The scope of the ISFRN activity can cover all aspects of the science and technology of shipborne radiometers used to measure SST. This includes

  • exchange of operating advice and information that promote best practice for radiometer deployments,

  • establishing protocols for shipborne radiometry including the validation of observations traceable to NMI reference standards,

  • agreeing formats for skin SST data retrieved from ship radiometers,

  • setting procedures for quality control in order to meet agreed standards of accuracy, and

  • provide a single access point of the data collected around the world.
