Desarrollo e implementación del control térmico del radiómetro terrestre RATI

The Argentinian Itenerant Tower Radiometer (RATI from its spanish acronym) its an L Band polarimetric radiometer developed by the IAFE Remote Sensing Group and CFRLS (Florida, US). It was designed to calibrate and validate radiometric satellite observations and remote sensing products. In this work, instrument main characteristics and the thermal control designed by IAFE Remote Sensing Group are presented. In this work, it is shown how the thermal control is a crucial component essential to robustly measure brigthness temperature.
