The 13th Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment will take place in Pasadena, California at the California Institute of Technology. MicroRad is a unique gathering where the microwave radiometry community has an opportunity to present new designs, research results, technological advances and unique innovations in the field of passive microwave remote sensing. The meeting will cover wide radiometry applications and fields such as soil moisture, ocean salinity, cryosphere, ocean dynamics, sounding, radiometer calibration, radio frequency interference issues, new technologies etc. The meeting is expected to attract 200 scientists and engineers sharing their results. MicroRad is sponsored by the Geoscience and Remote Sensing Society of the Institute of Electrical and Electronics Engineers.
