Microwave radiometer gas leak
WebInitial results from the Seasat scanning multichannel microwave radiometer indicate that the sea surface temperature can be measured with a root-mean-square sensitivity of 1.2°C or better. The first microwave map of sea surface temperature for the entire Pacific has been produced. Web7 mrt. 2024 · The Microwave Radiometer Profiler (MWRP) provides time-series measurements of brightness temperatures from 12 channels between 22.235 and 58.80 GHz. These channels are sensitive to the presence of liquid water and precipitable water vapor and to the atmospheric temperature and humidity profile. Authors: Cadeddu, Maria …
