Infrared Interferometer Spectrometer and Radiometer (IRIS) instrument were consistent with sulfur volcanism. Nimbus 5 carried an Electrically Scanning Microwave Radiometer and Temperature-Humidity Infrared Radiometer. Electrically Scanning Microwave Radiometer (ESMR). She worked on the 240-GHz radiometer for the Earth Orbiting System Microwave Limb Sounder. MWR (Microwave Radiometer) was designed for measuring water vapour in the atmosphere. It carries Very High Resolution Radiometer and DRT payloads to provide meteorological services. A Nichols radiometer does demonstrate photon pressure. Advanced Microwave Scanning Radiometer (AMSR) and Cryosat-2 provide separate records. The radiometer provided data on the temperatures of Jupiter's atmosphere and satellites. The Crookes radiometer turns when the MFP is larger than the size of the vanes. This apparatus is sometimes confused with the Crookes radiometer of 1873. A Microwave Radiometer ("Juno") detected many more in 2018. This was confirmed when Mariner 2 made radiometer measurements of the temperature in 1962. The science mission continues with data being returned only by the radiometer instrument. Furthermore, there are different measuring methods, such as the two-sphere radiometer and the constant-air-temperature sensor.
