31. The satellite carried Imaging multi-spectral radiometers on board for radio sensing of the resources. 32. The radiometer , Global Positioning System receiver and laser retroreflector array were built in the United States. 33. Analysis showed inadequate thermal shielding of the sensor's radiometers due to excessive heating at perihelion. 34. Using Moderate Resolution Imaging Spectrometer ( MODIS ) to calibrate Advanced Very High Resolution Radiometer reflectance channels. 35. Following his departure, Even Bekkedal, formerly with In Dialogue With Radiometer , joined the band. 36. Calculations analyzed from these radiometers are where scientists first noticed the depletion of ozone caused by rockets. 37. On May 25 and May 28, the stream of data from the scanning radiometer began to stutter. 38. For weather and climate monitoring, microwave radiometers are operated from space as well as from the ground. 39. Soon after satellites were first used for observing the atmosphere, MW radiometers became part of their instrumentation. 40. Conversely, radiometers are typically used for remote sensing from the visible, infrared though radio frequency range.
