Complementary roles of microwave and infrared instruments in atmospheric sounding
Abstract
Radiance measurements in the infrared and microwave regions respond differently to changes in the atmosphere. These differences in response lead to differences in the ability to derive profiles of atmospheric parameters such as temperature and moisture. A summary of the characteristics of each region is presented, followed by an evaluation of the results of simulation studies and extrapolations from existing instruments, both of which were designed to assess the relative advantages of the two wavelength regions. The studies show that the combination of the information from the two spectral regions leads to more accurate retrievals than can be obtained from either spectral region alone at all levels of the atmosphere.
