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 Author: L.
