Cost, weight, and size less than half of conventional radiometers. Ground-based instrument measures temperatures in upper atmosphere while correcting for liquid water in clouds. Addition of channel at 51 GHz to channels used for making upper-atmosphere temperature profiles adds little to cost of microwave radiometer. Eliminates need for separate water-vapor radiometer subsystem, with its attendant size, weight, and cost. Instrument light, compact, and portable and inexpensive enough for use in sensor arrays. Availability encourages use of microwave radiometry for routine weather forecasting.
