Microwave Radiometer (MWR)

NSSDCA ID: 2011-040A-04

Mission Name: Juno
Principal Investigator:Dr. Michael A. Janssen

Description

The Microwave Radiometer (MWR) was designed to use six passive microwave antennas, sensitive to wavelengths between 1.3 centimeters and 50 centimeters, to perform deep atmospheric sounding and composition measurements to a depth as great as 1,000 atmospheres (about 550 kilometers below the visible cloud tops). Objectives include: (1) determining the global O/H ration (water abundance) in Jupiter's atmosphere; (2) measuring latitudinal variations of composition, temperature, cloud opacity, and dynamics in Jupiter's deep atmosphere; and (3) measuring the microwave brightness temperatures of Jupiter over all latitudes at wavelengths that fully sample the atmospheric thermal emission at all altitude levels from the ammonia cloud-forming region to below the water cloud-forming region.
