Abstract :
Measurement of the continuum radiation with coherent microwave radiometers was implemented in several space-borne missions for Astronomy, Earth and Planetary Science. Planck Low Frequency Instrument (LFI) completed characterization of Cosmic Microwave Background (CMB) in 2013, Advanced Microwave Radiometer (AMR) has measured atmospheric humidity over oceans since 2008 on OSTM/Jason 2 mission, and MicroWave Radiometer (MWR) will measure water and ammonia distribution in Jupiter´s atmosphere when Juno spacecraft enters orbit in 2016. Future developments will include improvements in the spatial resolution of AMR with millimeter wave channels currently under development.
