Sentinel-3 MWR
The design and specifications of the SENTINEL-3 MWR have been based on those of the Envisat MWR. The instrument will measure brightness temperature at 23.8 GHz and 36.5 GHz covering a bandwidth of 200 MHz in each channel. The lower frequency channel is mostly sensitive to atmospheric water vapour and the higher frequency channel to cloud liquid water. Conceptually, it is a balanced Dicke radiometer for brightness temperatures below the Dicke load temperature. Balancing is achieved by means of a noise injection circuit. For brightness temperatures higher than the Dicke load temperature, a conventional Dicke mode is used.
