EarthCARE’s Broadband Radiometer: Uncertainties Associated with Cloudy Atmospheres EarthCARE’s Broadband Radiometer: Uncertainties Associated with Cloudy Atmospheres

The EarthCARE satellite’s Broadband Radiometer (BBR) consists of three telescopes and a rotating chopper drum (CD). Together they yield alternating measurements of totalwave (TW) (0.25 - >50 µm) and shortwave (SW) (0.25 - 4 µm) radiances with point-spread functions that translate to ∼0.6 km diameter pixels. The mission requires that SW and TW radiances be averaged over ∼100 km2 domains. Corresponding average longwave (LW) radiances are …
