· · · · Absolute Radiometric Calibration of Earth Radiation Measurement on FY-3B and Its Comparison with CERES/ Aqua Data 1 1 1 2 1 Qiu Hong , Hu Liqin , Zhang Yan , Lu Duanjun , Qi Jin (1 National Satellite Meteorological Center, China Meteorological Administration, Beijing 100081 2 Shanghai Institute of Technical Physics, Chinese Academy of Sciences, Shanghai, 200083) Abstract:The Earth Radiation Measurement (ERM) instrument onboard FengYun (FY)-3B satellite observes the Earth’s atmosphere with a narrow scanning fi eld of view (NFOV) and a wide nonscanning FOV (WFOV). For each fi eld of view, the measurements are made from two broadband channels: a total waveband channel covering 0.2–50 μm and a shortwave (SW) band covering 0.2–4.3 μm. The validation to the ERM calibration was carried out by comparing the unfi ltered longwave (LW) and SW radiances from ERM with those from Clouds and Earth’s Radiation Energy System (CERES) fl ight model (FM) 3 onboard Earth Observing System Aq
