Table 10 Onboard calibration for CAI-2
From: Greenhouse gases Observing SATellite 2 (GOSAT-2): mission overview
Onboard calibration | Forward-looking (+ 20°) | Backward-looking (− 20°) | Purpose, frequency |
|---|---|---|---|
B1–B5 | B6–B10 | ||
Lunar calibration (AT scan) | X | X | Radiometric response degradation (per month, + 7° waning near full moon) |
Lunar calibration (CT scan) | X | X | Pixel-to-pixel response correction (per 2 months, -7° waxing near full moon) |
Nighttime calibration | X | X | Dark-time output (once per month, night ocean near new moon) |
