The document describes the spectral channels and spatial resolutions of an instrument. It has 6 channels in the visible to near infrared spectrum ranging from 0.47 to 2.26 μm. The spatial resolutions vary between channels from 0.5 km to 2 km. It also provides tables comparing the instrument's measurements to CERES data over different months and conditions.

7. Channel Wavelength [μm] Spatial Resolution
1 (Blue) 0.47 (0.43–0.48) 1.0 km → 2.0 km
2 (Green) 0.51 (0.50–0.52) 1.0 km → 2.0 km
3 (Red) 0.64 (0.63–0.66) 0.5 km → 2.0 km
4 (NIR) 0.86 (0.85–0.87) 1.0 km → 2.0 km
5 (NIR) 1.61 (1.60–1.62) 2.0 km
6 (NIR) 2.26 (2.25–2.27) 2.0 km
