Resolution
High spectral resolution of ~0.3 nm around the Oxygen absorption bands. Other spectral areas with less pronounced absorption features will be measured at medium spectral resolution between 0.5 and 3 nm.
[Best Resolution: 300m]
Swath
150 km swath
[Max Swath: 150 km]
Waveband
Several bands of the range 500-780 nm, with two types of spectral resolution: Low (1-2 nm) and High (0.1-0.5 nm)
| VIS (~0.40 µm - ~0.75 µm) |
| NIR (~0.75 µm - ~1.3 µm) |
