Sensor

CBERS-4 Infrared Multispectral Scanner 2 is a four-channel passive optical scanner on CBERS-4, with PAN/VIS-NIR, two SWIR bands and one thermal-infrared band.^[1]^[2] Its bands span 500-900 nm, 1550-1750 nm, 2080-2350 nm and 10.4-12.5 um; the visible/SWIR bands are 40 m and the thermal band is 80 m over a 120 km swath.^[3]^[4] The infrared payload is known both as IRMSS-2 / Infrared Multispectral Scanner - 2 and as IRS / Infrared Medium Resolution Scanner / IRSCAM.^[3]^[4] It has demonstrated land-surface-temperature and emissivity retrieval use on CBERS-4 data.^[4]

IRMSS-2 is the CBERS-4 infrared multispectral scanner.
Multispectral optical imaging
[wmo-irmss2][catalyst-cbers4] Bands at 500 to 900 nm, 1550 to 1750 nm and 2080 to 2350 nm at 40 m on CBERS-4; edge covers its reflective bands only.
Thermal infrared imagingvia CBERS-4
[wmo-irmss2] One thermal band at 10.4-12.5 um, 80 m; edge covers that band.
