JPSS and GOES-R Multispectral Imagery Applications and Product Development at CIRA

VIIRS has  16 Moderate Resolution Channels (M-Band; 750 m resolution at nadir)  5 Imaging Resolution Channels (I-Band; 375 m at nadir) and  Day/Night Band (DNB, 750 m across the scan, nominal bandwidth from 500 to 900 nm), sensitive to the low levels of light that occur at night covering the visible, near-IR, midand longwave IR portions of the electromagnetic spectrum (0.412 – 12.0 μm). True Color capability (RGB composite of blue, green and red visible channels) first appeared on NASA’s ATS-3 satellite in 1967. Seen as a novelty with no operational value, subsequent geostationary satellites only had a single (red) visible channel. The AHI on Himawari-8 has brought back True Color to the geostationary platform and demonstrated it’s value. With the help of VIIRS, CIRA has developed improved True Color for AHI (HAC) and a synthetic version (SHAC) for ABI, which lacks a green-wavelength visible band.
