About
The GOES-R Sectorized Cloud and Moisture Imagery (SCMI) products monitor the Earth, atmosphere, and ocean system using the 16 spectral bands of the Advanced Baseline Imager (ABI) instrument aboard the GOES-East and GOES-West satellites. The measured reflectance/radiance within the visible/near-infrared and infrared bands are converted into brightness values (BVs) and brightness temperatures (BTs), respectively. These BVs and BTs are used to produce digital maps of clouds, moisture, and atmospheric windows, through which land and water are observed. There are several products using these single-band data. Channel differences and RGB composite imagery are among the popular derivatives. CMI data also provides input to scientific algorithms producing L2+ environmental products. SCMI products are available as rectangular tiles covering the geographic areas depicted here.
Limitations
Half-Disks Over the SBN: SCMI products denoted “Full Disk” (FD) on the Satellite Broadcast Network (SBN) cover only the Northern Hemisphere. (Among the NWS operations needing Southern Hemisphere SCMI, none depend on SBN for it.)
Full/Half-Disk Resolution Over the SBN: All SCMI products denoted “Full Disk” (FD) on the Satellite Broadcast Network (SBN) are resampled from their native (0.5km, 1km, or 2km) ground resolution to 6km resolution (to limit their file sizes).
Band 13 Full Disk imagery is sent over SBN at its full (2 km) ground resolution. (Like all “Full Disk” SCMI, it covers only the Northern Hemisphere: see previous note on “Half-Disks over the SBN.”)
