GOES-16 (GOES-East) True Color RGB images from the CSPP GeoSphere site (above) showed patches of remnant thick first-year ice in southern Hudson Bay, Canada (off the coast of Ontario) on 07 August 2022. The diurnal tide cycle within Hudson Bay was evident in the ice motion during the period 1230-2020 UTC.Farther to the... Read More
Suomi-NPP VIIRS Visible (0.64 µm) images (above) showed a variety of Beaufort Sea ice floe motion within the nearshore waters of Alaska and Yukon during the 20-21 June 2022 period. Just north of Utqiavik (or Barrow, PABR), a sharp “shear line” was seen on 20 June — with a narrow... Read More
GOES-16 Cryosphere products — Ice Mask, Ice Concentration and Ice Surface Temperature — have been developed and are in a testing phase. The AWIPS screenshot above shows ice concentrations over parts of Lakes Superior, Huron and Erie. These products are created over the Full Disk ABI domain in regions of... Read More
