GOES-16 (GOES-East) “Red” Visible (0.64 µm), Low-level Water Vapor (7.3 µm), Mid-level Water Vapor (6.9 µm) and Upper-level Water Vapor (6.2 µm) images (above) showed the southward propagation of an undular bore across Kansas, Oklahoma and Texas on 10 July 2019. This feature appeared to play a role in convective initiation over the Texas Panhandle —... Read More

Approximately once every 239 days, a HBT (Hydrazine Bipropellant Thruster) Flush is performed on GOES-R series satellites — this flushing burn limits the build-up of ferric nitrate in the HBT valves. Following a GOES-17 (GOES-West) HBT Flush that was conducted on 10 July 2019, a navigation offset of about 145... Read More

GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed narrow ribbons of fog over the northwestern portion of Lake Superior on 08 July 2019. A person attempting to navigate from Grand Portage, Minnesota — located northeast of Grand Marais Airport, identifier KCKC — to Isle Royale became lost in the fog and eventually... Read More

Possibly compounding the fog-related visibility problem, GOES-16 Natural Color Red-Green-Blue (RGB) images (below) revealed that dense smoke from Canadian wildfires was lingering and also recirculating slowly northward across Lake Superior; this smoke occasionally reduced the surface visibility to 4 miles at Houghton, Michigan (identifier KCMX).

GOES-16 (GOES-East) True Color Red-Green-Blue (RGB) images from the AOS site (above) showed the signature of dense smoke from Canadian wildfires that was being transported southward across parts of the Upper Midwest on 06 July 2019. While much of the smoke remained aloft, some of it was reaching the surface... Read More

On the following day, the smoke settled farther southward over Wisconsin and Michigan (below). Much of the smoke again remained aloft, but continued to persist within the boundary layer at Baudette and International Falls — and it did briefly restrict the surface visibility at Green Bay in northeastern Wisconsin.
