GOES-16 Mesoscale Sector 1 imagery, in its default position over the metropolitan New York City aviation hub, also views western New York. It was therefore able to view the beginning of a large fire at a cardboard container recycling and manufacturing facility in Niagara Falls (Youtube link) on 20 November 2020. GOES-16 Band 7 shortwave... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.35 µm) and Fire Temperature Red-Green-Blue (RGB) images (above) showed a period of extreme behavior of the East Troublesome Fire in Colorado around and just after sunset on 21 October 2020. This rapidly-growing wildfire produced a series of pyrocumulonimbus (pyroCb) clouds — the coldest pyroCb cloud-top 10.35 µm infrared brightness temperatures... Read More
The East Troublesome Fire in Colorado expanded greatly on 21 October (click here for more information), and produced pyrocumulus clouds. NOAA-20 overflew the fire at around 1930 UTC (linked-to overpass map from this site) on 21 October, and NUCAPS profiles, shown above, diagnosed the stability of the mid- and upper-troposphere. The toggle below between the NOAA-20 VIIRS Visible (0.64 µm) and Infrared (11.45 µm) imagery and NUCAPS Sounding availability... Read More
Low-level water vapor imagery, above, from early morning on 17 October 2020, shows the characteristics of strong low-level winds in the lee of the Colorado Rockies, namely a warm trench and herringbone-like structures that suggest turbulent flow. This region is near the Cameron Peak fire, a long-lived conflagration to the west of... Read More
