The animation of GOES-17 visible imagery (Band 2, 0.64 µm), above, (created at the CSPP Geosphere site) shows the characteristic signal of Sun Glint — the moving bright region. Sun glint (also discussed on this blog here, here, here, here and — for moonglint: here!) occurs when radiation from the Sun reflects... Read More

As an anomalously-strong upper-tropospheric jet streak was moving across the Mid-Atlantic region on 20 November 2022, GOES-16 (GOES-East) Upper-level Water Vapor (6.2 µm) images (above) displayed numerous 6.2 µm Derived Motion Wind (DMW) vectors having speeds of 190 knots and higher — with the jet streak axis passing just to the north of the Wallops,...

RADARSAT-2 observations of SAR data near/around the island of Guam in the Marianas Islands continue in November (as previously discussed here, here and here). Overpasses on 15 November (above) and 17 November (below) contain features that deserve comment. For example, there is an obvious seam (and a less-obvious second seam)... Read More

Day Night Band imagery from NOAA’s AOML Direct Broadcast site, above, shows a low-level circulation with deep convection over the center at 0719 UTC. GOES-16 Low-Level water vapor (Band 10, 7.3 µm) mesoscale sector one imagery, below, (from this website) shows abundant mid-level dry air to the south of the Nicole. Nicole is near... Read More
