IFR (Instrument Flight Rules) Probability estimates the likelihood that IFR conditions are occurring by fusing GOES-17 satellite data with model output. The satellite-derived products give output of low IFR, (LIFR), IFR, and Marginal Visual Flight Rules (MVFR). In aviation, the difference between these classifications is generally:Low Instrument Flight Rules (LIFR): Ceilings are less than 500 feet above ground... Read More

Color-enhanced wind speeds observed from Synthetic Aperture Radar (SAR) data on the second RADARSAT Constellation Mission satellite (RCM-2), shown above in AWIPS (Click here for a similar image online at this website) show parallel lines of enhanced wind speeds, a wind structure suggestive of a bore (click here for many previous...

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) and “Red” Visible (0.64 µm) images (above) showed Tropical Storm Alex after it reached tropical storm intensity at 0900 UTC on 05 June 2022. Overshooting tops within the deep convection exhibited infrared brightness temperatures of -80ºC or colder (shades of violet).GOES-16 Infrared Window (11.2 µm) images... Read More

Some National Data Buoy Center buoys do include webcams that provide sky information (link). How well do those observations compare to IFR Probability fields, as shown above in an image from RealEarth? There are three BuoyCams along the Oregon coastline, as shown in the image below, and 3 more offshore... Read More
