The Solar Ultraviolet Imager (SUVI) on GOES satellites revealed an equatorial coronal hole directed towards Earth on the 11th and 12th of December.  Coronal holes appear as dark areas in the extreme ultraviolet, or the 195 Angstroms band on SUVI. They appear dark because they are cooler and less dense regions... Read More

The 2023 NOAA Satellites Virtual Science Fair (VSF) concluded this month with top projects identified. The VSF involves middle and high school students (G6-12) working with GOES (geostationary) or JPSS (polar-orbiting) satellite data in projects of their own design conveyed via a scientific poster. High school submissions also require a short video where students... Read More

If you see something, like a blog post for example (link, this shows an airmass high in Total Precipitable Water crossing the North Pole) and you’re curious what JPSS satellite imagery might look like with that something, how can you proceed? If the data are in the recent past, one... Read More

According to NOAA’s Great Lakes Surface Environmental Analysis (GLSEA) the Great Lakes were 11.6% ice covered on February 2nd when an arctic air mass was descending southward over the region. The cold air boosted ice coverage to 14.7% on February 3rd, less than half of the average extent (1973-2022)... Read More
