As covered in the “Problems with Parallax” series, at high latitudes geostationary satellites can experience displacement of features and lower resolution due to parallax. In this addendum, we are comparing the NGFS fire product produced by ABI and VIIRS, which are found on the geostationary GOES-18 and the polar-orbiting NOAA-21 respectively. This first set of

If you look at something close to your face, you might notice its location seems to change depending on whether you have one or both eyes open. Perhaps the object seems to move left or right relative to the background, without even moving your head. This is what is known as parallax, the apparent difference

In Alaska conditions can change quickly. Fog, snow, ice and clouds all impact transportation, on the ground and in the sky. Pilots rely on weather forecasts and reports to determine if it’s safe to even take off and to stay safe once in the air. Ground-based weather observations show conditions at a specific point and

Alaskan’s are used to winter weather impacting their daily commutes, from cold weather and snow storms, to icy roads and ice fog. However, one hazard that is often overlooked in blowing snow. Blowing snow is snow that has already fallen and is lofted into the air by strong winds. Severe blowing snow events can reduce

On April 6, 2024, GINA’s newest antenna – dubbed “UAF-5” – was lifted into place atop the University of Alaska Fairbanks’ Usibelli Engineering Building. On September 6, 2024, the installation of UAF-5 was completed with the addition of it’s protective radome. This 3-meter antenna will replace the “Big Dog” antenna atop UAF’s Akasofu Building, which

Starting June 21 and updated every Monday, fire points videos will be posted to keep track of Alaska’s fire season. Consistent with last year’s summary, each video shows a timelapse of the fire heat points detected by GINA over the course of the 2024 Alaska Fire Season. Recent fire points are displayed as bright red
