WXtoIMG: A Legacy in Weather Satellite Decoding

August 5, 2025August 11, 2025 Carl

A Brief History WXtoIMG was a pioneering and widely beloved software for decoding Automatic Picture Transmission (APT) signals from NOAA (National Oceanic and Atmospheric Administration) polar-orbiting weather satellites, as well as WEFAX transmissions from geostationary satellites. Developed by Craig Anderson from Auckland, New Zealand in 2000, and distributed via the Abstract Technologies website, WXtoIMG emerged … Delve Deeper “WXtoIMG: A Legacy in Weather Satellite Decoding” »

Spectral Imagery and False Colorization of Geostationary Satellite Data Updated June 9th 2024 Geostationary satellites like GOES, Himawari, Meteosat, FENGYUN, and Elektro primarily acquire imagery in various infrared (IR) bands along the electromagnetic spectrum. While some possess limited visible band capabilities (typically blue and red), these are often desaturated and not used for generating true-color … Delve Deeper “False Color Imagery” »

Imagery Processing, Life, Satellites, Science

The four seasons, namely spring, summer, fall, and winter, are part of the natural cycle of the Earth’s orbit around the sun. Each season is defined by a unique combination of astronomical and climatic factors, which affect weather patterns, animal behavior, plant growth, and human activities. The GOES-R Series satellites, operated by the National Oceanic … Delve Deeper “The Seasons” »

Hunga Tonga Hunga Haʻapai Eruption On 20 December 2023 Hunga Tonga Hunga Haʻapai erupted after being relatively inactive since 2014, causing a large plume that was visible from Nukuʻalofa. The Volcanic Ash Advisory Centre Wellington NZ issued an advisory to airlines. Explosions could be heard up to 170 kilometers (110 mi) away. The initial eruption continued until 2 am on … Delve Deeper “Hunga Tonga Eruption” »

Software and Coding for Post Processing of Imagery

Imagery Processing, Satellites, Science

Receiving satellite imagery all by itself is interesting science and, for many of us a great hobby. Setting up your satellite receiving station, whether for GOES-R series satellites, or Himawari, FY2 or FY4, GEO-KOMPSAT-2A, Elektro-L series and others, getting the images is, in my opinion, just the start! Like NOAA, EUMETSAT, ROSCOSMOS, KMA, and other … Delve Deeper “Software and Coding for Post Processing of Imagery” »
