A satellite orbiting hundreds of miles above Earth recently captured rare images of an atmospheric phenomenon that makes Antarctica glaciers appear to be smoking. The wisps of "sea smoke" blowing ...
The satellite images have pixel ground resolutions of under 0.5 meters, and overlapping images from different angles can be used to extract elevation data for DEMs. Based only on satellite position, there may be errors of several meters, but through ground control registration these can be reduced to point-to-point errors of 20 centimeters or ...
An iceberg larger than Rhode Island broke off from the Ronne ice shelf in Antarctica's Weddell Sea mid-May, and a satellite operated by European scientists captured the moment the massive piece of ...
Scientists used satellite imagery and data to analyze vegetation levels on the Antarctic Peninsula, a long mountain chain that points north to the tip of South America, and which has been warming ...
Some locations on free, publicly viewable satellite map services have such issues due to having been intentionally digitally obscured or blurred for various reasons of this. [1] For example, Westchester County, New York asked Google to blur potential terrorism targets (such as an amusement park, a beach, and parking lots) from its satellite ...
Post November 2017, satellite images showed that A-68 was slowly drifting northward, with a widening gap to the main shelf. The gap was approximately five kilometers (3.1 miles) wide and contained a thin layer of loose, floating ice and a cluster of more than 11 'smaller' bergs, one much larger than the others.
The need for satellite imagery from geostationary and polar-orbiting satellites over the Antarctic led to the formation of the AMRC. Today, the AMRC continues to create Antarctic satellite composites and conduct research with those composites and other observational data sets, such as those from UW-Madison’s AWS program.
While colder temperatures have been recorded at Vostok Station, Antarctica (minus 128.6 degrees on July 21, 1983) and Klink Station, Greenland (minus 93.3 degrees on Dec. 22, 1991), Oymyakon's ...
