Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. [2] Smoke from fires in the western United States such as Colorado and Utah have also been monitored. El Niño and its effects on weather are
Winter Storm Cora is spreading a wintry mess of snow and ice across much of the South, including Atlanta and Charlotte. On this page, you'll find maps below that will help to track the storm.
The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
Remotely sensed multi- and hyperspectral images can be used for assessing biodiversity at different scales. Since the spectral properties of different plants species are unique, it is possible to get information about properties that relates to biodiversity such as habitat heterogeneity, spectral diversity and plant functional trait.

6- monthly NDVI average for Australia, 1 Dec 2012 to 31 May 2013 [1]. A vegetation index (VI) is a spectral imaging transformation of two or more image bands designed to enhance the contribution of vegetation properties and allow reliable spatial and temporal inter-comparisons of terrestrial photosynthetic activity and canopy structural variations.
Since then, radar has become a widely used method for studying migrating organisms. Early radar technologies, such as WSR-57 (Weather Surveillance Radar - 1957), have been replaced by the Next Generation Weather Radar program which was installed in segments during the 1990s. Also known as WSR-88D (Weather Surveillance Radar 88 Doppler), NEXRAD ...
The goal of this project was to produce a satellite for earth observation by way of a Synthetic Aperture Radar, which is an advanced radar sensor and powerful microwave instrument capable of producing high quality images of the Earth during day or night and across a wide range of weather conditions including cloud cover, smoke, and haze.

The Kasta 2E (NATO: Flat Face E, alternative name Casta 2E) is a modern Russian radar system. The development of the Kasta 2E surveillance radars was initiated in the former Soviet Union . Its primary objective is to overcome deficiencies or to satisfy the demand in low-level surveillance.
