MODIS has now been replaced by the VIIRS, [citation needed] which first launched in 2011 aboard the Suomi NPP satellite. The MODIS instruments were built by Santa Barbara Remote Sensing. [ 1 ] They capture data in 36 spectral bands ranging in wavelength from 0.4 μm to 14.4 μm and at varying spatial resolutions (2 bands at 250 m, 5 bands at ...
An image of global sea surface temperatures acquired from the NOAA/ AVHRR satellite. The Advanced Very-High-Resolution Radiometer (AVHRR) instrument is a space-borne sensor that measures the reflectance of the Earth in five spectral bands that are relatively wide by today's standards.
VIIRS has a swath width of 3060 km at the satellite's average altitude of 829 km. [3] This swath width is able to provide complete coverage of Earth across the day. The VIIRS instrument can collect data in 22 different spectral bands of the electromagnetic spectrum, in the wavelengths between 0.412 μm and 12.01 μm. [ 3 ]
NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
An example is TerraSAR-X, which is a German Earth-Observation satellite. Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to provide multiple imaging modes for recording images with different swath width, resolution and polarizations, see the figure for more details.
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.
The Earth-observing ERS-2 satellite first launched on April 21, 1995, and it was the most sophisticated satellite of its kind at the time to be developed and launched by Europe.
Terra (EOS AM-1) is a multi-national scientific research satellite operated by NASA in a Sun-synchronous orbit around the Earth.It takes simultaneous measurements of Earth's atmosphere, land, and water to understand how Earth is changing and to identify the consequences for life on Earth. [1]
