  2. Cloud cover - Wikipedia

    en.wikipedia.org/wiki/Cloud_cover

    The average cloud cover of the Earth, 2005-2013. Colors range from blue (no clouds) to white (totally cloudy). [6] (click for more detail) Cloud cover values only vary by 3% from year-to-year averages, whereas the local, day-to-day variability in cloud amounts typically rises to 30% over the globe.

  3. Cloud top - Wikipedia

    en.wikipedia.org/wiki/Cloud_top

    View of clouds from above. The cloud top (or the top of the cloud) is the highest altitude of the visible portion of a cloud.It is traditionally expressed either in metres above the Earth (or planetary) surface, or as the corresponding pressure level in hectopascal (hPa, equivalent to the traditional but now obsolete millibar).

  4. CloudSat - Wikipedia

    en.wikipedia.org/wiki/CloudSat

    CloudSat is a Passivated NASA Earth observation satellite, which was launched on a Delta II rocket on April 28, 2006, and is awaiting disposal. It used radar to measure the altitude and properties of clouds, adding to the information on the relationship between clouds and climate to help resolve questions about global warming.

  5. Google Earth - Wikipedia

    en.wikipedia.org/wiki/Google_Earth

    Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography , and GIS data onto a 3D globe , allowing users to see cities and landscapes from various angles.

  6. ICESat-2 - Wikipedia

    en.wikipedia.org/wiki/ICESat-2

    The satellite orbits Earth at a speed of 6.9 kilometers per second (4.3 mi/s). [8] The ICESat-2 mission is designed to provide elevation data needed to determine ice sheet mass balance as well as vegetation canopy information. It will provide topography measurements of cities, lakes and reservoirs, oceans and land surfaces around the globe, in ...

  7. Advanced Spaceborne Thermal Emission and Reflection ...

    en.wikipedia.org/wiki/Advanced_Spaceborne...

    ASTER provides high-resolution images of Earth in 14 different bands of the electromagnetic spectrum, ranging from visible to thermal infrared light. The resolution of images ranges between 15 and 90 meters. ASTER data is used to create detailed maps of surface temperature of land, emissivity, reflectance, and elevation. [1]

  8. Earth observation satellite - Wikipedia

    en.wikipedia.org/wiki/Earth_observation_satellite

    An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others.

  9. Cloud height - Wikipedia

    en.wikipedia.org/wiki/Cloud_height

    The cloud height, more commonly known as cloud thickness or depth, is the distance between the cloud base and the cloud top. [1] It is traditionally expressed either in metres or as a pressure difference in hectopascal (hPa, equivalent to millibar ).
