Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust.
Google Earth is a 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. Users can explore the globe by entering addresses and ...
Earth observations satellites provide information for research subjects that benefit from looking at Earth’s surface from above (such as meteorology, oceanography, terrestrial ecology, glaciology, atmospheric science, hydrology, geology, and many more). Types of sensors on these satellites include passive and active remote sensors
Berkeley Earth is a Berkeley, California -based independent 501 (c) (3) non-profit focused on land temperature data analysis for climate science. Berkeley Earth was founded in early 2010 (originally called the Berkeley Earth Surface Temperature project) to address the major concerns from outside the scientific community regarding global warming ...
Earth observation. [1] Earth observation ( EO) is the gathering of information about the physical, chemical, and biological systems of the planet Earth. [2] It can be performed via remote-sensing technologies ( Earth observation satellites) or through direct-contact sensors in ground-based or airborne platforms (such as weather stations and ...
Global surface temperature (GST) refers to the average temperature of Earth 's surface. It is determined nowadays by measuring the temperatures over the ocean and land, and then calculating a weighted average. The temperature over the ocean is called the sea surface temperature. The temperature over land is called the surface air temperature.
Natural Earth is a public domain map dataset available at 1:10 million (1 cm = 100 km), 1:50 million, and 1:110 million map scales. [ clarification needed ] Natural Earth's data set contains integrated vector and raster mapping data.
Earth Observing System. The Earth Observing System ( EOS) is a program of NASA comprising a series of artificial satellite missions and scientific instruments in Earth orbit designed for long-term global observations of the land surface, biosphere, atmosphere, and oceans. Since the early 1970s, NASA has been developing its Earth Observing ...
