NASA biosphere data are critical for understanding Earth's species diversity, climate regulation and change, and its ecosystem processes. Life within Earth’s biosphere consists of millions of species living in various types of biomes such as grassland, forest, desert, aquatic, and tundra areas. Biomes are often divided into numerous subtypes ...
Cryosphere. NASA has data on sea ice, glaciers, snow cover, and other frozen features that comprise Earth’s cryosphere and effect human activity and our planet. Earth is covered in nearly six million square miles (15 million square kilometers) of ice across its polar caps, glaciers, and ice sheets. NASA’s satellites and other scientific ...
Anthropogenic/Human Influenced Ecosystems. NASA’s Earth science data show the impact of humans on the planet through studying factors like nighttime lights, land cover, and agriculture. There are many causes of biodiversity loss, including deforestation, agricultural development, urbanization, pollution, and climate change.
Ecosystems. An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network ...
6 juin 2022 · Explore Learning Resources. NASA’s massive archive of Earth science data are free and open to any user for any purpose—but accessing, analyzing, visualizing, and applying these data requires a certain degree of knowledge about Earth observation data and how it is collected and optimized. Check out our catalog of learning resources to better ...
Find Data. Earth’s atmosphere is a thin veil of gas surrounding the planet. Although it only extends a few hundred kilometers above the surface, it contains a mixture of gases, such as oxygen and nitrogen, that are critical for life to exist. It distributes incoming solar radiation, protecting life from harmful ultraviolet radiation but also ...
Wetlands are a type of terrain where the land is permanently or seasonally saturated with water. Swamps and marshes are types of wetlands. Insects, waterfowl, fish, amphibians, and other animals often find a home in wetlands, creating a complex ecosystem that combines land-based and aquatic life. Wetlands help stabilize shorelines and provide a ...
Lightning is the electrical discharge between positively and negatively charged regions within clouds. Visually, lightning is comprised of bright flashes of light called strokes. The loud sound of thunder that accompanies lightning is a sonic shock wave produced by the rapid expansion of the air surrounding the lightning channel during the ...
Atmospheric Ozone. Atmospheric Ozone is one of the most important trace gases in our atmosphere that both benefits and harms life on Earth. High ground-level ozone amounts contribute to poor air quality, adversely affecting human health, agricultural productivity, and forested ecosystems. Ozone absorbs infrared radiation, and is most potent as ...
13 juin 1991 · Gases and solids injected into the stratosphere circled the globe for three weeks. Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns.
