The stratosphere (/ ˈ s t r æ t ə ˌ s f ɪər,-t oʊ-/) is the second-lowest layer of the atmosphere of Earth, located above the troposphere and below the mesosphere. [ 2 ] [ 3 ] The stratosphere is composed of stratified temperature zones, with the warmer layers of air located higher (closer to outer space ) and the cooler layers lower ...
Projected global surface temperature changes relative to 1850–1900, based on CMIP6 multi-model mean changes. The IPCC Sixth Assessment Report defines global mean surface temperature (GMST) as the "estimated global average of near-surface air temperatures over land and sea ice, and sea surface temperature (SST) over ice-free ocean regions, with changes normally expressed as departures from a ...
The Moderate-Resolution Imaging Spectroradiometer aboard the Terra satellite can detect thermal hot spots associated with wildfires, volcanoes, and industrial hot spots. [19] The Atmospheric Infrared Sounder on the Aqua satellite, launched in 2002, uses infrared detection to measure near-surface temperature. [20]
The stratosphere is the second-lowest layer of Earth's atmosphere. It lies above the troposphere and is separated from it by the tropopause . This layer extends from the top of the troposphere at roughly 12 km (7.5 mi; 39,000 ft) above Earth's surface to the stratopause at an altitude of about 50 to 55 km (31 to 34 mi; 164,000 to 180,000 ft).
FEMA's index calculates wildfire risk based on a community's expected annual fire losses, assigning ratings from very low to very high. A "very high" risk area means it has significantly higher ...
The department’s National Interagency Fire Center, which released the maps, points out that much of the U.S. received below normal precipitation in January and that drought had increased ...
These layers are the troposphere, stratosphere, mesosphere, and thermosphere. The troposphere is the lowest of the four layers and extends from the surface of the Earth to about 11 km (6.8 mi) into the atmosphere, where the tropopause (the boundary between the troposphere stratosphere) is located. The width of the troposphere can vary depending ...
In Wyoming, about 69% of properties could be at "major" risk of a wildfire in the next 30 years, and Colorado has the next highest figure, with 53% facing "major" risk.
