Surface temperature is the temperature at a surface. Specifically, it may refer to: Near-surface air temperature, the temperature of the air near the surface of the Earth; Sea surface temperature, the temperature of water close to the ocean's surface
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 ...
For comparison, the sea surface skin temperature relates to the top 20 or so micrometres of the ocean's surface. The definition proposed by IPCC for sea surface temperature does not specify the number of metres but focuses more on measurement techniques: Sea surface temperature is "the subsurface bulk temperature in the top few metres of the ...
Thermophysical properties are characteristics that control the diurnal, seasonal, or climatic surface and subsurface temperature variations (or thermal curves) of a material. The most important thermophysical property is thermal inertia , which controls the amplitude of the thermal curve and albedo (or reflectivity ), which controls the average ...
Emissions from surface: Based on thermal emissions from the surface, Earth's effective surface temperature is about 16 °C (61 °F), [22]: 934 which is 34 °C (61 °F) warmer than Earth's overall effective temperature. Earth's surface temperature is often reported in terms of the average near-surface air temperature.
The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a shelter such as a Stevenson screen—a standardized, well-ventilated, white-painted instrument shelter. The thermometers should be positioned 1.25–2 m above the ground.
The science behind 'feels like' temperature. The answer to "feels like" temperature, according to the National Weather Service, has to do with wind, or wind chill to be more specific.
In science, a field is a physical quantity, represented by a scalar, vector, or tensor, that has a value for each point in space and time. [1] [2] [3] An example of a scalar field is a weather map, with the surface temperature described by assigning a number to each point on the map.
