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.
Standard sea-level conditions (SSL), [1] also known as sea-level standard (SLS), defines a set of atmospheric conditions for physical calculations. The term "standard sea level " is used to indicate that values of properties are to be taken to be the same as those standard at sea level, and is done to define values for use in general calculations.
With a temperature lapse rate of −6.5 °C (-11.7 °F) per km (roughly −2 °C (-3.6 °F) per 1,000 ft), the table interpolates to the standard mean sea level values of 15 °C (59 °F) temperature, 101,325 pascals (14.6959 psi) (1 atm) pressure, and a density of 1.2250 kilograms per cubic meter (0.07647 lb/cu ft).
The U.S. Standard Atmosphere is a static atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations. The model, based on an existing international standard, was first published in 1958 by the U.S. Committee on Extension to the Standard Atmosphere, and ...
World leaders in 2015 agreed to limit warming to well below 2 degrees C and also to aim for 1.5 degrees. But many countries are struggling to cut fossil fuels from their economies, and efforts ...
By the end of the 21st century, temperatures may increase to a level last seen in the mid-Pliocene. This was around 3 million years ago. [28]: 322 At that time, mean global temperatures were about 2–4 °C (3.6–7.2 °F) warmer than pre-industrial temperatures. The global mean sea level was up to 25 metres (82 ft) higher than it is today.
On Thursday, New Delhi nearly ranked among the world's top 10 when it topped out at 109 degrees (43 C), about 5 degrees shy of the all-time record high temperature for April there, which is 114.1 ...
If you suspect bed bugs due to getting bites at night or recent travel, get a certified canine bed bug inspection to find out if you have bed bugs and where they are hiding.” 10. Carpet Beetles
