  2. Troposphere - Wikipedia

    en.wikipedia.org/wiki/Troposphere

    At the middle latitudes, tropospheric temperatures decrease from an average temperature of 15 °C (59 °F) at sea level to approximately −55 °C (−67 °F) at the tropopause. At the equator , the tropospheric temperatures decrease from an average temperature of 20 °C (68 °F) at sea level to approximately −70 to −75 °C (−94 to −103 ...

  3. Tropopause - Wikipedia

    en.wikipedia.org/wiki/Tropopause

    The troposphere contains the boundary layer, and ranges in height from an average of 9 km (5.6 mi; 30,000 ft) at the poles, to 17 km (11 mi; 56,000 ft) at the Equator. [ 3 ] [ 4 ] In the absence of inversions and not considering moisture , the temperature lapse rate for this layer is 6.5 °C per kilometer, on average, according to the U.S ...

  4. Microwave Sounding Unit temperature measurements - Wikipedia

    en.wikipedia.org/wiki/Microwave_Sounding_Unit...

    TMT and TLT represent the altitude range computed lower troposphere temperature calculated using an atmospheric model as discussed below. The T4 or TLS channel in representative of the temperature in the lower stratosphere with a peak weighting function at around 17 km above the Earth surface. Calculation of lower troposphere temperature

  5. Satellite temperature measurement - Wikipedia

    en.wikipedia.org/wiki/Satellite_temperature...

    Comparison of ground-based measurements of near-surface temperature (blue) and satellite based records of mid-tropospheric temperature (red: UAH; green: RSS) from 1979 to 2010. Trends plotted 1982-2010.

  6. Tropospheric propagation - Wikipedia

    en.wikipedia.org/wiki/Tropospheric_propagation

    Tropospheric ducting is a type of radio propagation that tends to happen during periods of stable, anticyclonic weather. In this propagation method, when the signal encounters a rise in temperature in the atmosphere instead of the normal decrease (known as a temperature inversion), the higher refractive index of the atmosphere there will cause the signal to be bent.

  7. Weak temperature gradient approximation - Wikipedia

    en.wikipedia.org/wiki/Weak_temperature_gradient...

    In atmospheric science, the weak temperature gradient approximation (WTG) is a theoretical framework used to simplify the equations governing tropical atmospheric dynamics and circulation. The WTG approximation assumes that free tropospheric temperature in the tropics has negligible horizontal (and temporal) gradients compared to its vertical ...

  8. UAH satellite temperature dataset - Wikipedia

    en.wikipedia.org/wiki/UAH_satellite_temperature...

    Some discrepancies between the UAH temperature measurements and temperatures measured by other groups remain, with (as of 2019) the lower troposphere temperature trend from 1979-2019 calculated as +0.13 °C/decade by UAH, [7] [8] and calculated at +0.208 °C/decade by RSS.
