  2. Outgoing longwave radiation - Wikipedia

    en.wikipedia.org/wiki/Outgoing_longwave_radiation

    Outgoing longwave radiation (OLR) is the longwave radiation emitted to space from the top of Earth's atmosphere. [1]: 2241 It may also be referred to as emitted terrestrial radiation. Outgoing longwave radiation plays an important role in planetary cooling. Longwave radiation generally spans wavelengths ranging from 3–100 micrometres (μm).

  3. Earth's energy budget - Wikipedia

    en.wikipedia.org/wiki/Earth's_energy_budget

    Earth's energy imbalance (EEI) Earth's energy budget (in W/m 2) determines the climate. It is the balance of incoming and outgoing radiation and can be measured by satellites. The Earth's energy imbalance is the "net absorbed" energy amount and grew from +0.6 W/m 2 (2009 est. [8]) to above +1.0 W/m 2 in 2019. [23]

  4. Greenhouse effect - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_effect

    [15]: 2251 Informally, longwave radiation is sometimes called thermal radiation. Outgoing longwave radiation (OLR) is the radiation from Earth and its atmosphere that passes through the atmosphere and into space. The greenhouse effect can be directly seen in graphs of Earth's outgoing longwave radiation as a function of frequency (or wavelength).

  5. Water vapor windows - Wikipedia

    en.wikipedia.org/wiki/Water_vapor_windows

    The resultant temperature is -18.7 °C. Compared to +14.5 °C, the average worldwide temperature of the Earth's surface is 33 °C cooler. [5] Thus, the Earth's surface is up to 33 °C warmer than it would be without the atmosphere. Moreover, the observation of longwave radiation demonstrates that the greenhouse effect exists in the Earth's ...

  6. Cloud feedback - Wikipedia

    en.wikipedia.org/wiki/Cloud_feedback

    Details of how clouds interact with shortwave and longwave radiation at different atmospheric heights [17]. Clouds have two major effects on the Earth's energy budget: they reflect shortwave radiation from sunlight back to space due to their high albedo, but the water vapor contained inside them also absorbs and re-emits the longwave radiation sent out by the Earth's surface as it is heated by ...

  7. Carrington Event - Wikipedia

    en.wikipedia.org/wiki/Carrington_Event

    Severe damage to telegraph stations. Part of solar cycle 10. The Carrington Event was the most intense geomagnetic storm in recorded history, peaking on 1–2 September 1859 during solar cycle 10. It created strong auroral displays that were reported globally and caused sparking and even fires in telegraph stations. [1]

  8. Paleoclimatology - Wikipedia

    en.wikipedia.org/wiki/Paleoclimatology

    Paleoclimatology (British spelling, palaeoclimatology) is the scientific study of climates predating the invention of meteorological instruments, when no direct measurement data were available. [1] As instrumental records only span a tiny part of Earth's history, the reconstruction of ancient climate is important to understand natural variation ...

  9. Miyake event - Wikipedia

    en.wikipedia.org/wiki/Miyake_event

    A Miyake event is an observed sharp enhancement of the production of cosmogenic isotopes by cosmic rays. It can be marked by a spike in the concentration of radioactive carbon isotope 14. Cl in ice cores, which are all independently dated. At present, five significant events are known (7176 BCE, 5259 BCE, 660 BCE, 774 CE, 993 CE) for which the ...
