英文摘要: Infrared radiative cooling of the thermosphere by carbon dioxide (CO 2, 15-μm) and by nitric oxide (NO, 5.3-μm) has been observed for 12-years by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument on the Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics satellite. For the first time we present a record of the two most important thermospheric infrared cooling agents over a complete solar cycle. SABER has documented dramatic variability in the radiative cooling on time scales ranging from days to the 11 year solar cycle. Deep minima in global mean vertical profiles of radiative cooling are observed in 2008-2009. Current solar maximum conditions, evidenced in the rates of radiative cooling, are substantially weaker than prior maximum conditions in 2002-2003 the observed changes in thermospheric cooling correlate well with changes in solar ultraviolet irradiance and geomagnetic activity during the prior maximum conditions. NO and CO2 combine to emit 7-×-1018 more Joules annually at solar maximum than at solar minimum. Key Points First record of thermospheric IR cooling rates over a complete solar cycle IR cooling in current solar maximum conditions much weaker than prior maximum Variability in thermospheric IR cooling observed on scale of days to 11 years ©2014 the Authors.
