英文摘要: We show measurements of middle atmospheric water vapor as measured by two ground-based Water Vapor Millimeter-wave Spectrometer instruments and three satellite-based instruments: the Aura Microwave Limb Sounder, the Atmospheric Chemistry Experiment (ACE), and the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). We also show CH4 measurements from the MIPAS and ACE instruments and use these to help interpret the H2 O variations. We find that interannual changes in stratospheric H2 O of ~0.5 ppmv, observed from Table Mountain, California, at 26 km and 40 km from 2010 to 2012, are caused primarily by dynamically driven changes in CH 4 during this period. The interannual variations in H2 O observed over Mauna Loa, Hawaii, are shown to be quite similar to the average variations observed over 50°S-50°N in the lower mesosphere; thus, we conclude that a single ground-based microwave instrument can provide a useful estimate of interannual globally averaged lower mesospheric H2 O variations, even when such changes are as small as ~0.2-0.3 ppmv. We find that the increase of ~0.2-0.3 ppmv in H2 O in the lower mesosphere since 2006 is qualitatively consistent with an increase in tropical tropopause temperature since around 2001. Key Points H2 O has increased by 0.2-0.3 ppmv in the lower mesosphere since 2006 Variations observed at Mauna Loa and globally at the stratopause are similar CH4 changes account for the increase in H2 O from 2010 to 2011 at Table Mountain ©2013.
