Mid‐upper tropospheric methane in the high Northern Hemisphere: Spaceborne observations by AIRS, aircraft measurements, and model simulations
[1] Spaceborne measurements by the Atmospheric Infrared Sounder (AIRS) on the EOS/ Aqua satellite provide a global view of the methane (CH4) distribution in the mid‐upper troposphere (MUT‐CH4). The focus of this study is to examine the spatiotemporal variation of MUT‐CH4 in the high Northern Hemisphere (HNH) using AIRS retrievals, aircraft measurements, and simulations from a forward chemistry‐...

15 صفحه اولThe Evaluation of Tropospheric Ozone Formation in the Downwind of the South Pars Industrial Zone
Hydrocarbon Processing Industries (HPIs) emit large amounts of highly reactive hydrocarbons and Nitrogen Oxides to the atmosphere. Such simultaneous emissions of ozone precursors result in rapid and high yields ozone (O3) formation downwind. The climate of the Middle East has been shown to be favorable for O3 formation in summer. There are also vast activities in processing oil and gas in this ...
متن کاملContribution of stratospheric ozone to the interannual variability of tropospheric ozone in the northern extratropics
[1] We examined the role of variability in the input of stratospheric ozone on the interannual variability of tropospheric ozone in the northern extratropics using correlations of monthly ozone anomalies for the lower stratosphere and the troposphere. We used output from a multiyear simulation of the NASA Goddard Space Flight Center (GSFC) Chemistry and Transport Model (CTM), and evaluated mode...
متن کاملTropospheric ozone over the North Pacific from ozonesonde observations
[1] As part of the Transport and Chemical Evolution over the Pacific (TRACE-P) mission, ozonesondes were used to make ozone vertical profile measurements at nine locations in the North Pacific. At most of the sites there is a multiyear record of observations. From locations in the western Pacific (Hong Kong; Taipei; Jeju Island, Korea; and Naha, Kagoshima, Tsukuba, and Sapporo, Japan), a site i...
