| Zusammenfassung |
| A global climatology of tropospheric and stratospheric column ozone is
derived by combining six years of Aura Ozone Monitoring Instrument (OMI) and
Microwave Limb Sounder (MLS) ozone measurements for the period October 2004
through December 2010. The OMI/MLS tropospheric ozone climatology exhibits
large temporal and spatial variability which includes ozone accumulation
zones in the tropical south Atlantic year-round and in the subtropical
Mediterranean/Asia region in summer months. High levels of tropospheric
ozone in the Northern Hemisphere also persist in mid-latitudes over the
eastern part of the North American continent extending across the Atlantic
Ocean and the eastern part of the Asian continent extending across the
Pacific Ocean. For stratospheric ozone climatology from MLS, largest column
abundance is in the Northern Hemisphere in the latitude range
70° N–80° N in February–April and in the Southern Hemisphere around
40° S–50° S during August–October. Largest stratospheric ozone lies
in the Northern Hemisphere and extends from the eastern Asian continent
eastward across the Pacific Ocean and North America. With the advent of many
newly developing 3-D chemistry and transport models it is advantageous to
have such a dataset for evaluating the performance of the models in relation
to dynamical and photochemical processes controlling the ozone distributions
in the troposphere and stratosphere. The OMI/MLS gridded ozone climatology
data are made available to the science community via the NASA Goddard Space
Flight Center ozone and air quality website http://ozoneaq.gsfc.nasa.gov/. |
