Enhanced Mid-Latitude Tropospheric Column Ozone over East Asia: Coupled Effects of Stratospheric Ozone Intrusion and Anthropogenic Sources
We analyze tropospheric column ozone (TCO) data observed by satellite instruments over East Asia for 15 years (from 1995 to 2009), and investigate the relationship between enhanced TCO (E-TCO) and ozone intrusion from the stratosphere near the subtropical jet (STJ). A belt of E-TCO is observed at mid-latitude over East Asia throughout the year; the belt is located at latitudes approximately equ...
متن کاملObservation of ozone enhancement in the lower troposphere over East Asia from a space-borne ultraviolet spectrometer
We report observations from space using ultraviolet (UV) radiance for significant enhancement of ozone in the lower troposphere over central and eastern China (CEC). The recent retrieval products of the Ozone Monitoring Instrument (OMI) onboard the Earth Observing System (EOS) Aura satellite revealed the spatial and temporal variation of ozone distributions in multiple layers in the troposphere...
متن کاملPhotochemical roles of rapid economic growth and potential abatement strategies on tropospheric ozone over South and East Asia in 2030
A regional air quality simulation framework including the Weather Research and Forecasting modeling system (WRF), the Community Multi-scale Air Quality modeling system (CMAQ), and precursor emissions to simulate tropospheric ozone over South and East Asia is introduced. Concentrations of tropospheric ozone and related species simulated by the framework are validated by comparing with observatio...
متن کاملAnalysis of the summertime buildup of tropospheric ozone abundances over the Middle East and North Africa as observed by the Tropospheric Emission Spectrometer instrument
[1] We use the GEOS-Chem chemical transport model to interpret observations of tropospheric ozone from the Tropospheric Emission Spectrometer (TES) satellite instrument in summer 2005. Observations from TES reveal elevated ozone in the middle troposphere (500–400 hPa) across North Africa and the Middle East. Observed ozone abundances in the middle troposphere are at a maximum in summer and a mi...
متن کاملImpacts of the East Asian monsoon on lower tropospheric ozone over coastal South China
The impact of the East Asian monsoon (EAM) on climatology and interannual variability of tropospheric ozone (O3) over the coastal South China was investigated by analyzing 11 years of ozonesonde data over Hong Kong with the aid of Lagrangian dispersion modeling of carbon monoxide and calculation of an EAM index. It was found that the seasonal cycle of O3 in the lower troposphere is highly relat...
