Tropospheric ozone(O3)is a trace gas of great significance for air quality and climate *** recent years,due to the extensive implementation of emission reduction policies,the concentration of fine particulate matter in many countries has decreased significantly^([1]).In contrast,the global ground-level O3 concentration has increased by approximately 0.25 ppbv/a^([2]).Research shows that developed countries are experiencing a rebound in O3 levels while developing countries are facing more severe O3 pollution problems^([3,4]).Therefore,the prevention and control of O3 pollution is the top priority at this stage and will play a vital role in the longterm improvement of air quality.

A regional chemical transport model, RAMS-CMAQ, was employed to assess the impacts of biosphere–atmosphere CO2 exchange on seasonal variations in atmospheric CO2 concentrations over East Asia. Simulated CO2 concentrations were compared with observations at 12 surface stations and the comparison showed they were generally in good agreement. Both observations and simulations suggested that surface CO2 over East Asia features a summertime trough due to biospheric absorption, while in some urban areas surface CO2 has a distinct summer peak, which could be attributed to the strong impact from anthropogenic emissions. Analysis of the model results indicated that biospheric fluxes and fossil-fuel emissions are comparably important in shaping spatial distributions of CO2 near the surface over East Asia. Biospheric flux plays an important role in the prevailing spatial pattern of CO2 enhancement and reduction on the synoptic scale due to the strong seasonality of biospheric CO2 flux. The elevation of CO2 levels by the biosphere during winter was found to be larger than 5ppm in North China and Southeast China, and during summertime a significant depletion( 7 ppm) occurred in most areas,except for the Indo-China Peninsula where positive bioflux values were found.

High values of ozone(O_(3))occur frequently in the dry spring season;thus,understanding the evolution characteristics of volatile organic compounds(VOCs)in spring is of great significance for preventing O_(3)*** this study,a total of 101 VOCs from April 16 to May 21,2019,were quantified using an online gas chromatography mass spectrometer/flame ionization detector(GCMS/FID).The results indicated that the observed concentration of total VOCs(TVOCs)was 30.4±17.0 ppbv,and it was dominated by alkanes(44.3%),followed by oxygenated VOCs(OVOCs)(17.4%),halocarbons(12.7%),aromatics(9.5%),alkenes(8.2%),acetylene(5.3%)and carbon disulfide(2.5%).The average mixing ratio of VOCs showed obvious diurnal variation(high at night,low during daytime).We conducted a source apportionment study based on 32 major VOCs using positive matrix factorization(PMF),and coal+biomass burning(25.2%),diesel exhaust(16.0%),gasoline exhaust+evaporation(17.4%),secondary+long-lived species(16.7%),biogenic sources(4.3%),industrial emissions(9.3%)and solvent use(11.2%)were identified as major sources of *** addition to local emissions,most of the atmospheric VOCs were derived from long-distance air masses(65.7%),and the average mixing ratio of VOCs in the northwest direction was 29.4 *** with the results of the potential source contribution function(PSCF)indicate that research should focus on the local emissions of combustion,transportation sources and solvents usage to control atmospheric ***,transmission of the northwest air mass is an important component that cannot be ignored during spring in Beijing.

High loads of ground-level ozone have occurred with the implementation of the Air Pollution Prevention and Control Action ***,the long temporal variation in precursor nonmethane hydrocarbons(NMHCs)has rarely been *** this study,we examined the evolution of NMHCs in Beijing based on ambient measurements from 2000 to *** results indicated that the annual variation of ambient NMHCs during 2000 and 2019 could be divided into two *** mixing ratios of NMHCs rapidly rose during 2000 and 2009(1.76 ppbv/year)but exhibited a downward trend from 2009 to 2019 at rate of 0.80 ppbv/***,the notable decrease in alkenes and aromatics after 2009 led to a sharp decrease in the propylene-equivalent concentration(PEC)(-0.80 ppbv/year).Implementation of emission reduction measures in Beijing have effectively reduced the contribution of vehicle-related sources,but the contribution of solvent usage and fuel consumption increased,which will become the focus of VOC control in Beijing in the future.
