Sensitivity of midnineteenth century tropospheric ozone to atmospheric chemistry-vegetation interactions by Hollaway, M., Arnold, S., Collins, Bill, Folberth, G., Rap, A.

“…We use an Earth System model (HadGEM2-ES) to investigate the sensitivity of midnineteenth century tropospheric ozone to vegetation distribution and atmospheric chemistry-vegetation interaction processes. We conduct model experiments to isolate the response of midnineteenth century tropospheric ozone to vegetation cover changes between the 1860s and present day and to CO 2 -induced changes in isoprene emissions and dry deposition over the same period. …”

Evaluation of preindustrial to present-day black carbon and its albedo forcing from Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) by Lee, Y., Lamarque, J., Flanner, M., Jiao, C., Shindell, D., Berntsen, T., Bisiaux, M., Cao, J., Collins, W., Curran, M., Edwards, Peter, Faluvegi, G., Ghan, S., Horowitz, L., McConnell, J., Ming, J., Myhre, G., Nagashima, T., Naik, V., Rumbold, S., Skeie, R., Sudo, K., Takemura, T., Thevenon, F., Xu, B., Yoon, J.

“…As part of the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP), we evaluate the historical black carbon (BC) aerosols simulated by 8 ACCMIP models against observations including 12 ice core records, long-term surface mass 5. concentrations and recent Arctic BC snowpack measurements. …”

Numerical studies of urban heat island in greater Kuala Lumpur, Malaysia : from surface and boundary layer conditions to local air pollution by Ooi, Chel Gee

“…The model evaluation has realistically discovered that WRF is able to produce good approximation of the near-surface weather condition and fairly reasonable vertical boundary layer profiles. However, the atmospheric chemistry composition of the local surface pollutants is greatly underestimated. …”
