Early studies of plant response to ozone (O3) utilized concentration-based metrics, primarily
by summarizing the commonly monitored hourly average data sets. Research with the O3 …

Tropospheric ozone (O3) was first determined to be phytotoxic to grapes in southern
California in the 1950s. Investigations followed that showed O3 to be the cause of foliar …

China suffered from serious and elevated ozone (O 3) pollution during 2014–2020. O 3
exposure increased with W126, a biologically based cumulative exposure index, at a rate of …

Energy is an integral part of society. The major US energy sources of fossil fuels (coal, oil,
natural gas); biofuels (ethanol); and wind are concentrated in grassland ecosystems of the …

A one‐dimensional canopy model was developed to study photochemical processes inside
and above a mixed deciduous forest in southern Ontario. The Eulerian model made use of …

Biospheric ozone has become a widely distributed air pollutant, and a growing body of
research indicates that ozone impacts forest health and productivity. Ozone effects are …

While moving towards a flux-based approach, exposure-based ozone metrics are still a
practical measure for summarising ambient air quality. Ozone hourly concentrations for the …

The mixing ratios of surface O 3 were measured at St. John's College, Agra, an urban and
traffic influenced area for the period of 2000–2002. The monthly averaged O 3 mixing ratios …

Located in the transitional region between the Sichuan Basin (SCB) and Qinghai-Tibetan
Plateau (QTP), the West China Rain Zone (WCRZ) is a large-scale ecotone and partially …

The crowns of five canopy dominant black cherry (Prunus serotina Ehrh.), five white ash
(Fraxinus americana L.), and six red maple (Acer rubrum L.) trees on naturally differing …
