abstract = {This study quantifies the present-day global and regional
distributions (2010–2014) and trends (2000–2014) for
five ozone metrics relevant for short-term and long-term
human exposure. These metrics, calculated by the
Tropospheric Ozone Assessment Report, are: 4th highest daily
maximum 8-hour ozone (4MDA8); number of days with MDA8 > 70
ppb (NDGT70), SOMO35 (annual Sum of Ozone Means Over 35 ppb)
and two seasonally averaged metrics (3MMDA1; AVGMDA8). These
metrics were explored at ozone monitoring sites worldwide,
which were classified as urban or non-urban based on
population and nighttime lights data.Present-day
distributions of 4MDA8 and NDGT70, determined predominantly
by peak values, are similar with highest levels in western
North America, southern Europe and East Asia. For the other
three metrics, distributions are similar with North–South
gradients more prominent across Europe and Japan. Between
2000 and 2014, significant negative trends in 4MDA8 and
NDGT70 occur at most US and some European sites. In
contrast, significant positive trends are found at many
sites in South Korea and Hong Kong, with mixed trends across
Japan. The other three metrics have similar, negative trends
for many non-urban North American and some European and
Japanese sites, and positive trends across much of East
Asia. Globally, metrics at many sites exhibit
non-significant trends. At $59\%$ of all sites there is a
common direction and significance in the trend across all
five metrics, whilst 4MDA8 and NDGT70 have a common trend at
$~80\%$ of all sites. Sensitivity analysis shows AVGMDA8
trends differ with averaging period (warm season or annual).
Trends are unchanged at many sites when a 1995–2014 period
is used; although fewer sites exhibit non-significant
trends. Over the longer period 1970–2014, most Japanese
sites exhibit positive 4MDA8/SOMO35 trends. Insufficient
data exist to characterize ozone trends for the rest of Asia
and other world regions.},
