  32 outdoor

  To this end, Aclima has been 33 collaborating with Google’s Street
View system, resulting in maps such as the one below。 Davida Herzl,
Aclima’s boss, says they have, as expected, revealed pollution highs
on days when San Francisco’s transit workers went on strike and the
city’s 34 inhabitants were forced to take to their cars。 Conversely,
“cycle to work” days have done their job by 35 creating pollution lows。

ca88 1

  Since the 1940s, southern California has had a reputation for
smog。 Things are not as bad as they once were but, according to the
American Lung Association, Los Angeles is still the worst city in the
United States for levels of 26 。Gazing down on the city from the Getty
Center, an art museum in the Santa Monica Mountains, one would find
the view of the Pacific Ocean blurred by the haze(霾)。Nor is the
state’s bad air 27 to its south。 Fresno, in the central valley, comes
top of the list in America for year-round pollution。 Residents’ hearts
and lungs are affected as a 28 。

  Again, Google has acted as a guinea pig。 It has been testing
Aclima’s technology in its offices for the past two years, crunching
through more than half a billion data points a day on the air quality
within them。 The result, according to Ms Herzl, is the world’s
largest pollution-related database on indoor environments。

  Without wind and other weather to move them on, these data show,
indoor levels of many nasties can be between two and five times those
outside。 The Googleplex is in Silicon Valley—a relatively clean part of
the state。 If such ratios also apply on a smoggy day in LA, watch
out。

  All of which, combined with California’s reputation as the home of
technological 29 innovation, makes the place ideal for developing and
testing systems designed to monitor pollution in 30 detail。 And that is
just what Aclima, a fledgling firm in San Francisco, has been doing
over the past few months。 It has been trying out arrays of monitoring
stations, some of them mobile, that are 31 intended to yield
minute-to-minute maps of 32 outdoor air pollution。 Such stations will
also be able to keep an eye on what is going on inside buildings,
including offices。

  31 intended

  The stations in Aclima’s arrays are triangular and measure 20cm
along a side。 Each contains 12 off-the-shelf sensors that detect
pollutants such as ozone, carbon monoxide and methane, as well as the
small particles of which smog is composed。 They also monitor basic data
such as temperature and humidity, which affect how pollution forms and
lingers。 The elements of an array may be fixed and spaced according to
what exactly they are trying to measure。 Or they can be attached to
vehicles, so that entire roads can be sampled routinely。

  33 collaborating

  Aclima has already, at Google’s expense, mapped 20,000km
(12,000 miles) of roads in the Bay Area this way。 It plans to
produce a detailed map of the air quality of California’s most populous
regions—those around Los Angeles, San Francisco and the Central
Valley—before the year is out。 It will then move on to the rest of
America and (Ms Herzl hopes) beyond。 For such outdoor work, most of
its customers are likely to be charitable foundations or governments。
But Aclima hopes to make money from the private sector as well, by
measuring pollution levels indoors。

  29 innovation

  作者:兰州学校新东方李逸飞老师

  SINCE the 1940s, southern California has had a reputation for
smog。 Things are not as bad as once they were but, according to the
American Lung Association, a health group, Los Angeles is still the
worst city in the United States for levels of 26 ozone, nitrogen
oxides, hydrocarbons and carbon monoxide。 Gazing down on the city from
the Getty Centre, an art museum in the Santa Monica Mountains, haze
can blot out the view of the Pacific Ocean。 Nor is the state’s bad air
27 restricted to its south。 Fresno, in the central valley, comes top
of the list in America for year-round particulate pollution。 Residents’
hearts and lungs are strained as a 28 consequence。
