PEOPLE AND PLACES
All over the world in different countries, cultures, tongues, and colors are people who have the same basic desire for happiness and respect from his fellow men. We are the same all over as members of the human race. If we honor each other's boundaries with propriety and consideration our voyage thru life can be rich in knowledge and friendship..........AMOR PATRIAE

Most air pollution is measures at a city level, but air quality can change by block, as well as hour by hour and from day to day. 
In order to better understand air quality on a more local level, Google Earth partnered with environmental sensor network firm Aclima to map air pollution across California, with the hopes of using the information to help build smarter, more sustainable cities. 
They used Google Street View cars equipped with air quality sensors, and are now sharing some of their findings for the three California regions they've mapped: The San Francisco Bay Area, Los Angeles, and California's Central Valley. 
In Los Angeles for example, the measurements indicate that traffic-chocked freeways, traffic on local streets and weather patterns that blow pollution inland all influence the patterns of air pollution.

The Nitogen Dioxide (NO2) scale indicates pollution levels, with blue indicating low NO2 levels, and yellow indicating high NO2 levels. A large percentage of air pollution emissions in San Francisco comes from vehicles like cars, trucks and construction equipment, and industrial sources like refineries and power plants
To conduct the analysis, the Street View cars drove 100,000 miles over the course of 4,000 hours for a three month period. 
Google Earth says scientists and air quality specialists can use this information to help local organizations, governments and regulators in identifying opportunities to achieve greater air quality improvement and solutions

ON MAP PROJECT 

Google Earth partnered with environmental sensor network firm Aclima to map air pollution across California. 
The air quality project, launched in 2015, has already driven 14,000 miles (22,000 km) around the US and has now released a prototype map online.
Earlier this year, the partners shared the first results of this effort with pollution levels throughout the city of Oakland.
They used Google Street View cars equipped with air quality sensors, and are now sharing a new set of findings for three California regions they've mapped: The San Francisco Bay Area, Los Angeles, and California's Central Valley.

Google Earth released heat maps showing Nitrogen Dioxide (NO2) levels across three regions.

The findings for San Francisco show that compared to Los Angeles, it is a higher density city. A large percentage of air pollution emissions in San Francisco comes from vehicles like cars, trucks and construction equipment, and industrial sources like refineries and power plants

In addition, weather conditions and topography can trap air pollution between the coast and the Sierra Nevada mountains, leading to chronic ozone and particulate matter levels that exceed public health standards. 
So far, Google Earth and Aclima have measures over one billion air quality data points, but the partners will conduct further measurements and now air quality scientists can request access to the data.  
The partners hope that the data helps reduce climate changing greenhouse gases and improve air quality for healthier living.

Interstate 5 and Interstate 99 are two major traffic corridors that run through the region, connecting Northern and Southern California, and traffic on these interstate, along with regional traffic and industry and agriculture, are sources of air pollution in the region
