Users can also compare the air quality levels of their city with other global cities to see how they differ. Air Quality App allows you to compare the pollution levels of various cities . This duo’s cleaning products come as a boon to India’s polluted lakes.

Air pollution is typically seen as a problem that affects entire cities or regions. But a new study shows that air quality can vary tremendously within a city — even block by block. The unexpected finding suggests that it might be possible for local authorities to pinpoint pollution hot spots that would otherwise go undetected — and help citizens avoid living in or traveling through those areas.

For the study, published last week in the journal of Environment Science & Technology, researchers from the Environmental Defense Fund (EDF) and the University of Texas tracked two Google Street View cars rigged with air quality monitoring equipment as they drove throughout Oakland, Calif.

The vehicles measured the levels of black carbon, nitric oxide, and nitrogen dioxide in the air, collecting a total of 3 million data points during the yearlong study.

The results showed that traffic, time of day, and other variables create dramatic shifts in pollution levels near highways, bridges, and even fast food restaurants, adding to the "invisible threat" that has been linked to asthma, heart disease, and strokes.

The data was used to create detailed interactive maps featuring red, orange, and yellow dots to indicate levels of pollution at particular locations. The colors often shifted with traffic and at different times of the day, week, and year. Pollution levels varied as much as five times from block to block, says study co-author Dr. Steven Hamburg, chief scientist at the EDF.

'Plankton explosion' turns Istanbul's Bosphorus turquoise

  'Plankton explosion' turns Istanbul's Bosphorus turquoise A sudden change in the colour of the Bosphorus Strait that divides the continents of Europe and Asia in Turkey's largest city Istanbul has surprised residents, with scientists putting it down to a surge in a species of plankton across the Black Sea. The sudden transformation of the usually blue waters of the Bosphorus to a milky turquoise since the weekend had alarmed some residents.Some took to social media to express fears that there had been a pollution spill while others even suggested it could be linked to an earthquake that rocked the Aegean region on Monday afternoon.

"We have to understand the patterns better and we believe the Oakland data and the learnings from that and the subsequent cities we map will be able to highlight and illustrate exactly how to do that," Hamburg says.

The study will soon expand to other cities. And Aclima, the San Francisco-based environmental tech company that equipped the cars, is exploring the possibility of putting its air-sampling systems on city buses and delivery trucks and at stationary locations in major cities to gather up-to-date air pollution measurements.

The data could be incorporated into Google Maps and other map apps so users could simply open their smartphones to know which hotspots to avoid. The information could make it possible for users to select a running route with clean air, for example, or focus their apartment searches to areas with low pollution.

"Doing the science is a means, not the goal," Hamburg says. "Our goal is to ensure that the data becomes available and is used and is affecting people in a real substantive and positive way."

It’s June. California Is Still Covered in Snow .
The summer solstice is just around the corner, but someone forgot to tell California’s snowpack. After years of wallowing in drought, this winter walloped California’s Sierra Nevada mountains in a major, record-setting way. And while the calendar says summer, winter still has its grips on the granite spine of the Sierras. NASA Earth Observatory released satellite imagery on Thursday that shows what a difference a year makes. Snowpack is at 170 percent of normal when averaged across the state and some areas are reporting way higher totals than that, according to the California Department of Water Resources. Alpine Meadows, located just west of Lake Tahoe, reported 288 inches of snow on the ground (no, that’s not a typo) as of early June. Deep green hues of healthy vegetation also extend down the Sierra Nevada western slope, another benefit of all that precipitation.

California, you’ll may recall, was in an epic drought until this winter helped bust it in a big way. Beyond making skiers happy, the massive amounts of snow at high elevations and rain at low elevations helped fill reservoirs that were dangerously low.
