That led a pair of researchers to publish a new perspective piece in the journal Science today calling for a multidisciplinary push to better characterize these microbes and determine how they might be making wildfire smoke even worse for human lungs.
Drawing crowdsourced data from air quality sensors it sells to the public—ranging between $200 and $300—PurpleAir builds maps that show in real time just how bad a neighborhood like mine is suffering from particulate matter (PM) 2.5 pollution, the particles that make up wildfire smoke.
Courtesy of NOAASo if you’re looking at the HRRR-Smoke map, on that same left-hand menu, click on “Near Surface Smoke.” This gives you smoke concentrations at about 8 meters off the ground, which are indicated on a light-blue-to-purple color scale at top right on the map.
Last year NIWA air quality scientist Dr Ian Longley launched the Arrowtown project that included some outdoor monitoring and indoor air quality monitoring by people in their homes.
ACE2, which stands for angiotensin-converting enzyme 2, is a protein that sits on the surface of many types of cells in the human body, including in the heart, gut, lungs, and inside the nose.
Scientists still have much to learn about Covid-19, but, says Jessica McCarty, a geographer and fire scientist at Miami University, “We know that there's linkages between people who live in highly-polluted areas and their likelihood of getting any type of respiratory illness, as well as viral infections.” Smog from cars, for instance, remains a major threat to human health.
After almost six weeks of monitoring air quality during Level 3 and 4 lockdown restrictions, scientist Dr Ian Longley is now asking people to record where and when woodsmoke is affecting their health and lives.
The bushfires also caused a spike in carbon monoxide readings earlier in the year and last month NIWA scientists documented ash deposits on the South Island glaciers originating from the Australian fires.
The site, which opened in November after three years of construction, is meant to adapt to emerging security threats, and imparts the lessons of recent traumas like the attack on the American diplomatic compound in Benghazi, Libya.
The 104-floor building, the tallest in the US (1,776 feet not including its antenna), is, too, a story of despair and resilience and glamour.WIRED's New York offices are located in the building, which is home to Conde Nast's headquarters.
"I took a lot of the photographs from my driveway, essentially." The hard work of local firefighters saved the house, and Cooley continued photographing the aftermath of the fire, which eventually consumed over 7,000 acres, becoming one of the largest in Los Angeles history.
Smoke from home fires in winter can be smelt across our towns, causing irritation and annoyance to some, reducing visibility, and frequently causing air quality to exceed the National Environmental Standard. Although we don’t monitor smog directly, the levels of smoke are indicated by networks of air quality monitors operated by regional councils.
On that day, huge plumes of smoke drifted over North America and Africa, three different tropical cyclones churned in the Pacific Ocean, and large clouds of dust blew over deserts in Africa and Asia.
By 2050, an estimated 83.7 million people over the age of 65 will call the US home, nearly doubling the current population—and a paper published in April found that bad smoke days during California’s 2015 wildfire season caused spikes in emergency room visits, with the most pronounced impact on patients over 65.
In a recently published study, US Forest Service researchers Sonya Sachdeva and Sarah McCaffrey found that, when analyzed in large numbers, tweets about wildfires can accurately model the way smoke moves.In their study, published by the International Conference on Social Media & Society, Sachdeva and McCaffrey analyzed close to 39,000 tweets posted between May and September 2015 in California.
