#smoke

10 posts10 participants0 posts today

With #wildfires raging across large areas of Western Canada (none really close to me, but a few not that far in the bigger picture- couple hours drive or less?) it was inevitable that the smoke would reach us sooner or later depending on wind patterns. Late last week we started to get a bit of haze peaking a couple of days over the #weekend with strong visible #smoke and smell.

Fluorescent light reveals invisible #smoke at high altitudes - as currently from Canadian #wildfires across Europe
#ForestFires could have a greater impact on clouds and #climate than previously assumed

EurekAlert!Fluorescent light reveals invisible smoke at high altitudes - as currently from Canadian wildfires across EuropeThe fluorescence lidar technology does not only enable a better determination of the origin of particles in the atmosphere. The method can also visualise particle layers that were previously practically invisible. This is the conclusion drawn by a team from the Leibniz Institute for Tropospheric Research (TROPOS) from the evaluation of 250 hours of lidar measurements over Leipzig in 2022 and 2023. The researchers had repeatedly observed very thin layers of smoke at high altitudes, which originated from forest fires in Canada but could not be seen using conventional methods. This suggests that the upper troposphere over Europe may be more polluted than previously assumed, especially during the summer forest fire season, the research team writes in the journal Atmospheric Chemistry and Physics. The observations suggest that thin layers of smoke can favour the formation of ice clouds. The fluorescence method offers great opportunities for a more detailed investigation of such interactions between aerosols and clouds. The measurements in Leipzig are once again showing wildfire smoke from Canada. This smoke is therefore not only visible on satellite images, but can now be analysed in more detail using fluorescence lidar technology.

If you're in an area getting smoke from the Canadian wildfires, here's an additional reason to take precautions, like masking up:

"There’s much more to wildfire smoke than charred sticks and leaves, especially where these blazes are burning in Canada. The country’s forests have long been mined, operations that loaded soils and waterways with toxic metals like lead and mercury, especially before clean-air standards kicked in 50 years ago.

"Now everyone downwind of these wildfires may have to contend with that legacy and those pollutants, in addition to all the other nasties inherent in wildfire smoke."

"What exactly is lurking in the smoke from Canadian wildfires will require further testing by scientists."

As northern states were dealing w/ #smoke, a large plume of #Saharan #dust is expected to spread over #GulfCoast states through Thurs. Chenard said the dust had reached parts of #Florida by Wed morning, & was expected to intensify.

“The highest concentrations of the dust is definitely going to be through today & tonight,” he said. “But there will be some at least lower concentrations that linger over Florida, probably into the weekend.”

Marc Chenard, a meteorologist at the Weather Prediction Center, said satellite imagery shows a broad swath of #smoke still covering the eastern US on Wednesday. The smoke stretches from northern #Georgia to #NewEngland & into the Upper #Midwest.

#AirQuality readings in cities including #Minneapolis, #StPaul & #Columbus, #Ohio, were at “very unhealthy” levels… acc/to the NYT air quality tracker.

Dr. Rachel Strykowski, a #pulmonologist, said the poor #AirQuality increases #respiratory symptoms aggravated by the dirty #air. Typical symptoms include increase in shortness of breath, wheezing, coughing, & flares of underlying #disease such as #COPD & #asthma.

The fine particulate matter from the #wildfire #smoke triggers more inflammation in patients’ airways, aggravating underlying #medical conditions.
