New study questions the idea that the solution to pollution is dilution

A recent article by EOS writer Jackie Rocheleau highlights a growing concern about wildfire smoke and other pollutants that continue to exist in a diluted quantity within our atmosphere. With wildfires growing in size and quantity due to climate change, the original idea that simply waiting for the pollutants to disperse would be enough to protect human health, is coming into question. 

Postdoctoral scholar position

Postdoctoral scholar position:  Hygroscopicity and CCN potential of organic functional groups in ambient aerosol, University of California, Davis

The Air Quality Research Center (AQRC) at the University of California, Davis is seeking a postdoctoral scholar to perform laboratory research to investigate the hygroscopicity and CCN potential of organic functional groups in aerosol. The post-doctoral fellow will be mentored by Drs. Ann M. Dillner and Anthony Wexler.

Nationwide Speciated Particulate Monitoring – IMPROVE and CSN at UC Davis

Overview

The Air Quality Monitoring Team (AQMT) at UC Davis has operated the Interagency Monitoring of Protected Visual Environments (IMPROVE) ambient speciated particulate monitoring network since its inception in 1988. Beginning in 2015, AQMT took on the laboratory analysis and data handling for the Chemical Speciation Network (CSN). These two networks encompass over 300 sites delivering over 60 PM2.5 species across the country every third day.

Do Not Steal.

Introduction

In the narrative of the “Tragedy of the Commons”,(1,2) a shared grazing area (aka common pool resource(3)) is trampled into overgrazed ruin by a pervasion of actors who exploit the resource more quickly than can be sustainably allotted. Regardless of whether there is consciousness of guilt, this is theft.

Earth Day Experts

Earth Day is this Thursday, April 22 and to help reporters develop stories about air quality monitoring, modeling and evaluation, the Air Quality Research Center is here with a few researchers and educators to support the sharing of knowledge.

How much of a problem is the CO2 emitted by CA Wildfires?

Over 111 million metric tons of CO2 were emitted by wildfires in California for the 2020 year. The transportation sector is the only area to have emitted more carbon dioxide at over 169 million metric tons. While from the outset, that looks pretty bad, you may still wonder, "In actuality, how bad is the wildfire smoke for Climate Change?"

In an interview with the SF Chronical, AQRC Director, Tony Wexler, stated that the wildfire carbon emissions are of almost no concern for him in relation to climate change.

Inexpensive Air Quality Sensors here for our Climate Catastrophe

As our atmosphere rapidly accepts pollutants and the planet rises in temperature, small air quality sensors are becoming more affordable and widely used.

Low-cost air quality sensors are becoming more accurate and affordable to the general public month by month. There is a grand amount of research occurring in the field so air quality sensors. Government, private industry, non-profits and community scientists are all concerned about the air pollution around the world.
