Agricultural burning monitored for air pollutants in Imperial County; exposure reduction recommendations developed

California Agriculture, 2012
Air pollutants, notably particulate matter (PM) with aerodynamic diameter smaller than 2.5 micrometers (PM2.5), are emitted during agricultural burning. We studied a winter period in Imperial County when predominantly bermuda-grass stubble was burned. At

Development of multi-scale indices of human mobility restriction during the COVID-19 based on air quality from local and global NO2 concentration

iScience, 2023
Summary: This study investigated whether variability in air quality, especially related to vehicular emissions, during the COVID-19 pandemic could indicate social distancing. Data from in situ measurements and satellite estimates were used.

Fumigant emission reductions with TIF warrant regulatory changes

California Agriculture, 2013
With methyl bromide's phase-out, most growers have turned to alternative fumigants, particularly 1,3-dichloropropene (1,3-D) and chloropicrin. These alternatives are tightly regulated because they are classified as toxic air contaminants and volatile ...

Atmospheric blockages as trigger of environmental contingencies in Mexico City

Heliyon, 2019
Atmospheric pollution in cities is due to several human factors, for instance the number of cars in circulation, fuel efficiency and industrial waste, as well as orographic and meteorological conditions that determine air circulation. Ozone contingencies

Positive feedback to regional climate enhances African wildfires

iScience, 2023
Summary: Regional climate strongly regulates the occurrence of wildfires partly because drying of fuel load increases fires. The large amounts of aerosols released by wildfires can also strongly affect regional climate.

Climate warming and summer monsoon breaks drive compound dry and hot extremes in India

iScience, 2022
Summary: Considering the severe impacts of compound dry and hot extremes, we examine the primary drivers of CDHEs during the summer monsoon in India. Using ERA5 reanalysis, we show that most of the CDHEs in India occur during the droughts caused by the ...
