Weather and Air Quality Fred Moshary- Optical Remote Sensing Lab Summer Season also brings with itself severe weather and air quality problems Hot weather leads to severe storm, wild fires and heatwaves At the same time, to deal with the heat, we consume more energy cooling our living spaces and cars leading to increased emissions. Hot and sunny weather is also ideal conditions for atmospheric chemistry that leads to both particulate and ozone air quality issues During heat waves, man-made emissions of oxides of nitrogen and organic compounds interact in the presence of sunlight to produce tropospheric ozone The precursors to ozone can travel for miles before reacting to produce ozone, so a broader region is impacted Dry season leads to forest fires to the west that result in smoke that travels across US to impact our region Particulate formation and growth in humid conditions is notable during summer

Summer Air Quality Campaign in NYC region We are engaged in a multi-institutional air quality research campaign this summer involving NOAA, NASA, EPA, States of NJ, NY, and CT, as well as Univ of MD, SUNY Albany and Stony Brook to name a few The study is termed LISTOS: Long Island Sound Tropospheric Ozone Study The study looks at impact of New York City on coastal Long Island and Connecticut along the shores of Long Island Sound
