Fluxes of reactive organic gases seasonal intercomparison of chemical lifetimes and emissions

Sub–micron particulate matter (PM1) in the New York (NY) metropolitan area impacts air quality and human health. We characterized refractory black carbon (BC) and non–refractory (NR) PM1 in Mineola, NY during winter 2024 and NR-PM1 during summer 2023. This study investigated seasonal differences in PM1, drivers of wintertime PM1 elevated events, and potential health effects on local communities. Organic aerosol (OA) dominates both winter (63 %) and summer (86 %) NR–PM1. Primary OA dominates winter PM1 (57 %) with cooking organic aerosol (COA) contributing on average 29 %, but up to 81 % of elevated PM1 events. In summer, OA was impacted by wildfire smoke and biogenic sources; COA averaged only 9 % of OA, but sporadically enhanced OA and drove several PM1 events. BC accounted for 6 % of winter PM1. BC coating thickness increased during wintertime events relative to the campaign average, although modeled respiratory deposition showed that accompanying size changes did not shift respirator..., , # Fluxes of reactive organic gases seasonal intercomparison of chemical lifetimes and emissions

## Description of the data and file structure

Particluate Matter data from the Fluxes of Reactive Organic Gases Seasonal Intercomparison of Chemical Lifetimes and Emissions (FROGSICLE). Data is from a Scanning Mobility Particle Sizer (SMPS), Aerosol Chemical Speciation Monitor (ACSM), and Single Particle Soot Photometer (SP2). All data is in the [ICARTT](https://www-air.larc.nasa.gov/missions/etc/IcarttDataFormat.htm) format.
