Since 2021, CIRES researchers have helped lead a new air quality monitoring program, which includes 12 sites across the U.S. They set up a suite of instruments that collect high-resolution air samples day and night. Read more: https://t.co/nAHNWeitYR

Our big smoke volatility paper is out! We flew a thermal denuder and showed good agreement with lab VBS. This closes much of the gap in the OA/CO differences between airborne and ground studies

CIRES' Guy Symonds, Doug Day, and Pedro Campuzano recently traveled overseas to support the NASA-led Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) mission. @JgrpBoulder @CUBoulder

For the past 2 months, we have been participating in the ASIA-AQ @NASAAirborne mission https://t.co/TSSP0kEVvE
to study AQ in Asia (Philippines, Korea, Taiwan, Thailand) with a focus on urban and biomass burning pollution.

A new preprint from our group ona method for calibrating AMS and EESI for complex mixtures (e.g. chamber secondary aerosol) by first separating the compounds with HPLC

Work led by @MindySchueneman, with @DougChem @Pedro_CUBoulder @SeonsikY @DKim_Chem @jljcolorado et al

[Jimenez Group CU-Boulder @JgrpBoulder]

Come learn about our work on sources of SOA vs volatility classes in LA using a novel tubing+OFR technique!

Melissa Morris presents this work at #aaar2023, @AmericanAerosol Annual Meet tomorrow at 10:30am in Portland. Session "Aerosol Chem X: Gas-phase SOA Precursors" (ballroom)

[Jimenez Group CU-Boulder @JgrpBoulder]

Come learn about our work on quantification of anthropogenic and pyrogenic particulate bromine by AMS!

@DKim_Chem presents this work at #aaar2023, @AmericanAerosol Annual Meeting tomorrow 9:45am in Portland. Session: "12RA Remote and Regional Atmospheric Aerosols III" (Rm F150)

[Jimenez Group CU-Boulder @JgrpBoulder]

@jljcolorado presents work on the health impacts of GUV222-generated pollution under low ventilation, showing that it may be its most important limitation at #aaar2023, @AmericanAerosol Annual Meeting in Portland, OR.

@amgcarlton @AmericanAerosol Congrats!
(and nice seeing you today)

[Doug Day @DougChem]

Looking forward to sharing a few highlights on this work today at 10am at #AAAR2023

Work together with @jljcolorado @Pedro_CUBoulder @Benjamin_AtmChm and Donna Sueper (@ciresnews @cuboulder)

[Jimenez Group CU-Boulder @JgrpBoulder]

Come learn about our work on methods and software to quantify organic nitrates using AMS!

@DougChem will present this work at #aaar2023, @AmericanAerosol Annual Meeting tomorrow @ 10:00am in Portland in session: "1IM Instrumentation & Methods I: Chemical Instrumentation" Rm F150

1/ We just installed an (outdoor) volatile organic compound (VOC) real time instrument at the Denver site of @NSF @ASCENT_USA measurement network

We are very grateful to @tofwerk, who's lending it to us for a month & to @CDPHE who is our host

Here w/ the ASCENT instruments

@GouwLab @ARJensenChem Congrats @ARJensenChem, nice talk, good luck, and a pleasure working with you!

Virtual Special Issue “Advances in Atmospheric Chemical and Physical Processes” Edited by J. Burkholder + J. Orlando out in @JPhysChem A.

Many insightful papers on chem kinetics, rxn mechs, hetero/interface proc, aqueous chem, aerosol proc, theoretical.

1/ Happy to share that our paper on yields & composition for monoterpenes + NO3 radical and RO2 fate is published.

TLDR for general public: trees emit monoterpenes (a reason forests smell good). Those react with oxidants and make particle pollution (haze)
