CASE STUDY #1: How can I use satellite-based indicators for ozone sensitivity to NOx vs. VOC emissions in a SIP?

HAQAST member Arlene Fiore & Xiaomeng Jin (LDEO/Columbia) provided

HCHO/NO2 trends and maps used by CT DEEP in their SIPs.

CASE STUDY #3: How can I incorporate satellite data into boundary conditions used by my regional model?

HAQAST member Jessica Neu (NASA JPL) is generating boundary conditions for use by SCAQMD in their SIP modeling. BAAQMD also interested.

Emerging Question: What are the spatiotemporal trends of NH3 in Cache Valley, Utah?

AMoNLogansite(UT01)

NH3 maximized in northern portion of Valley

SpaHalmapofIASINH3for2008-2016: IASIsatelliteNH3within±30kmco-averagedoversameHmeasAMoNsite:

• Weak correlation likely due to high spatiotemporal variability, extreme values (among poorest correlation of all AMoN sites)

• Cache Valley among the worst PM2.5 in nation due to large agricultural activities • Highest annual NH3 in AMoN network but limited spatiotemporal information
