Welcome to the First International SPARTAN Meeting Thank You! Yinon Rudich, Michael Brauer, Aaron Cohen, Vanderlei Martins & AirPhoton, Yang Liu, Mark Gibson, Yvonne Ritchie & Prior Coop Students, Crystal Weagle, Graydon Snider Health and Environments Research Centre (HERC), Gibson Lab, Gangon Lab The SPARTAN community: 25 institutions, 12 countries NSERC Dalhousie University 9 Jun 2015

van Donkelaar et al., EHP, 2015 How Reliable are Satellite-Derived PM 2.5 Concentrations? Global Burden of Disease Assessments (IHME, WHO) Yale-Columbia Environmental Performance Index OECD Regional Well Being Index World Bank World Development Indicators Range of Epidemiologic studies (low PM 2.5, asthma, diabetes) Contributed to Canadian annual PM 2.5 standard (Crouse et al., 2012) Satellite-derived PM 2.5 used in:

Long-Term “Dry” PM 2.5 to AOD Relation Affected by vertical structure, aerosol properties, relative humidity Model sampled coincidently with MODIS and MISR observations GEOS-Chem Simulation of PM 2.5 / AOD for van Donkelaar et al., EHP, 2010 PM 2.5 / AOD (μg m -3 ) PM 2.5 calculated at 35% RH

Few (no??) Operational Collocated Measurements of PM 2.5 & AOD Sites with AOD and PM 2.5 measurements within 3 km

Current Status of SPARTAN Measures PM 2.5 Mass & Composition at Populated Sites Measuring AOD Semi-Autonomous PM 2.5 & PM 10 Impaction Sampling Station (AirPhoton) Ions & metals 3-λ Nephelometer AOD from CIMEL Sunphotometer (e.g. AERONET) Snider et al., AMT, 2015 Testing Deployed Committed Also Only Global Consistent PM 2.5 Network

Seek Your Ideas to Extract More Information from SPARTAN Information Accuracy? Information Quantities? Agenda Tuesday AM: Overview Tuesday PM: SPARTAN Operating Procedures & Lab Tours Wednesday AM: SPARTAN Analyses Wednesday PM: Looking Forward

Slides for Wednesday

Planned Activities Dalhousie –PM 2.5 Composition (Graydon Snider & Crystal Weagle) –Evaluate GEOS-Chem PM 2.5 / AOD (Crystal Weagle & Graydon Snider) –Analyzing intercomparisons (Mammoth Cave, Harvard Impactor, …) –Logistics of upgrading instruments (inlets, clean air reference) –Logistics with sustaining sites and future growth Others?

Planned Instrument Upgrades for All Sites Sampling Station Baffles (for remaining sites without them) PM 2.5 cyclone inlet (4 or 5 lpm) for sampling station Nephelometer Teflon mesh inlet Clean air reference system PM 10 size cut Protocol changes For each cartridge, 1 PM 10 filter / cartridge (reduces operating costs while maintaining network objectives) Periodic (monthly?) nephelometer calibration with CO 2 and clean air Send filter extracts to Kroll group at MIT for organic analysis? Store (-20 C) one filter/site/yr for archive???

Discussion of Priority Deployments Proposed Locations for Next Loans Bujumbara, Burundi Lahore, Pakistan Mexico City Are there other locations that could purchase instrumentation? Other Considerations China has emerging PM 2.5 mass & speciation networks India has an emerging PM 2.5 mass network Testing Deployed Committed Proposed Low PM 2.5 MAIA Validation

Future WMO aerosol Scientific Advisory Group: SPARTAN appropriate for its objectives. To become WMO GAW Contributing Network involves –Nephelometer PM 10 size cut (now planned) –Airphoton nephelometer participates in GAW instrument intercomparison (how coordinate?) –Dry vs ambient scatter Benefits from endorsement by other organizations (e.g. IGAC) Next Meeting? In a year? Who to invite? How fund? Funding opportunities
