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 University9 Jun 2015
van Donkelaar et al., EHP, 2015
How Reliable are Satellite-Derived PM2.5 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 PM2.5, asthma, diabetes)
Contributed to Canadian annual PM2.5 standard (Crouse et al., 2012)
Satellite-derived PM2.5 used in:
Long-Term “Dry” PM2.5 to AOD Relation
Affected by vertical structure, aerosol properties, relative humidityModel sampled coincidently with MODIS and MISR observations
GEOS-Chem Simulation of PM2.5 / AOD for 2001-2006
van Donkelaar et al., EHP, 2010
PM2.5 / AOD (μg m-3)
PM2.5 calculated at 35% RH
Few (no??) Operational Collocated Measurements of PM2.5 & AOD
Sites with AOD and PM2.5 measurements within 3 km
Current Status of SPARTANMeasures PM2.5 Mass & Composition at Populated Sites
Measuring AOD
Semi-Autonomous PM2.5 & PM10 Impaction Sampling Station (AirPhoton)Ions & metals
3-λ Nephelometer
AOD from CIMEL Sunphotometer (e.g. AERONET)

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– PM2.5 Composition (Graydon Snider & Crystal Weagle)
– Evaluate GEOS-Chem PM2.5 / 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)• PM2.5 cyclone inlet (4 or 5 lpm) for sampling station
Nephelometer• Teflon mesh inlet• Clean air reference system• PM10 size cut
Protocol changes• For each cartridge, 1 PM10 filter / cartridge (reduces operating costs
while maintaining network objectives)• Periodic (monthly?) nephelometer calibration with CO2 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 LoansBujumbara, BurundiLahore, PakistanMexico City
Are there other locations that could purchase instrumentation?
Other Considerations• China has emerging PM2.5 mass & speciation networks• India has an emerging PM2.5 mass network
Testing Deployed Committed
Proposed Low PM2.5
MAIA Validation
Future
• WMO aerosol Scientific Advisory Group: SPARTAN appropriate for its objectives. To become WMO GAW Contributing Network involves– Nephelometer PM10 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
