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
