Thermodynamic characterization of Mexico City aerosol during MILAGRO 2006
Fast measurements of aerosol and gas-phase constituents coupled with the ISORROPIA-II thermodynamic equilibrium model are used to study the partitioning of semivolatile inorganic species and phase state of Mexico City aerosol sampled at the T1 site during the MILAGRO 2006 campaign. Overall, predicted semivolatile partitioning agrees well with measurements. PM2.5 is insensitive to changes in amm...

متن کاملSource apportionment of fine organic aerosol in Mexico City during the MILAGRO experiment 2006
Organic carbon (OC) comprises a large fraction of fine particulate matter (PM2.5) in Mexico City. Daily and select 12-h PM2.5 samples were collected in urban and peripheral sites in Mexico City from 17–30 March 2006. Samples were analyzed for OC and elemental carbon (EC) using thermal-optical filter-based methods. Real-time watersoluble organic carbon (WSOC) was collected at the peripheral site...
متن کاملAerosol effects on the photochemistry in Mexico City during MCMA-2006/MILAGRO campaign
In the present study, the impact of aerosols on the photochemistry in Mexico City is evaluated using the WRFCHEM model for the period from 24 to 29 March during the MCMA-2006/MILAGRO campaign. An aerosol radiative module has been developed with detailed consideration of aerosol size, composition, and mixing. The module has been coupled into the WRF-CHEM model to calculate the aerosol optical pr...
متن کاملChemically - resolved aerosol eddy covariance flux measurements in urban Mexico City during MILAGRO 2006
As part of the MILAGRO 2006 field campaign, the exchange of atmospheric aerosols with the urban landscape was measured from a tall tower erected in a heavily populated neighborhood of Mexico City. Urban submicron aerosol fluxes were measured using an eddy covariance method with a quadrupole aerosol mass spectrometer during a two week period in March, 2006. Nitrate and ammonium aerosol concentra...
