Thermodynamic characterization of Mexico City aerosol during MILAGRO 2006

We used di ff erent inlet configurations to measure the particulate phase of the aerosol, the instrumental background and the gas-phase component of the aerosol. The PTR-

The latter were obtained using an online aerosol thermodynamic equilibrium model (AIM) (Wexler and Clegg, 2002) with the measured non-refractory ammonium, sulfate, nitrate, and

The AMS-PMF time series results are compared with molecular level detail of the CIMS gas-phase and MOVI-HRToF-CIMS aerosol- phase measurements, linking the HR-ToF-AMS high

In the rural site T2 both the measured and predicted av- erage OA concentrations are approximately 10–20 % lower than the corresponding values at T1 (Fig. Given the dilu- tion

The final data set of the aerosol optical and microphysical properties along with the water vapor profiles were incorporated into the ISORROPIA II model (Fountoukis and Nenes, 2007)

(2009) coupled fast measurements of aerosol and gas-phase constituents with the ISORROPIA-II thermodynamic model to study the partitioning of semivolatile inorganic species and

As part of the Megacity Initiative: Local and Global Re- search Observations (MILAGRO) 2006 field campaign, we measured the fluxes (positive emission fluxes and nega- tive
