Novel method of generation of Ca(HCO3)2 and CaCO3 aerosols and first determination of hygroscopic and cloud condensation nuclei activation properties
Ca(HCO3)2 and CaCO3 aerosols hygroscopic and cloud condensation nuclei activation properties
2010/9/21
Atmospheric mineral aerosols contain CaCO3 as a reactive component. A novel method to produce CaCO3 aerosol was developed by spraying Ca(HCO3)2 solution, which was generated from a CaCO3 suspension an...
Determination of particulate lead using aerosol mass spectrometry: MILAGRO/MCMA-2006 observations
particulate lead aerosol mass spectrometry MILAGRO/MCMA-2006 observations
2010/8/13
We report the first measurements of particulate lead (Pb) from Aerodyne Aerosol Mass Spectrometers, which were deployed in and around Mexico City during the Megacity Initiative: Local and Global Resea...
Ice nucleation properties of mineral dust particles: determination of onset RHi, IN active fraction, nucleation time-lag, and the effect of active sites on contact angles
mineral dust particles onset RHi IN active fraction nucleation time-lag

A newly developed ice nucleation experimental set up was used to investigate the heterogeneous ice nucleation properties of three Saharan and one Spanish dust particle samples. It was observed that th...
Technical Note: Determination of aerosol optical properties by a calibrated sky imager
Technical Note aerosol optical properties calibrated sky imager
2009/9/11
The calibrated ground-based sky imager developed in the Marine Physical Laboratory, the Whole Sky Imager (WSI), has been tested with data from the Atmospheric Radiation Measurement Program (ARM) at th...
The oxidation efficiency of the troposphere is largely determined by the hydroxyl radical and its global distribution. Its presence limits the lifetime of most trace gases. Because of the great import...
A novel method for estimating the mixing height based on ceilometer measurements is described and tested against commonly used methods for determining mixing height. In this method an idealised backsc...
