Black carbon over Mexico: the effect of atmospheric transport on mixing state, mass absorption cross-section, and BC/CO ratios
Black carbon Mexico atmospheric transport BC/CO ratios
2010/1/18
A single particle soot photometer (SP2) was operated on the NCAR C-130 during the MIRAGE campaign (part of MILAGRO), sampling black carbon (BC) over Mexico. The highest BC concentrations were measured...
Absolute absorption cross-section and photolysis rate of I2
Absolute absorption cross-section photolysis rate I2
2009/3/4
Following recent observations of molecular iodine (I2) in the coastal marine boundary layer (MBL) (Saiz-Lopez and Plane, 2004), it has become important to determine the absolute absorption cross-secti...
Effects of column density on I2 spectroscopy and a determination of I2 absorption cross section at 500 nm
column density I2 spectroscopy I2 absorption cross section
2009/1/9
The use of ro-vibronic spectra of I2 in the region of 543 nm to 578 nm as reference spectra for atmospheric Differential Optical Absorption Spectroscopy is studied. It is shown that the retrieval of a...
Estimation of the mass absorption cross section of the organic carbon component of aerosols in the Mexico City Metropolitan Area

Data taken from the MCMA-2003 and the 2006 MILAGRO field campaigns are used to examine the absorption of solar radiation by the organic component of aerosols. Using irradiance data from a Multi-Filter...
Investigation of the formaldehyde differential absorption cross section at high and low spectral resolution in the simulation chamber SAPHIR
formaldehyde spectral resolution SAPHIR
2008/11/12
The results from a simulation chamber study on the formaldehyde (HCHO) absorption cross section in the UV spectral region are presented. We performed 4 experiments at ambient HCHO concentrations with ...
