Simultaneous HONO measurements in and above a forest canopy: influence of turbulent exchange on mixing ratio differences
HONO measurements a forest canopy turbulent exchange ratio differences
2011/2/24
We have combined chemical and micrometeorological measurements to investigate the formation and distribution of HONO throughout a forest canopy. HONO was measured simultaneously at two heights, close ...
Simulation of low clouds in the Southeast Pacific by the NCEP GFS: sensitivity to vertical mixing
low clouds the Southeast Pacific the NCEP GFS vertical mixing
2010/12/28
The NCEP Global Forecast System (GFS) model has an important systematic error shared by many other models: stratocumuli are missed over the subtropical eastern oceans. It is shown that this error can ...
Analysis of 13C and 18O isotope data of CO2 in CARIBIC aircraft samples as tracers of upper troposphere/lower stratosphere mixing and the global carbon cycle
13C and 18O isotope data CO2 CARIBIC aircraft samples the global carbon cycle
2010/9/21
The project CARIBIC (http://caribic-atmospheric.com) aims to study atmospheric chemistry and transport by regularly measuring many compounds in the free troposphere and the upper troposphere/lowermost...
CO2 column-averaged volume mixing ratio derived over Tsukuba from measurements by commercial airlines
CO2 column-averaged volume mixing ratio Tsukuba commercial airlines
2010/8/25
Column-averaged volume mixing ratios of carbon dioxide (XCO2) during the period from January 2007 to May 2008 over Tsukuba, Japan, were derived using CO2 concentrations measured by Continuous CO2 Meas...

2010/8/16
Aerosol microphysics, chemical composition, and CCN concentrations were measured at the T0 urban supersite in Mexico City during Megacity Initiative: Local and Global Research Observations (MILAGRO) i...
Lagrangian mixing in an axisymmetric hurricane model
Lagrangian mixing an axisymmetric hurricane model
2010/8/16
This paper discusses the extension of established Lagrangian mixing measures to make them applicable to data extracted from a 2-D axisymmetric hurricane simulation. Because of the non-steady and unbou...
CCN predictions using simplified assumptions of organic aerosol composition and mixing state: a synthesis from six different locations
CCN predictions organic aerosol composition a synthesis six different locations
2010/8/13
An accurate but simple quantification of the fraction of aerosol particles that can act as cloud condensation nuclei (CCN) is needed for implementation in large-scale models. Data on aerosol size dist...
A detailed aerosol mixing state model for investigating interactions between mixing state, semivolatile partitioning, and coagulation

A new method for describing externally mixed particles, the Detailed Aerosol Mixing State (DAMS) representation, is presented in this study. This novel method classifies aerosols by both composition a...
Vertically-resolved particle size distribution within and above the mixing layer over the Milan metropolitan area
Vertically-resolved particle size distribution the mixing layer
2010/8/12
Vertical aerosol profiles were directly measured over the city of Milan during three years (2005–2008) of field campaigns. An optical particle counter, a portable meteorological station and a miniatur...
Advective mixing in a nondivergent barotropic hurricane model
nondivergent barotropic hurricane model Advective mixing
2010/2/1
This paper studies Lagrangian mixing in a two-dimensional barotropic model for hurricane-like vortices. Since such flows show high shearing in the radial direction, particle separation across shear-li...
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...
High Arctic lakes as sentinel ecosystems: Cascading regime shifts in climate, ice cover, and mixing
