Evaluation of dust trace metal estimates
2014/12/12
The Community Multiscale Air Quality (CMAQ)
model is a state-of-the-science air quality model that simulates the emission, transformation, transport, and fate of the
many different air pollutant spe...
Multi-annual changes of NOx emissions in megacity regions: nonlinear trend analysis of satellite measurement based estimates
NOx emissions megacity regions nonlinear trend analysis satellite measurement
2010/9/8
Hazardous impact of air pollutant emissions from megacities on atmospheric composition on regional and global scales is currently an important issue in atmospheric research. However, the quantificatio...
Empirical estimates of CCN from aerosol optical properties at four remote sites
Empirical estimates CCN aerosol optical properties four remote sites
2010/7/23
This study presents an empirical method to estimate the CCN concentration as a function of percent supersaturation. The aerosol optical properties, backscatter fraction and single scatter albedo, func...
Quantitative estimates of the volatility of ambient organic aerosol
ambient organic aerosol a tandem thermodenuder-aerosol mass spectrometer system Mexico City
2010/6/21
Measurements of the sensitivity of organic aerosol (OA, and its components) mass to changes in temperature were recently reported by Huffman et al.~(2009) using a tandem thermodenuder-aerosol mass spe...
Estimates of biomass burning emissions in tropical Asia based on satellite-derived data
Estimates biomass burning emissions tropical Asia satellite-derived data
2010/3/8
Biomass burning in tropical Asia emits large amounts of trace gases and particulate matter into the atmosphere, which has significant implications for atmospheric chemistry and climatic change. In thi...
Global estimates of CO sources with high resolution by adjoint inversion of multiple satellite datasets（MOPITT, AIRS, SCIAMACHY, TES）
CO sources MOPITT AIRS SCIAMACHY TES
2010/2/1
We combine CO column measurements from the MOPITT, AIRS, SCIAMACHY, and TES satellite instruments in a full-year (May 2004–April 2005) global inversion of CO sources at 4°×5° spatial resolution and mo...
We report here top-down emissions estimates for an African megacity. A boundary layer circumnavigation of Lagos, Nigeria was completed using the FAAM BAe146 aircraft as part of the AMMA project. These...
Characterisation of long-term climate change by dimension estimates of multivariate palaeoclimatic proxy data
long-term climate change dimension estimates multivariate palaeoclimatic proxy data
2009/11/9
The problem of extracting climatically relevant information from multivariate geological records is tackled by characterising the eigenvalues of the temporarily varying correlation matrix. From these ...
Comparison of conventional Lagrangian stochastic footprint models against LES driven footprint estimates
conventional Lagrangian stochastic footprint models LES footprint estimates
2009/8/7
In this study we introduce a comparison method for footprint model results by evaluating the performance of conventional Lagrangian stochastic (LS) footprint models that use parameterised flow field c...
Accurate satellite-derived estimates of the tropospheric ozone impact on the global radiation budget
Accurate satellite-derived estimates tropospheric ozone global radiation budget
2009/7/15
Estimates of the radiative forcing due to anthropogenically-produced tropospheric O3 are derived primarily from models. Here, we use tropospheric ozone and cloud data from several instruments in the A...
Flux estimates of isoprene, methanol and acetone from airborne PTR-MS measurements over the tropical rainforest during the GABRIEL 2005 campaign
Flux estimates isoprene methanol airborne PTR-MS tropical rainforest
2009/7/15
Tropical forests are a strong source of biogenic volatile organic compounds (BVOCs) to the atmosphere which can potentially impact the atmospheric oxidation capacity. Here we present airborne and grou...
Climate change odds much worse than thought-New analysis shows warming could be double previous estimates
climate change warming previous estimates global change
2009/5/20
The study uses the MIT Integrated Global Systems Model, a detailed computer simulation of global economic activity and climate processes that has been developed and refined by the Joint Program on the...
SCIAMACHY formaldehyde observations: constraint for isoprene emission estimates over Europe?
SCIAMACHY formaldehyde isoprene emission Europe
2009/3/13
Formaldehyde (HCHO) is an important intermediate compound in the degradation of volatile organic compounds (VOCs) in the troposphere. Sources of HCHO are largely dominated by its secondary production ...
