The potential to narrow uncertainty in projections of stratospheric ozone over the 21st century
stratospheric ozone the 21st century
2010/10/11
Future stratospheric ozone concentrations will be determined both by changes in the concentration of ozone depleting substances (ODSs) and by changes in stratospheric and tropospheric climate, includi...
Uncertainty assessment of current size-resolved parameterizations for below-cloud particle scavenging by rain
current size-resolved parameterizations below-cloud particle rain
2010/8/13
Current theoretical and empirical size-resolved parameterizations of the scavenging coefficient (Λ), a parameter commonly used in aerosol transport models to describe below-cloud particle scavenging b...
Multi-parameter uncertainty analysis of a bifurcation point
Multi-parameter uncertainty analysis bifurcation point
2009/11/9
Parameter uncertainty analysis of climate models has become a standard approach for model validation and testing their sensitivity. Here we present a novel approach that allows one to estimate the rob...
Uncertainty in global CCN concentrations from uncertain aerosol nucleation and primary emission rates
global CCN concentrations uncertain aerosol nucleation emission rates
2009/3/13
The indirect effect of aerosols on climate is highly uncertain and limits our ability to assess anthropogenic climate change. The foundation of this uncertainty is uncertainty in the number of cloud c...
Quantification of the impact of climate uncertainty on regional air quality
Quantification climate uncertainty regional air quality
2009/3/13
Uncertainties in calculated impacts of climate forecasts on future regional air quality are investigated using downscaled MM5 meteorological fields from the NASA GISS and MIT IGSM global models and th...
Assessing positive matrix factorization model fit: a new method to estimate uncertainty and bias in factor contributions at the measurement time scale
Assessing positive matrix factorization model factor contributions measurement time scale
2009/3/12
A Positive Matrix Factorization receptor model for aerosol pollution source apportionment was fit to a synthetic dataset simulating one year of daily measurements of ambient PM2.5 concentrations, comp...
The effects of experimental uncertainty in parameterizing air-sea gas exchange using tracer experiment data
parameterizing air-sea gas tracer
2009/3/12
It is not practical to measure air-sea gas fluxes in the open ocean for all conditions and areas of interest. Therefore, in many cases fluxes are estimated from measurements of air-phase and water-pha...
Parametric sensitivity and uncertainty analysis of dimethylsulfide oxidation in the clear-sky remote marine boundary layer
Parametric sensitivity dimethylsulfide oxidation clear-sky remote marine boundary layer
2009/2/11
Local and global sensitivity and uncertainty methods are applied to a box model of the dimethylsulfide (DMS) oxidation cycle in the remote marine boundary layer in order to determine the key physical...
Search for evidence of trend slow-down in the long-term TOMS/SBUV total ozone data record: the importance of instrument drift uncertainty
long-term TOMS/SBUV total ozone instrument drift uncertainty
2009/1/15
We have developed a merged ozone data set (MOD) for the period October 1978 through June 2006 combining total ozone measurements (Version 8 retrieval) from the TOMS (Nimbus 7, Earth Probe) and SBUV/SB...
Uncertainty analysis for estimates of the first indirect aerosol effect
Uncertainty analysis first indirect aerosol effect
2009/1/14
The IPCC has stressed the importance of producing unbiased estimates of the uncertainty in indirect aerosol forcing, in order to give policy makers as well as research managers an understanding of the...
