Estimating European volatile organic compound emissions using satellite observations of formaldehyde from the Ozone Monitoring Instrument
European volatile organic compound satellite observations the Ozone Monitoring Instrument
2010/12/20
Emission of non-methane Volatile Organic Compounds (VOCs) to the atmosphere stems from biogenic and human activities, and their estimation is difficult because of the many and not fully understood pro...
Estimating the maritime component of aerosol optical depth and its dependency on surface wind speed using satellite data
the maritime component aerosol optical depth surface wind speed satellite data
2010/8/16
Six years (2003–2008) of satellite measurements of aerosol parameters from the Moderate Resolution Imaging Spectroradiometer (MODIS) and surface wind speeds from Quick Scatterometer (QuikSCAT), the Ad...
Estimating surface CO2 fluxes from space-borne CO2 dry air mole fraction observations using an ensemble Kalman Filter
surface CO2 fluxes space-borne CO2 ensemble Kalman Filter
2009/5/6
We have developed an ensemble Kalman Filter (EnKF) to estimate 8-day regional surface fluxes of CO2 from space-borne CO2 dry-air mole fraction observations (XCO2) and evaluate the approach using a ser...
Application of the variability-size relationship to atmospheric aerosol studies: estimating aerosol lifetimes and ages
variability-size relationship atmospheric aerosol estimating aerosol lifetimes ages
2009/3/12
Aerosol variability is examined as function of particle size for data collected over the Northern Indian Ocean in February 1999 as part of the INDOEX experiment. It was found that for particles believ...
Estimating the contribution of bromoform to stratospheric bromine and its relation to dehydration in the tropical tropopause layer
bromoform stratospheric bromine dehydration tropical tropopause layer
2009/1/16
The contribution of bromoform to the stratospheric bromine loading is estimated using the one-dimensional tropical mean model of Folkins and Martin (2005), which is constrained by observed mean profil...
A group contribution method for estimating the vapour pressures of α-pinene oxidation products
contribution method vapour pressures α-pinene oxidation products
2009/1/7
A prediction method based on group contribution principles is proposed for estimating the vapour pressure of α-pinene oxidation products. Temperature dependent contributions are provided for the foll...
Application of positive matrix factorization in estimating aerosol secondary organic carbon in Hong Kong and its relationship with secondary sulfate
positive matrix factorization aerosol secondary organic carbon Hong Kong secondary sulfate
2008/12/30
Secondary organic carbon (SOC) is often a significant portion of organic carbon (OC) in ambient particulate matter (PM). The levels and seasonal patterns of SOC in Hong Kong were examined using more t...
Estimating the NH3:H2SO4 ratio of nucleating clusters in atmospheric conditions using quantum chemical methods
NH3:H2SO4 quantum chemical methods
2008/12/10
We study the ammonia addition reactions of H2SO4·NH3 molecular clusters containing up to four ammonia and two sulfuric acid molecules using the ab initio method RI-MP2 (Resolution of Identity 2nd orde...
