Technical Note: Propagating correlations in atmospheric inversions using different Kalman update smoothers
atmospheric Kalman update smoothers Technical Note
2011/2/25
The scheme to propagate correlations between on-line and off-line state variables in atmospheric inversions using the fixed-lag Kalman smoother proposed in Bruhwiler et al. (2005) is explained as a pr...
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...
Different characteristics of char and soot in the atmosphere and their ratio as an indicator for source identification in Xi'an, China
atmosphere indicator source identification Xi'an China
2010/2/1
Numerous definitions and analytical techniques for elemental (or black) carbon (EC) have been published in the scientific literature, but still no generally accepted interdisciplinary definition exist...
Tropospheric ozone from IASI: comparison of different inversion algorithms and validation with ozone sondes in the northern middle latitudes
Tropospheric ozone IASI ozone sondes northern middle latitudes
2009/12/31
This paper presents a first statistical validation of tropospheric ozone products derived from measurements of the IASI satellite instrument. Since the end of 2006, IASI (Infrared Atmospheric Sounding...
Sensitivity studies of different aerosol indirect effects in mixed-phase clouds
different aerosol indirect effects mixed-phase clouds
2009/12/3
Aerosols affect the climate system by changing cloud characteristics. Using the global climate model ECHAM5-HAM, we investigate different aerosol effects on mixed-phase clouds: The glaciation effect, ...
The radiative forcing potential of different climate geoengineering options
radiative forcing potential different climate geoengineering options
2009/8/7
Climate geoengineering proposals seek to rectify the Earth's current and potential future radiative imbalance, either by reducing the absorption of incoming solar (shortwave) radiation, or by removing...
Studies of heterogeneous freezing by three different desert dust samples
heterogeneous freezing desert dust samples
2009/5/6
We present results of experiments at the aerosol interactions and dynamics in the atmosphere (AIDA) chamber facility looking at the freezing of water by three different types of mineral particles at t...
On the relationship between acetone and carbon monoxide in different air masses

2009/3/11
Carbon monoxide and acetone measurements are presented for five aircraft measurement campaigns at mid-latitudes, polar and tropical regions in the northern hemisphere. Throughout all campaigns, free t...
Impact of different emission inventories on simulated tropospheric ozone over China: a regional chemical transport model evaluation
different emission inventories simulated tropospheric ozone China regional chemical transport model
2009/2/27
The importance of emission inventory uncertainty on the simulation of summertime tropospheric ozone over China has been analyzed using a regional chemical transport model. Three independent emissions ...
