Laboratory investigations of the impact of mineral dust aerosol on cold cloud formation
mineral dust aerosol cold cloud formation Laboratory
2010/12/28
Dust particles represent a dominant source of particulate matter (by mass) to the atmosphere, and their emission from some source regions has been shown to be transported on regional and hemispherical...

Cloud thermodynamic phase merged POLDER and MODIS data
2010/12/28
The global spatial and diurnal distribution of cloud properties is a key issue for understanding the hydrological cycle, and critical for advancing efforts to improve numerical weather models and gene...
Stratocumulus cloud thickening beneath layers of absorbing smoke aerosol
Stratocumulus cloud smoke aerosol
2010/12/28
Marine stratocumulus cloud properties, and the free-tropospheric environment above them, are examined in NASA A-Train satellite data for cases where smoke from seasonal burning of the West African sav...
Spectrally-invariant behavior of zenith radiance around cloud edges simulated by radiative transfer
zenith radiance cloud edges radiative transfer
2010/12/20
In a previous paper, we discovered a surprising spectrally-invariant relationship in shortwave spectrometer observations taken by the Atmospheric Radiation Measurement (ARM) program. The relationship ...
Aerosol-cloud interaction determined by both in situ and satellite data over a northern high-latitude site
Aerosol-cloud interaction in situ and satellite data a northern high-latitude site
2010/11/30
The first aerosol indirect effect over a clean, northern high-latitude site was investigated by determining the aerosol cloud interaction (ACI) using three different approaches; ground-based in situ m...
Cosmic rays linked to rapid mid-latitude cloud changes

stratocumulus cloud prediction the Met Office forecast model VOCALS-REx
2010/11/30
Observations in the subtropical southeast Pacific obtained during the VOCALS-REx field experiment are used to evaluate the representation of stratocumulus cloud in the Met Office forecast model and to...
Aerosol effects on ice clouds: can the traditional concept of aerosol indirect effects be applied to aerosol-cloud interactions in cirrus clouds?
Aerosol effects ice clouds aerosol indirect effects aerosol-cloud interactions cirrus clouds
2010/11/29
Cirrus clouds cover approximately 20–25% of the globe and thus play an important role in the Earth's radiation budget. Therefore the effect of aerosols on cirrus clouds can have a substantial impact o...
Laboratory simulation for the aqueous OH-oxidation of methyl vinyl ketone and methacrolein: significance to the in-cloud SOA production
Laboratory simulation the aqueous OH-oxidation methyl vinyl ketone the in-cloud SOA production
2010/10/11
Increasing evidence suggests that secondary organic aerosol (SOA) is formed through aqueous phase reactions in atmospheric clouds. In the present study, the aqueous oxidation of methyl vinyl ketone (M...
Testing remote sensing on artificial observations: impact of drizzle and 3-D cloud structure on effective radius retrievals
remote sensing artificial observations drizzle and 3-D cloud structure effective radius retrievals
2010/10/11
We investigate two types of marine cloud situations each with and without drizzle from LES simulations: (1) a typical daytime stratocumulus deck at two times in the diurnal cycle and (2) one scene wit...
Novel method of generation of Ca(HCO3)2 and CaCO3 aerosols and first determination of hygroscopic and cloud condensation nuclei activation properties
