Intra-Seasonal Variability of Aerosols and Their Radiative Impacts on Sahel Climate during the Period 2000-2010 Using AERONET Data
AERONET Aerosol Optical Depth Radiative Forcing
2013/3/11
This paper presents a study using in situ measurements (AERONET data) to characterize the intra-seasonal variability of aerosols and their shortwave radiative impacts on Sahel (11N - 18N and 20W - 15E...
Inferring absorbing organic carbon content from AERONET data
organic carbon content AERONET data
2011/1/19
Black carbon, light-absorbing organic carbon (often called "brown carbon") and mineral dust are the major light-absorbing aerosols. Currently the sources and formation of brown carbon aerosol in parti...
Applying an ensemble Kalman filter to the assimilation of AERONET observations in a global aerosol transport model
Kalman filter assimilation AERONET observations global aerosol transport model
2010/3/16
We present a global aerosol assimilation system based on an Ensemble Kalman filter, which we believe leads to a significant improvement in aerosol fields. The ensemble allows realistic, spatially and ...
Absorption Angstrom Exponent in AERONET and related data as an indicator of aerosol composition
AERONET indicator aerosol composition
2010/2/21
Recent results from diverse air, ground, and laboratory studies using both radiometric and in situ techniques show that the fractions of black carbon, organic matter, and mineral dust in atmospheric a...
Aerosol characterization in Northern Africa, Northeastern Atlantic, Mediterranean Basin and Middle East from direct-sun AERONET observations
Aerosol characterization Northern Africa Northeastern Atlantic Mediterranean Basin Middle East direct-sun AERONET observations
2009/11/19
We provide an atmospheric aerosol characterization for North Africa, Northeastern Atlantic, Mediterranean and Middle East based on the analysis of quality-assured direct-sun observations of 39 station...
Size-segregated mass distributions of aerosols over Eastern Mediterranean: seasonal variability and comparison with AERONET columnar size-distributions
aerosols Eastern Mediterranean AERONET columnar
2008/12/10
This work provides long-term (2004–2006) size segregated measurements of aerosol mass at a remote coastal station in the southern Europe, with the use of size-selective samplings (SDI impactor). Seven...
Classification of aerosol properties derived from AERONET direct sun data

2008/11/28
Aerosol spectral measurements by sunphotometers can be characterized by three independent pieces of information: 1) the optical thickness (AOT), a measure of the column aerosol concentration, 2) the o...
Aerosol direct radiative effect in the Po Valley region derived from AERONET measurements
Aerosol radiative Po Valley AERONET
2008/11/17
The aerosol direct radiative effect (ADRE) affecting the Po Valley and the adjacent North Adriatic Sea is studied using 10-year series of measurements collected at two AERONET sites located in the wes...
Physical and optical aerosol properties at the Dutch North Sea coast based on AERONET observations
optical aerosol properties Dutch North Sea coast AERONET
2008/11/12
Sun photometer measurements at the AERONET station at the North Sea coast in The Hague (The Netherlands) provide a climatology of optical and physical aerosol properties for the area. Results are pres...
