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...
Divergence of sun-rays by atmospheric refraction at large solar zenith angles
sun-rays atmospheric refraction large solar zenith angles
2009/3/4
For the determination of photolysis rates at large zenith angles it has been demonstrated that refraction by the earth's atmosphere must be taken into account. In fact, due to the modified optical pat...
Inter-comparison of stratospheric O3 and NO2 abundances retrieved from balloon borne direct sun observations and Envisat/SCIAMACHY limb measurements
stratospheric O3 NO2 balloon borne Envisat/SCIAMACHY limb measurements
2009/1/6
Stratospheric O3 and NO2 abundances measured by different remote sensing instruments are inter-compared: (1) Line-of-sight absorptions and vertical profiles inferred from solar spectra in the ultra-v...
Technical Note: Improved total atmospheric water vapour amount determination from near-infrared filter measurements with sun photometers
atmospheric water vapour near-infrared filter measurements sun photometer
2008/12/18
In this work we explore the effect of the contribution of the solar spectrum to the recorded signal in wavelengths outside the typical 940-nm filter's bandwidth. We employ gaussian-shaped filters as w...
Classification of aerosol properties derived from AERONET direct sun data
aerosol properties AERONET sun
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...
