The impact of SCIAMACHY near-infrared instrument calibration on CH4 and CO total columns
SCIAMACHY near-infrared instrument calibration CH4 CO total columns
2009/2/17
The near-infrared spectra measured with the SCIAMACHY instrument on board the ENVISAT satellite suffer from several instrument calibration problems. The effects of three important instrument calibrati...
Iterative maximum a posteriori (IMAP)-DOAS for retrieval of strongly absorbing trace gases: Model studies for CH4 and CO2 retrieval from near infrared spectra of SCIAMACHY onboard ENVISAT
(IMAP)-DOAS trace gases CH4 CO2 infrared spectra SCIAMACHY onboard ENVISAT
2009/1/23
In the past, differential optical absorption spectroscopy (DOAS) has mostly been employed for atmospheric trace gas retrieval in the UV/Vis spectral region. New spectrometers such as SCIAMACHY onboard...
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...
Modelling the direct effect of aerosols in the solar near-infrared on a planetary scale

2008/12/12
We used a spectral radiative transfer model to compute the direct radiative effect (DRE) of natural plus anthropogenic aerosols in the solar near-infrared (IR), between 0.85–10 μm, namely, their effec...
