Improved stratospheric aerosol extinction profiles from SCIAMACHY: validation and sample results
Stratospheric aerosol extinction profiles have been retrieved from SCIAMACHY/Envisat measurements of limb-scattered solar radiation. The retrieval is an improved version of an algorithm presented earlier. The retrieved aerosol extinction profiles are compared to co-located aerosol profile measurements from the SAGE II solar occultation instrument at a wavelength of 525 nm. Comparisons were carr...
متن کاملValidation of SCIAMACHY top-of-atmosphere reflectance for aerosol remote sensing using MERIS L1 data
Aerosol remote sensing is very much dependent on the accurate knowledge of the top-of-atmosphere (TOA) reflectance measured by a particular instrument. The status of the calibration of such an instrument is reflected in the quality of the aerosol retrieval. Current data of the SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) instrument (operated with the data pr...
متن کاملSciamachy Toa Reflectance Correction Effects on Aerosol Optical Depth Retrieval
Aerosol retrieval from SCIAMACHY data processing at ISAC-CNR has been carried-out to retrieve Aerosol Optical Depth (AOD) at 500 nm wavelength together with a parameter (class) which defines a set of chemico-physical properties pertaining to suspended particles. SCIAMACHY Level 1B data from nadir measurements both over ocean and land are used as input for this processor. SCIAMACHY, onboard ENVI...
متن کاملImproved Sciamachy Wfdoas Total Ozone Retrieval: Steps towards Homogenising Long-term Total Ozone Datasets from Gome, Sciamachy, and Gome2
Currently three European satellite spectrometers, GOME1/ERS2 (1995-present), SCIAMACHY/ENVISAT (2002-present), and GOME2 (2006-present) provide a near global decadal data set of total ozone covering more than a decade. This data are very valuable for the detection of recovery in stratospheric ozone as expected from the levelling off of stratospheric chlorine. In order to detect such a signal be...
متن کاملStratospheric and tropospheric NO2 variability on the diurnal and annual scale: a combined retrieval from ENVISAT/SCIAMACHY and solar FTIR at the Permanent Ground-Truthing Facility Zugspitze/Garmisch
Columnar NO2 retrievals from solar FTIR measurements at the Zugspitze (47.42 N, 10.98 E, 2964 m a.s.l.), Germany were investigated synergistically with columnar NO2 retrieved from SCIAMACHY data by the University of Bremen scientific algorithm UB1.5 for the time span July 2002–October 2004. A new concept to match FTIR data to the time of satellite overpass makes use of the NO2 daytime increasin...
