Validation 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 کاملEvidence of systematic errors in SCIAMACHY-observed CO2 due to aerosols
SCIAMACHY CO2 measurements show a large variability in total column CO2 over the Sahara desert of up to 10%, which is not anticipated from in situ measurements and cannot be explained by results of atmospheric models. Comparisons with colocated aerosol measurements by TOMS and MISR over the Sahara indicate that the seasonal variation of SCIAMACHY-observed CO2 strongly resembles seasonal variati...
متن کاملAerosol remote sensing over land: A comparison of satellite retrievals using different algorithms and instruments
An inter-comparison study of the aerosol optical thickness (AOT) at 0.55 μm retrieved using different satellite instruments and algorithms based on the analysis of backscattered solar light is presented for a single scene over central Europe on October 13th, 2005. For the first time comparisons have been performed for as many as six instruments on multiple satellite platforms. Ten different alg...
متن کاملThe Mg Ii Solar Activity Proxy Indicator Derived from Gome and Sciamachy
The main purpose of the passive remote sensing instruments GOME and SCIAMACHY is to determine the amount and distribution of a large number of atmospheric trace constituents by measuring Earthshine radiance. In addition solar observations are performed on a regular time grid which offer the possibility to monitor solar variations. This paper summarises the derivation of a proxy solar activity i...
