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 کاملCalibration Status of the Aatsr Reflectance Channels
The radiometric gains of the AATSR visible to shortwave-infrared channels are calibrated using an on-board solar diffuser. The on-board calibration is supported by vicarious techniques such as comparisons over stable desert targets to establish relative biases in the radiometric calibrations of AATSR and other optical sensors and also to determine the long-term drifts. The authors present the r...
متن کاملComparisons of IASI-A and AATSR measurements of top-of-atmosphere radiance over an extended period
This study examines the trustworthiness of the Advanced Along-Track Scanning Radiometer (AATSR) and the Infrared Atmospheric Sounding Interferometer (IASIA), as on-orbit reference instruments that are useful in recalibrating the Advanced Very High Resolution Radiometer (AVHRR) series (Mittaz and Harris, 2011). To do this, a 39month period (1 January 2008 to 31 March 2011) of AATSR and IASI-A in...
متن کاملSciamachy Reflectance and Solar Irradiance Validation
The top-of-atmosphere spectral reflectance measured by SCIAMACHY has been validated by comparisons between calibrated SCIAMACHY V6 Level 1 data and corresponding reflectances from AATSR and MERIS. The AATSR analysis is currently restricted to part of one specifically processed orbit containing a scene over a hurricane with high and homogeneous clouds for which results for V5 data are already av...
متن کاملMeris O2 Calibration Using Sciamachy Measurements
A new MERIS spectral calibration method is proposed exploiting the synergy between MERIS and SCIAMACHY ENVISAT instruments. Detailed method description and preliminary results are presented in this paper. In the O2 calibration mode MERIS is measuring atmospheric radiances in the 750-780 nm spectral range in order to verify the instrument ability to reproduce position and shape of O2 band-A abso...
