Evaluation of the MERIS aerosol product over land with AERONET
The Medium Resolution Imaging Spectrometer (MERIS) launched in February 2002 on-board the ENVISAT spacecraft is making global observations of top-ofatmosphere (TOA) radiances. Aerosol optical properties are retrieved over land using Look-Up Table (LUT) based algorithm and surface reflectances in the blue and the red spectral regions. We compared instantaneous aerosol optical thicknesses retriev...

متن کاملFirst Validation of Meris Aerosol Product over Land
The detection of Dense Dark Vegetation (DDV) using the Atmospherically Resistant Vegetation Index (ARVI) and then the aerosol retrieval over DDV are the critical points of the land part of the processing of MERIS images implemented in the level 2 processor. We present here the first validation attempt of the MERIS aerosol product over land by checking its consistency and comparing it to AERONET...
متن کاملEvaluation of VIIRS Land Aerosol Model Selection with AERONET Measurements
The Visible Infrared Imaging Radiometer Suite (VIIRS) is a next-generation polar-orbiting operational environmental sensor with a capability for global aerosol observations. Identifying land aerosol types is important because aerosol types are a basic input in retrieving aerosol optical properties for VIIRS. The VIIRS algorithm can automatically select the optimal land aerosol model by minimizi...
متن کاملA Technique for Aerosol Retrieval over Land from Meris Data
In this paper we present an aerosol retrieval over land algorithm specifically designed for the ENVISAT MERIS sensor, with the aim of the atmospheric correction of the data. The fundamental basis lies on a multiple parameter inversion for spectrally heterogeneous sets of five pixels in a window inside the image, considering invariant the atmosphere in this window. In the modellization of the To...
