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 کاملAerosol Optical Thickness Retrieval over Land: the Atmospheric Correction Based on the Meris L2 Reflectance
RESUME The MERIS L2 reflectance of the data product requires over land surface an atmospheric correction for the aerosol effect. For this purpose the determination of aerosol optical thickness will be done by the BAER (Bremen AErosol Retrieval) approach, modified for this type of data product. Validation and application of the retrieval of spectral aerosol optical thickness and its application ...
متن کاملA Surface Reflectance Model for Aerosol Remote Sensing over Land
Aerosol remote sensing over land is based on the use of pixels covered by vegetation. Because of the absorption of the photosynthesis pigments, these pixels are quite dark in the blue and in the red. This consideration led to introduce the concept of DDV pixels. Initially, 11 DDV models have been selected from the POLDER 1 imagery. ARVI, atmospherically resistant vegetation index, has been used...
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 کاملDetermination of fine particulate matter from MERIS and SeaWiFS aerosol data
1 ABSTRACT Over land, the Dense Dark Vegetation is used to derive in a first stage the aerosol path radiance and in a second stage to propose an aerosol product which consists of the aerosol optical thickness at 443 nm. Air quality monitoring of the particles is based on measurements of PM10 and PM2.5 which are respectively the density of particles of diameter lesser than 10 μm, lesser than 2.5...
