Retrieval of Land Surface Reflectance and Albedo from Meris Data
An atmospheric correction algorithm for the retrieval of land surface reflectance from the Medium Resolution Imaging Spectrometer (MERIS) data has been implemented. The algorithm is designed to obtain the main atmospheric parameters needed in the correction from the image itself, leading to an optimal characterization of the atmospheric state, in temporal and spatial resolution terms. The first...
متن کاملMeris Land Products Validation
Over land, the aerosol remote sensing is based on the observation of Dense Dark Vegetation (DDV) and this concept is applied on MERIS with a spectral index (ARVI, Atmospherically Resistant Vegetation Index) to detect the DDV and the use of the bands at 412, 443 and 670 nm to characterize the aerosols. The aerosol size distribution is assumed to follow the Junge law while the aerosol refractive ...
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...

متن کاملObject-based Dimensionality Reduction in Land Surface Phenology Classification
Unsupervised classification or clustering of multi-decadal land surface phenology provides a spatio-temporal synopsis of natural and agricultural vegetation response to environmental variability and anthropogenic activities. Notwithstanding the detailed temporal information available in calibrated bi-monthly normalized difference vegetation index (NDVI) and comparable time series, typical pre-c...
