The MERIS Terrestrial Chlorophyll Index (MTCI) is designed to monitor vegetation condition via an estimation of chlorophyll content. Its simplicity of calculation, suitability for automation and most importantly, sensitivity to all and notably, high values of chlorophyll content made it a suitable level-2 ESA product. This index effectively combines information on leaf area index and the chloro...

A-MODIS, AATSR, MERIS, POLDER-3 and SeaWiFS data are directly compared at top of the atmosphere level for nearly concomitant observation carried out under nearly identical or reciprocal geometries. Comparisons are carried out over the Salar de Uyuni in Bolivia. The results indicate that MERIS and A-MODIS are radiometrically in line. In comparison to these sensors, the SeaWiFS data exhibit a sys...

Although remote sensing technology has been widely used to monitor inland water bodies; the lack of suitable data with high spatial and spectral resolution has severely obstructed its practical development. The objective of this study is to improve the unmixing-based fusion (UBF) method to produce fused images that maintain both spectral and spatial information from the original images. Images ...

The absorption coefficient of phytoplankton, detrital material and coloured dissolved organic material and Chl a concentrations were collected during cruises in 2002 & 2003 under the framework of the European Research Contract The Regional Validation of MERIS chlorophyll products in North Sea coastal waters (REVAMP, EVG1-CT-200100049). Three campaigns were undertaken in coastal regions of the N...

the main limitation of radar interferometry in measuring ground displacements is due to phase propagation delays caused by the troposphere. tropospheric water vapor is a major limitation for high precision interferometric synthetic aperture radar (insar)applications. using global meteorological reanalysis models and merisdata are two methods that can be used for correcting the effects of the tr...

The MEdium Resolution Imaging Spectrometer (MERIS) can be used to monitor vegetation dynamics at regional to global scales. However, the spatial resolutions provided by this sensor (300 or 1200 m) might not be appropriate to monitor fragmented landscapes. This is why the synergistic use of MERIS full resolution (300 m) and a high spatial resolution land use/land cover database (25 m) is studied...

Assessing the regional vegetation dynamics in the Iberian Peninsula (IP) is a key issue in the context of the carbon cycle at the southern Europe ecosystems. The estimation of net ecosystem production (NEP) was conducted by a productivity ecosystem model, the Carnegie Ames Stanford Approach (CASA) model, based on MODIS fraction of absorbed photosynthetically active radiation (fAPAR) and leaf ar...

Informative spectral bands for green leaf area index (LAI) estimation in two crops were identified and generic models for soybean and maize were developed and validated using spectral data taken at close range. The objective of this paper was to test developed models using Aqua and Terra MODIS, Landsat TM and ETM+, ENVISAT MERIS surface reflectance products, and simulated data of the recently-l...

This paper describes the results of a feasibility study to test the usefulness of MERIS for land cover mapping. The Netherlands was used as a test site because of its highly fragmented landscape. Results showed that the geometric and radiometric properties of the studied MERIS images of the Netherlands are suitable for land applications. Calculation of principal components and correlation coeff...
