The development of appropriate ground-based validation techniques is critical to assessing uncertainties associated with satellite data-based products. In this paper, the second of a two-part series, we present a method for validation of the Moderate Resolution Imaging Spectroradiometer Leaf Area Index (MODIS LAI) product with emphasis on the sampling(More)
The development of appropriate ground-based validation techniques is critical to assessing uncertainties associated with satellite data-based products. Here we present a method for validation of the Moderate Resolution Imaging Spectroradiometer (MODIS) Leaf Area Index (LAI) product with emphasis on the sampling strategy for field data collection.

The interaction of two molecules binding to each other is described by two rate parameters, the association rate parameter k(a) and the dissociation rate parameter k(d). Under standardized conditions these kinetic parameters can be determined by analysis of their interaction in an affinity-based biosensor system, such as BIACORE(R) 3000. The association(More)
This paper presents the concept of a future disaster management system that utilizes the modern telecommunication and navigation technology. The system uses Synthetic Aperture Radar (SAR) data as key information source. Five critical elements are required to establish the system: 1) data acquisition and high-speed data transfer; 2) data processing; 3) data(More)
In this paper the Finnish ENVISAT CAL/VAL-project as well as some results obtained in the project will be presented. The project has three major objectives. One objective is to implement an operational data processing chain, the other is to analyze the effect of different ice properties on the SAR signature and its statistics mainly through empirical(More)
