This research explores the possibility of using linear mixture model to generate fraction images from 1km time series NOAA AVHRR monthly composite NDVI data. The percentages of forest, grassland and farmland in the pixels are determined by applying the Constrained Least Squares (CLS) method over the study area in the northeast region of China. The validation of the model for AVHRR monthly compo...

Mit Hilfe von Fernerkundung und zusätzlichen Hilfsdaten sind frühzeitige und objektive Ernteprognosen deutlich vor der Ernte möglich. Dies wurde am Beispiel Braugerste für 2 Regionen in Südwest-Deutschland gezeigt. Demnach können Vorhersagen für Flächenerträge von Braugerste (Sommergerste) bereits 3 – 6 Wochen vor der Ernte vorliegen. Die Prognosefehler, welche abhängig vom Prognosezeitpunkt si...

A new surface boundary forcing dataset for uncoupled simulations with the Community Atmosphere Model is described. It is a merged product based on the monthly mean Hadley Centre sea ice and SST dataset version 1 (HadISST1) and version 2 of the National Oceanic and Atmospheric Administration (NOAA) weekly optimum interpolation (OI) SST analysis. These two source datasets were also used to supply...

This paper considers the effects for offering a "would-notvote" option in contingent valuation (CV) questions framed using the referendum format. This approach arises from a suggestion made by the National Oceanic and Atmospheric Administration's (NOAA) panel on contingent valuation. The NOAA panel was asked to evaluate the use of this method for estimating the economic value of nonmarketed env...
