Název v původním jazyce

Comparison of two interpolation methods for modelling crop yields in ungauged locations

Popis výsledku v původním jazyce

The crop models liked with a weather generator are often used in assessing sensitivity of crop yields to variability and changes in climatic characteristics or in probabilistic crop yields forecasting. In these situations,weather series representing present climate, future climate or weather forecast may be produced by the weather generator, which is typically calibrated using the site-specific weather observations. The problem arises when we want to simulate crop yields for a site, where no observational data are available. Two approaches are tested in this contribution to model yields in such site: 1) Model yield is interpolated from the surrounding stations where the observed weather series are available to run the crop model. 2) The crop model is run with the site specific input parameters (including soil type) and with weather series produced by weather generator whose parameters were interpolated from the surrounding stations. In both cases, we use the nearest neighbours interpol
