Evaluation of EPI forecasting model with inclusion of uncertainty in input value and traceable calibration

Phytopathologies affecting viticulture, such as grapevine downy mildew (Plasmopara viticola), are depending on meteorological trend.
Diseases are controlled with the use of fungicides, which has considerable economic costs, negative effects on environment, human
health and wine quality. This strategy should be reconsidered through introducing methods to reduce the use of chemicals. In order to
act promptly, it is necessary to know the correct incubation period and an accurate knowledge of meteorological parameters such as
temperature, humidity and precipitation is required. This project is an example of metrological approach applied to agrometeorological
studies. The aims are: improvement of the meteorological observations in field by applying a metrological approach and calibration
methods; evaluation of the uncertainties; implementation of traceability in meteorological measurements; and improvement of the
forecasting models by inclusion of measurement uncertainties in the input values.
