Methodology:
From the JRC-MARS gridded agro-meteorological database, meteorological observations of daily air temperature at station level with data available for last 30 years (1985-2014) have been selected. The WOFOST crop model has been used to estimate the day of occurrence of the flowering of winter wheat. The input data for crop model simulations were taken from JRC-MARS crop database: the date of emergence, the temperature sum required to reach flowering, and the base temperature below which crop development stops. Linear trend coefficients of the day of occurrence of flowering for the period 1985-2014 were calculated at all stations selected. Then the trend coefficients were spatially interpolated onto the regular 25 km JRC-MARS grid using the thin plate spline method.
