This figure shows the rate of change of the flowering date for winter wheat. The flowering date is defined as the day at which a modelization of the winter wheat reaches a development state of 100 in a scale 0 - 200 defined for the WOFOST growth model (Van Keulen H, Wolf J (1986) Modelling of agricultural production: weather soils and crops, Simulation monographs. Pudoc, Wageningen). The map shows the yearly change rate in days per year calculated for the period January 1975 - December 2010.

The map has been produced querying a database internal to Joint Research Centre (JRC) containing crop growth data derived with the WOFOST model (Van Keulen H, Wolf J (1986) Modelling of agricultural production: weather soils and crops,Simulation monographs. Pudoc, Wageningen) These data are derived in the frame of the MARSOP 3 contract, complying with Council Regulation (EC) No 78/2008 of 21 January 2008 on the measures to be undertaken by the Commission in 2008-2013 making use of the remote-sensing applications developed within the framework of the common agricultural policy, Official Journal of the European Union, L 25 of 30 January 2008, p. 1.
