Air temperature is one of the main input data of a lot of models, as agro-meteorological models for the water balance monitoring, crops models for yield prediction, or climatological and hydrological models. This variable plays an important role in the energetic and hydro exchanges at the interface between soil, plant and atmosphere.

Many studies of how temperatures affect growth and yield are site-specific and in simulation modelling of land suitability over farms or countries spatial and temporal interpolation of temperatures are required from a sparse network of meteorological recording stations.

In order to obtain spatialized daily minimum temperatures at a high resolution, a contract was funded in the frame of COST Action 79 "Integration of data and methods in agro-climatology" concerning the comparison of several interpolation methods. Different interpolation methods available at Applied Meteorology Foundation (FMA Italy), Meteo France, INRA (France) and DLO (Wageningen, NL) are applied and compared on the 1993 -1994 period in two study areas: south east of France and Tuscany region (Italy).

The final aim is to obtain in an operational way a daily minimum temperature field on a mesh grid scale with the best possible reliability.
