In the framework of RITMARE a wind network system was developed in December 2013 by CNR-ISAC, Uos. Padova and CNR-IAMC, Uos Oristano in the Gulf of Oristano, Sardinia, Italy. The wind network included the in-situ data from Sardegna-Clima Onlus organization at Oristano, Fenosu, Santa Giusta and Arborea (figure 1, left panel). The wind system was operating until August 2016. An example of the NRT wind field, obtained from the hourly in-situ wind measurements using a method to interpolate sparse data in meteorology (Brocchini et al., 1995) is shown in the right panel of figure 1. All winds are at 10 m of reference height.
The figure 2, representing the time series of five days of wind speed at 10 m height (left panel) and direction (right panel) of the in-situ stations composing the wind network, was updated every hour.
The wind observations were used as support of interpretations and validation of the wind field extracted from SAR (Zecchetto et al., 2016) and as forcing for the oceanographic model of the Gulf of Oristano (Cucco et al., 2016).
