  • SRID 4326 of two available coordinate systems. GIS data for offshore wind speed (meters/second). Specified to Exclusive Economic Zones (EEZ).Wind resource based on NOAA blended sea winds and monthly wind speed at 30km resolution, using a 0.11 wind sheer to extrapolate 10m - 90m. Annual average >= 10 months of data, no nulls. Units:m/s at 90m ASL. Source: National Renewable Energy Laboratory (NREL)

  • Project financed by the Spanish Agency of International Cooperation for Development (AECID) and the Government of Navarra in collaboration with the Government of Tunisia through the agency, Agence Nationale pour la Maîtrise de l'Energie (ANME). The project started at the end of 2004 and was finished at the beginning of 2009. Wind maps are generated in GIS format at 1 km x 1 km resolution at different heights: 10m, 60m, 80m, and 100m. Validation: The wind map has been validated at the 17 meteorological stations installed for this project and also with 19 selected stations operated by Institut National de la Météorologie (with measurements at 10m). The results show a very accurate estimation of the average wind speed. The global Bias (error calculated between the calculated wind speed and the measured wind speed at the meteorological stations) is 0 m/s at 10m height, 0.04 m/s at 20m height and 0.23 m/s at 40m height. Wind map methodology: Mesoscale model SKIRON was used to simulate the wind over Tunisia. 5 years of hourly simulations were used to build the map. This model is based on the ETA model developed by the National Centers for Environmental Prediction (NCEP)of the USA. The model is operational since 1993. The methodology to calculate wind maps with SKIRON was developed between CENER and the University of Athens, and it has been validated in Spain, Portugal, Poland and Tunisia.

  • Wind map is calculated, by simulating the atmosphere conditions with SKIRON mesoscale model. GFS 12 UTC cycle, from NCAR/NCEP is used as input. The period simulated is since June-2003 until June-2012. SKIRON long-term simulation is launched to cover the entire 9 years, generating hourly maps to the entire simulated period. With this output Iraq wind map is computed averaging 100 meters Weibull parameter A from the nine years. Typically the grid horizontal resolution is 0.05 x 0.05 and has 50 vertical levels.

  • Power density map is calculated, by simulating the atmosphere conditions with SKIRON mesoscale model. GFS 12 UTC cycle, from NCAR/NCEP is used as input. The period simulated is since June-2003 until June-2012. SKIRON long-term simulation is launched to cover the entire 9 years, generating hourly maps to the entire simulated period. Wind power density is calculated for every hour along the period simulated, taking into account hourly pressure and temperature simulated by the model. It means no standard air density is assumed. Then power density map is computed averaging 50 meters power density from the nine years. Typically the grid horizontal resolution is 0.05 x 0.05 and has 50 vertical levels
