    DOWA

    The Dutch Offshore Wind Atlas (DOWA) provides a 10 year wind climatology for the North Sea.

  6. Monitoring European Climate using Surface Observations

  9. Global distribution of BSRN stations in January 2015. Operational stations produce quality-controlled data and submit data to the central BSRN datavase at AWI in Bremerhaven, Germany.
    Baseline Surface Radiation Network (BSRN)

    The objective of BSRN is to provide top-quality observations of the shortwave and longwave irradiances at the Earth’s surface.
