Table describing the retrievable observations, access url, etc, used to validate atmospheric, wave and SST parameters in model output. Atmospheric measurements come from land-based weather stations, radiosoundings and measurements taken as part of the HyMeX campaign (balloons, airborne measurements, etc). Wave measurements and some atmospheric parameters come from the Lion metocean buoy, and from wave buoys in the CANDHIS network (CEREMA). Ocean parameters come mainly from the Lion buoy and some Lagrangian floats from the ARGO network.
