RT journal article T1 The Use of Sentinel-3 Altimetry Data to Assess Wind Speed from the Weather Research and Forecasting (WRF) Model: Application over the Gulf of Cadiz A1 Mulero Martínez, Roberto A1 Román Cascon, Carlos A1 Mañanes Salinas, Rafael A1 Izquierdo González, Alfredo A1 Bruno Mejías, Miguel A1 Gómez Enri, Jesús A2 Física Aplicada K1 wind speed K1 satellite altimetry K1 WRF K1 model validation K1 sea surface AB This work presents the quality performance and the capabilities of altimetry derived windspeed (WS) retrievals from the altimeters on-board Copernicus satellites Sentinel-3A/B (S3A/B) forthe spatial assessment of WS outputs from the weather research and forecasting (WRF) model overthe complex area of the Gulf of Cádiz (GoC), Spain. In order to assess the applicability of the altimetrydata for this purpose, comparisons between three different WS data sources over the area wereevaluated: in situ measurements, S3A/B 20 Hz altimetry data, and WRF model outputs. Sentinel-3A/B WS data were compared against two different moored buoys to guarantee the quality of thedata over the GoC, resulting in satisfying scores (average results: RMSE = 1.21 m/s, r = 0.93 for S3Aand RMSE = 1.36 m/s, r = 0.89 for S3B). Second, the WRF model was validated with in situ data fromfour different stations to ensure the correct performance over the area. Finally, the spatial variabilityof the WS derived from the WRF model was compared with the along-track altimetry-derived WS.The analysis was carried out under different wind synoptic conditions. Qualitative and quantitativeresults (average RMSE < 1.0 m/s) show agreement between both data sets under low/high windregimes, proving that the spatial coverage of satellite altimetry enables the spatial assessment ofhigh-resolution numerical weather prediction models in complex water-covered zones.
