“…When radar data quality is good, this approach has been shown to give good results (Wyatt, 2012) except in very low sea-states when the wind and Bragg waves are no longer aligned. Wyatt (2012) quotes RMSDs between radar and measured or modeled wind direction of between 30 and 50 • , but in Wyatt et al (2006) a value of 23 • was found when low sea-states were removed from the analysis. As mentioned above, the second order signal is mostly generated by non-linear waves.…”

“…In general an HFR sends out modulated radio waves and listens to the returned signal, which is mainly affected by the surface waves propagating along radar look direction that are of the order of the transmitted wave length (Bragg scattering). From the measured backscatter several oceanic parameters can be obtained, such as: ocean surface currents (e.g., Paduan and Rosenfeld, 1996;Gurgel et al, 1999;Shrira et al, 2001), waves (e.g., Wyatt et al, 2006), winds (e.g., Shen et al, 2012), tsunami (e.g., Lipa et al, 2006) and discrete targets (ships) (e.g., Maresca et al, 2014).…”

“…In Europe, the number of systems is growing with over 50 HFRs currently deployed and a number in the planning stage. Nowadays, these systems are integrated in many European coastal observatories with proven potential for monitoring (e.g., Wyatt et al, 2006;Molcard et al, 2009;Berta et al, 2014b) and even providing short-term prediction of coastal currents (e.g., Orfila et al, 2015;Solabarrieta et al, 2016;Vilibić et al, 2016), and inputs for data assimilation and the validation and calibration of numerical ocean forecasting models, especially near the coast (e.g., Barth et al, 2008Barth et al, , 2011Marmain et al, 2014;Stanev et al, 2015;Iermano et al, 2016). The growing number of HFRs, the optimization of HFR operation against technical hitches and the need for complex data processing and analysis, highlight the urgent requirement to increase the coordination in the HFR community.…”

High Frequency Radar (HFR) is a land-based remote sensing instrument offering a unique insight to coastal ocean variability, by providing synoptic, high frequency and high resolution data at the ocean atmosphere interface. HFRs have become invaluable tools in the field of operational oceanography for measuring surface currents, waves and winds, with direct applications in different sectors and an unprecedented potential for the integrated management of the coastal zone. In Europe, the number of HFR networks has been showing a significant growth over the past 10 years, with over 50 HFRs currently deployed and a number in the planning stage. There is also a growing literature concerning the use of this technology in research and operational oceanography. A big effort is made in Europe toward a coordinated development of coastal HFR technology and its products within the framework of different European and international initiatives. One recent initiative has been to make an up-to-date inventory of the existing HFR operational systems in Europe, describing the characteristics of the systems, their operational products and applications. This paper offers a comprehensive review on the present status of European HFR network, and discusses the next steps toward the integration of HFR platforms as operational components of the European Ocean Observing System, designed to align and integrate Europe's ocean observing capacity for a truly integrated end-to-end observing system for the European coasts.

“…However, wind flow distortion due to the superstructure or the movement of the anemometer platform may affect wind measurements [1], and the employment of buoys may be limited by the surrounding environment [2]. Complementing the point measurements of such in-situ sensors, remote-sensing instruments such as synthetic aperture radar (SAR) [3][4][5], high frequency (HF) radar [6][7][8], and X-band marine radar [9][10][11][12] have been developed as alternative approaches over the last few decades. Particularly, X-band marine radar has been rapidly developed as an ocean remote sensor since it can image both the spatial and temporal variations of the sea surface with high resolutions.…”

Ocean Wind and Wave Measurements Using X-Band Marine Radar: A Comprehensive Review

2017

Ocean wind and wave parameters can be measured by in-situ sensors such as anemometers and buoys. Since the 1980s, X-band marine radar has evolved as one of the remote sensing instruments for such purposes since its sea surface images contain considerable wind and wave information. The maturity and accuracy of X-band marine radar wind and wave measurements have already enabled relevant commercial products to be used in real-world applications. The goal of this paper is to provide a comprehensive review of the state of the art algorithms for ocean wind and wave information extraction from X-band marine radar data. Wind measurements are mainly based on the dependence of radar image intensities on wind direction and speed. Wave parameters can be obtained from radar-derived wave spectra or radar image textures for non-coherent radar and from surface radial velocity for coherent radar. In this review, the principles of the methodologies are described, the performances are compared, and the pros and cons are discussed. Specifically, recent developments for wind and wave measurements are highlighted. These include the mitigation of rain effects on wind measurements and wave height estimation without external calibrations. Finally, remaining challenges and future trends are discussed.
