Nowadays, spaceborne Synthetic Aperture Radar (SAR) has become a powerful tool for providing significant wave height (SWH). Traditionally, validation of SAR derived SWH has been carried out against buoy measurements or model outputs, which only yield an inter-comparison, but not an “absolute” validation. In this study, the triple collocation error model has been introduced in the validation of ...

A long-term wave hindcast (1979-2009) based on the NCEP/NCAR Reanalysis and WAVEWATCH III has been assessed using 29 months of measurements over Rio Grande shelf, South Brazil to evaluate skills biases in for this region. Extreme events were selected by Peaks Over Thresholds (POT) fitted a Generalized Pareto Distribution (GPD) estimate extreme significant height from 31 years simulation. The he...

A 29-year wind/wave hindcast is produced over the Mediterranean Sea for period 1990–2018. The dataset obtained by downscaling ERA5 global atmospheric reanalyses, which provide initial and boundary conditions a numerical chain based on limited-area weather wave models: BOLAM, MOLOCH WaveWatch III (WW3) models. In WW3 computational domain, an unstructured mesh used. variable resolutions reach up ...

Nowadays, spaceborne Synthetic Aperture Radar (SAR) has become a powerful tool for providing significant wave height. Traditionally, validation of SAR derived ocean wave height has been carried out against buoy measurements or model outputs, which only yield a inter-comparison, but not an ‘absolute’ validation. In this study, the triple collocation error model has been introduced in the validat...

Abstract. Wind waves play an important role in the climate system, modulating energy exchange between ocean and atmosphere effecting mixing. However, existing ship-based observational networks of wind are still sparse, limiting therefore possibilities validating satellite missions model simulations. In this paper we present data collected on three research cruises North Atlantic Arctic 2020 202...

Resumo Ocorreu um ciclone na costa sul do Brasil entre 30/06/2020 e 01/07/2020, movendo-se continente em direção ao mar. O sistema foi registrado modelos numéricos observações in-situ (boia navio) desde o dia que se formou até dissipar. objetivo deste trabalho é utilizar os dados coletados durante essa condição ambiental extrema uma comparação estatística com modelo atmosférico operacional Glob...
