Near-surface velocity 15-day seasonal and annual climatology for the eastern Gulf of Mexico from drifter observations from 1979 to 2015

This dataset contains a seasonal and annual climatology of reconstructed near-surface current data of satellite-tracked 15 m drogued and undrogued drifters observations from February 1979 to June 2015 using the NOAA’s Global Drifter Program for the Gulf of Mexico. The data has a horizontal resolution of 0.125 deg x 0.125 deg. The annual climatological dataset incorporates more than 29 million, six-hour position/velocity estimates scattered throughout the world’s ice-free oceans, from February 1979 to June 2015. The seasonal means used the same data, however, they are 15-days climatological means for different seasons. About 56% of the available data points are from undrogued drifters. Near-surface velocity climatology for the global ocean from drifter observations is available under GRIIDC Unique Dataset Identifier (UDI) R4.x265.000:0013 (DOI: 10.7266/N7SJ1HN5).

本数据集包含基于美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）全球漂流浮标计划（Global Drifter Program）获取的1979年2月至2015年6月期间卫星跟踪的15米级带阻力装置与无阻力装置漂流浮标观测数据所重构的近表层海流季节与年际气候态数据，覆盖墨西哥湾海域。
该数据的水平分辨率为0.125°×0.125°。
年际气候态数据集整合了1979年2月至2015年6月期间分布于全球无冰海洋的超2900万条6小时位置与流速估算数据。
季节平均数据集采用相同的原始观测数据，但其为针对不同季节的15日气候态平均值。
可用数据点中约56%来自无阻力装置漂流浮标。
基于漂流浮标观测的全球近表层流速气候态数据集，可通过全球海洋数据协作组（GRIIDC）唯一数据集标识符（Unique Dataset Identifier, UDI）R4.x265.000:0013（DOI: 10.7266/N7SJ1HN5）获取。
本数据集支撑以下学术成果：Drouin, K. L.、Mariano, A. J.、Ryan, E. H. 与 Laurindo, L. C. 于2019年发表于《海洋污染通报》（Marine Pollution Bulletin）的论文《佛罗里达海峡石油运移轨迹的拉格朗日模拟》，该论文刊载于第140卷，页码范围204–218，DOI为10.1016/j.marpolbul.2019.01.031。
