GLS tracking locations + time-matched front metrics

All original GLS tracking locations, plus associated 7-day front thermal and chlorophyll-a front metrics (Thermal metrics = thermal front density, Tdens5; thermal front gradient density, Tgdens5; thermal front persistence, Tpfront; distance to closest thermal front (km), Tdist; side of thermal front, Tside; Chlorophyll-a metrics = chl-a front density, Cdens5; chl-a front gradient density, Cgdens5; persistence of chl-a front, Cpfront; distance to closest chl-a front, Cdist; side of chl-a front, Cside).

本数据集包含全部原始GLS追踪位点，以及关联的7天尺度热锋与叶绿素a锋面特征参数。其中热学特征参数包括：热锋密度（thermal front density, Tdens5）、热锋梯度密度（thermal front gradient density, Tgdens5）、热锋持续性（thermal front persistence, Tpfront）、至最近热锋的距离（单位：千米，Tdist）与热锋所在侧（Tside）；叶绿素a锋面特征参数包括：叶绿素a锋密度（chl-a front density, Cdens5）、叶绿素a锋梯度密度（chl-a front gradient density, Cgdens5）、叶绿素a锋持续性（persistence of chl-a front, Cpfront）、至最近叶绿素a锋的距离（Cdist）与叶绿素a锋所在侧（Cside）。
