SST smoothed frontal gradients

An improved automatic detection of mesoscale fronts, derived from Cayula, J. F., & Cornillon, P. (1992) and Cayula, J. F., & Cornillon, P. (1995), using the new method described by Nieto et al. (2012)

基于 Cayula, J. F. 与 Cornillon, P. (1992) 以及 Cayula, J. F. 与 Cornillon, P. (1995) 的研究成果，并采用 Nieto 等人 (2012) 描述的新方法，本研究对中尺度锋面进行了改进的自动检测。Nieto, Karen, Demarcq, H. 和 McClatchie, S. 在其发表于《Remote Sensing of the Environment》的论文《Mesoscale frontal structures in the Canary Upwelling System: new front and filament detection algorithms applied to spatial and temporal patterns》中，介绍了应用于时空模式的新型锋面与细丝检测算法。Cayula, J. F. 与 Cornillon, P. 分别于 1992 年和 1995 年在《Journal of Atmospheric and Oceanic Technology》发表的论文中，提出了针对海洋表面温度图像的边缘检测算法和多图像边缘检测技术。数据集采用网格格式，遵循 CF-1.6 和 ACDD-1.3 标准以及 COARDS 规范。默认的图形查询为 SSTgrad[(1992-08-15)][(18.98355803907279):(60.03469886505636)][(-180.00000317928277):(-108.95010385922009)]&.draw=surface&.vars=longitude|latitude|SSTgrad&.colorBar=BlueWhiteRed|||||3。地理空间范围包括东经 -180.00000317928277 至 -108.95010385922009，北纬 18.98355803907279 至 60.03469886505636，分辨率约为 0.04167 度。数据覆盖时间从 1991 年 1 月 15 日至 2011 年 12 月 15 日。数据源为 NOAA/NMFS/SWFSC。
