Current Meter Data from the Sargasso Sea, July 1977 to August 1978 (POLYMODE)

This data set consists of discrete daily measurements of zonal and meridional
components of currents were made at 19 points at 4 depth levels (100, 400, 700
and 1,400 meters) in the Sargasso Sea. Low pass filtering was employed to
estimate synoptic variability in the ocean. For each level and each day stream
function is computed with the Gandin optimal interpolation method. Data were
collected during the USSR-USA POLYMODE Experiment (July 1977 to August 1978). A
books with sets of components and stream pictures for each 2 days is available.

本数据集包含马尾藻海（Sargasso Sea）内19个测点、4个深度层（100米、400米、700米及1400米）的海流纬向分量与经向分量逐日离散观测数据。研究采用低通滤波方法估算海洋的天气尺度变率。针对每个深度层与每日观测数据，采用甘丁最优插值法（Gandin optimal interpolation method）计算流函数。本数据集采集于美苏POLYMODE实验期间（1977年7月至1978年8月）。另有配套手册收录了每2日的海流分量数据集与流场图像集。
