Google Earth Engine ——HYCOM 数据子集包含变量海洋温度数据集

The Hybrid Coordinate Ocean Model (HYCOM) is a data-assimilative hybrid isopycnal-sigma-pressure (generalized) coordinate ocean model. The subset of HYCOM data hosted in EE contains the variables salinity, temperature, velocity, and elevation. They have been interpolated to a uniform 0.08 degree lat/long grid between 80.48°S and 80.48°N. The salinity, temperature, and velocity variables have been interpolated to 40 standard z-levels.

The HYCOM Consortium, which includes the National Ocean Partnership Program (NOPP), is part of the U.S. Global Ocean Data Assimilation Experiment (GODAE).

Funded by the National Ocean Partnership Program, the Office of Naval Research (ONR), and DoD High Performance Computing Modernization Program.

混合坐标海洋模型 (HYCOM) 是一种数据同化混合等密度西格玛压力（广义）坐标海洋模型。 EE 中托管的 HYCOM 数据子集包含变量盐度、温度、速度和海拔。它们已被插入到 80.48°S 和 80.48°N 之间的均匀 0.08 度纬度/经度网格。盐度、温度和速度变量已被内插到 40 个标准 z 水平。

HYCOM 联盟，包括国家海洋伙伴计划 (NOPP)，是美国全球海洋数据同化实验 (GODAE) 的一部分。

由国家海洋伙伴计划、海军研究办公室 (ONR) 和国防部高性能计算现代化计划资助。
