Regional Ocean Modeling System (ROMS) 1km Model, De Soto Canyon, January 2010-March 2013

This data is from a ROMS (http://www.myroms.org) free-running simulation of the De Soto Canyon region in the North East Gulf of Mexico. The simulation covers the time span January 2010 through March 2013. The vertical grid is stretched to focus vertical resolution near the surface and the horizontal grid has 1km resolution. CFSR data are used for the surface forcing and the model is nested in a data-assimilative global HYCOM model. Rivers are included through point sources with temperature, salinity and momentum fluxes specified and derived from USGS and NOAA data.

本数据集源自针对墨西哥湾东北部德索托峡谷区域开展的ROMS（Regional Ocean Modeling System，http://www.myroms.org）自由运行数值模拟。该模拟的时间跨度为2010年1月至2013年3月，其垂直网格采用拉伸设计以强化表层附近的垂直分辨率，水平网格分辨率达1千米。海面强迫场采用CFSR（Climate Forecast System Reanalysis）数据，模型嵌套于具备数据同化能力的全球HYCOM（Hybrid Coordinate Ocean Model）模型中。模拟通过点源方式纳入河流过程，其温度、盐度与动量通量均已预设，数据源自美国地质调查局（USGS）及美国国家海洋和大气管理局（NOAA）的观测资料。
