Regional Ocean Modeling System (ROMS): Guam: 2-D Variables

Regional Ocean Modeling System (ROMS) 6-day, 3-hourly forecast for the region surrounding Guam and parts of the Commonwealth of the Northern Mariana Islands (CNMI) at approximately 2-km resolution. Boundary conditions provided by the wider ROMS model for the region surrounding the Western North Pacific (roms_mari) at approximately 4-km resolution. Atmospheric forcing generated by the Weather Research and Forecasting (WRF) model for the region surrounding Guam and parts of the Commonwealth of the Northern Mariana Islands (CNMI) (wrf_guam) at approximately 3-km resolution. Tide forcing uses the Oregon State University (OSU) Tidal Prediction Software (OTPS) TOPEX/Poseidon global inverse solution (TPXO) to derive barotropic tidal elevation and velocity. Data are assimilated over the previous 3 days using all available observations to improve the model estimate of current ocean state (its nowcast) before forecasts are run. Assimilated observations may include satellite-based sea surface temperatures from MODIS, AVHRR, or OSTIA; satellite-based sea surface height from AVISO; and in-situ water temperature and salinity profiles from ARGO floats. While considerable effort has been made to implement all model components in a thorough, correct, and accurate manner, numerous sources of error are possible. As such, please use these data with the caution appropriate for any ocean related activity.

区域海洋模拟系统（ROMS）针对关岛及周边及北马里亚纳群岛联邦（CNMI）部分地区提供的6天、3小时预报数据，分辨率约为2公里。西部北太平洋（roms_mari）周边区域由更广泛的ROMS模型提供的边界条件，分辨率约为4公里。关岛及周边及北马里亚纳群岛联邦（CNMI）部分地区的大气强迫由天气研究预报（WRF）模型生成，分辨率约为3公里。潮汐强迫采用俄勒冈州立大学（OSU）潮汐预测软件（OTPS）的TOPEX/Poseidon全球逆解（TPXO）推导出非潮汐潮高和流速。数据通过过去3天的所有可用观测数据同化，以改进模型对当前海洋状态的估计（即即时预报）并在进行预报之前进行。同化的观测数据可能包括来自MODIS、AVHRR或OSTIA的基于卫星的海洋表面温度；来自AVISO的基于卫星的海洋表面高度；以及来自ARGO浮标的现场水温盐度剖面。尽管已竭尽全力以详尽、准确的方式实施所有模型组件，但仍可能存在多种误差来源。因此，请谨慎使用这些数据，适用于任何海洋相关活动。
