NorCPM coupled reanalysis data for ocean biogeochemistry
收藏资源简介:
This dataset contains coupled reanalysis data for ocean biogeochemistry, generated through improved version of the NorCPM data assimilation system. The system assimilates monthly observations of sea surface temperature (SST) and temperature-salinity (TS) profiles using EnKF algorithm. The reanalysis utilized the medium-resolution Norwegian Earth System Model version 1 (NorESM1-ME), with biogeochemical (BGC) parameters optimized through EnKF data assimilation. The dataset spans globally and covers the timeframe from January 1, 1985, to December 31, 2022.
本数据集包含海洋生物地球化学耦合再分析数据,由改进版NorCPM数据同化系统生成。该系统采用集合卡尔曼滤波(Ensemble Kalman Filter, EnKF)算法,同化海表温度(Sea Surface Temperature, SST)与温盐(Temperature-Salinity, TS)廓线的月度观测数据。本次再分析采用中等分辨率的挪威地球系统模式第1版(NorESM1-ME),并通过EnKF数据同化优化了生物地球化学(Biogeochemical, BGC)参数。本数据集覆盖全球范围,时间跨度为1985年1月1日至2022年12月31日。
