This data set contains thirty-eight fields simulated from the Mosaic land-surface model (LSM) for Phase 2 of the North American Land Data Assimilation System (NLDAS-2). The data are in 1/8th degree grid spacing and range from Jan 1979 to the present. The temporal resolution is hourly. The file format is netCDF (converted from the GRIB format). Mosaic was developed by Koster and Suarez (1994, 1996) to account for subgrid vegetation variability with a tile approach. Each vegetation tile carries its own energy and water balance and soil moisture and temperature. Each tile has three soil layers, w...本数据集包含基于北美陆面数据同化系统第二阶段（North American Land Data Assimilation System Phase 2, NLDAS-2）的马赛克陆面模式（Land Surface Model, LSM）模拟生成的38个变量场。该数据采用1/8度网格间距，时间覆盖范围为1979年1月至今，时间分辨率为逐小时。文件格式为网络通用数据格式（netCDF），该格式由格点二进制格式（GRIB）转换而来。马赛克陆面模式由Koster与Suarez于1994年、1996年开发，旨在通过瓦片方案表征次网格植被变异性。每个植被瓦片均具备独立的能量与水平衡、土壤湿度及温度特性。每个瓦片包含三层土壤，w……
