US National Aeronautics and Space Administration (NASA) Global Modeling and Assimilation Office (GMAO) Modern-Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) tavgM_2d_slv_Nx: 2-dimensional Monthly mean, Time-Averaged, Single-Level, Assimilation, Single-Level Diagnostics

A monthly time-averaged 2-dimensional data collection of surface-level, meteorological parameters are available in the Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2). It contains global model and data assimilation results that incorporate satellite-based observations to predict monthly, surface-level, atmospheric meteorological parameters such as air temperature, wind components, sea level pressure, surface pressure, and total precipitable water vapor.

现代气候研究与应用再分析资料第二版（Modern-Era Retrospective analysis for Research and Applications version 2, MERRA-2）提供了近地面气象参数的逐月时间平均二维数据集。该数据集包含融合卫星观测资料的全球模式与数据同化成果，可输出逐月尺度的近地面大气气象参数，具体包括气温、风场分量、海平面气压、地面气压及总可降水量。
