Hi, I tried to do the vertical regridding for the MERRA-2 inst3_3d_asm_Nv: 3d,3-Hourly,Instantaneous,Model-Level,Assimilation,Assimilated Meteorological Fields 0.625 x 0.5 degree V5.12.4 (M2I3NVASM). The vertical regridding requires the ak and bk values for the mid layers and layer interfaces. The MERRA-2 file specification document does not provide the ak bk values. Would you please let me know where I can find the ak bk values for the MERRA-2 data? Thanks!
