I have downloaded "MERRA2_100.tavgU_2d_lnd_Nx.198001.nc4" evaporation data from 1980 to year 2020.
"MERRA-2 tavgU_2d_lnd_Nx: 2d,diurnal,Time-Averaged,Single-Level,Assimilation,Land Surface Diagnostics V5.12.4 (M2TUNXLND)"
Each data has 24 layers (i guess these are hours), but i want to know the units??? i need output evaporation in mm/month? Can anyone help??
"M2TUNXLND is monthly mean diurnal , i.e., the average is done for each hour of a month.
If you are interested in the monthly mean data, you should have data for M2TMNXLND.
For the variable EVLAND, the unit is: kg m-2 s -1
Read more by searching M2T1NXLND or searching the variable name in
kg m-2 s -1 = mm/s
EVLAND *3600*24*<day_of_mon> --> mm/month"
