 We can have a problem with one type of file, for example we think that snowpack melts all the snow in some lake grid cells. So, SNOWPACK should be fixed, but meanwhile we can just try to __hack it__. To do it we can change the land use of these grid cells to grass (the most similar to lakes). That can be easily do it to the geo_em files as:
 ```
 module load NCO
+cp geo_em.d02.nc geo_em.d02_old.nc
 ncap2 -s 'where(LU_INDEX == 21) LU_INDEX=10' geo_em.d02_old.nc geo_em.d02.nc
 ./metgrid.exe 
 ```
