dear I was lokking for a solution or an example on the internet for quite a time but since haven?t found an answer yet, I'd like to ask a maybe to simple question: I have a large ncdf-file with five dimension. temperature (t2m), the variable against, lat, lon and time. (height is included as well) the structure is [1] "file C:/RDaten/t2m.ETH.HC_A2.nc has 5 dimensions:" [1] "height Size: 1" [1] "rlat Size: 75" [1] "rlon Size: 65" [1] "time Size: 11160" [1] "time_bnds Size: 2" [1] "------------------------" [1] "file C:/RDaten/t2m.ETH.HC_A2.nc has 4 variables:" [1] "float lat[rlon,rlat] Longname:latitude of grid-points Missval:1e+30" [1] "float lon[rlon,rlat] Longname:longitude of grid-points Missval:1e+30" [1] "char rotated_pole[] Longname:rotated_pole Missval:NA" [1] "float t2m[rlon,rlat,height,time] Longname:2-m Temperature Missval:1e+30" I wonder now how to make a spatial subset of just one grid cell ? I just found temporal subset. it would be of great help.
