I am very new with netcdf file. And currently have to extract the data from such netcdf which looks like below:
8 variables (excluding dimension variables): double time_bnds[bnds,time] int rotated_latitude_longitude grid_mapping_name: rotated_latitude_longitude grid_north_pole_latitude: 39.25 grid_north_pole_longitude: -162 north_pole_grid_longitude: 0 float lat[rlon,rlat] standard_name: latitude long_name: latitude coordinate units: degrees_north bounds: lat_vertices float lon[rlon,rlat] standard_name: longitude long_name: longitude coordinate units: degrees_east bounds: lon_vertices float lat_vertices[vertices,rlon,rlat] units: degrees_north float lon_vertices[vertices,rlon,rlat] units: degrees_east double height units: m axis: Z positive: up long_name: height standard_name: height float tasmax[rlon,rlat,time] standard_name: air_temperature long_name: Daily Maximum Near-Surface Air Temperature comment: daily-maximum near-surface (usually, 2 meter) air temperature. units: K cell_methods: time: maximum history: 2015-05-06T15:11:26Z altered by CMOR: Treated scalar dimension: 'height'. 2015-05-06T15:11:26Z altered by CMOR: replaced missing value flag (-1e+20) with standard missing value (1e+20). coordinates: height lat lon missing_value: 1.00000002004088e+20 _FillValue: 1.00000002004088e+20 associated_files: gridspecFile: gridspec_atmos_fx_MPI-CSC-REMO2009_rcp45_r0i0p0.nc grid_mapping: rotated_latitude_longitude 5 dimensions: time Size:1825 *** is unlimited *** bounds: time_bnds units: days since 1949-12-01T00:00:00Z calendar: proleptic_gregorian axis: T long_name: time standard_name: time rlat Size:103 units: degrees axis: Y long_name: latitude in rotated pole grid standard_name: grid_latitude rlon Size:106 units: degrees axis: X long_name: longitude in rotated pole grid standard_name: grid_longitude bnds Size:2 vertices Size:4
Although, there are many explanation of different netcdf files but I found my situation is a bit complicated in terms of number of variables and dimensions. Here I am confused with float lat[rlon,rlat]; why rlon and rlat is here with normal latitude? Similarly with the case of float lon[rlon,rlat]. And why rlon and rlat separately present in dimensions also?
Eventually I need to extract the temperature with geographical coordinates (latitude North and longitude East).
