netcdf

问题 Let's assume I have 2 netCDF data files with data for the same region (like South America, Africa, etc) but the different grid sizes as 0.5 degrees x 0.5 degrees and 1.0 degrees x 1.0 degrees in another. I want to increase or decrease its grid size to a different value such as 0.25 x 0.25 or 1.0 x 1.0 so that I can use this easily for raster calculations and comparison, etc. Is there a method to do this using any bash script, CDO, etc. A sample data can be downloaded from here. https://www

问题 I have a NetCDF file which include lots of variables (1d, 2d, 3d, and 4d). I want to add a new dimension to one of the 3d variables. To make it more clear, suppose: I have a 3d variable: A(d1, d2, d3) I want to have 4d variable: A(d1, d2, d3, d4) In fact, d4 is the new dimension which I would like to add to my variable. I do not have d4 in my file. I know it has just one value. I would appreciate that if anyone guide me. 回答1: Using NCO: ncap2 -s 'defdim("d4",737);A_new[$d1,$d2,$d3,$d4]=A' in

问题 I'm trying to include/link the NetCDF C library (https://www.unidata.ucar.edu/software/netcdf/docs/index.html) into my C++/CUDA project with cmake. I seem to be running into issues, though. I am on Windows 10 and have installed the NetCDF C libraries for Windows, version 4.7. Including the NetCDF libraries seems to go without a hitch, the problem is in the linking step. My code that uses the NetCDF library: netcdf_writer.cpp #ifndef __CUDACC__ //only actually include the NetCDF libraries if

问题 I want to add a new variable to an existing netcdf file which simply increases linearly with the time variable of file, that is to say, on the first time slice the variable has the number 1 everywhere, on the second timeslice it is set to 2, etc. I know how to open the file in python or fortran and define and add the variable and write out the modified file, but I was hoping that there might be a quick and easy way to do this from the command line using nco . I also wondered if I could do it

问题 I have a netCDF file with the foll. ncdump: netcdf nc_data { dimensions: lon = 1440 ; bounds = 2 ; lat = 720 ; time = UNLIMITED ; // (6 currently) variables: double lon_bounds(lon, bounds) ; double lat_bounds(lat, bounds) ; int time(time) ; time:units = "year as %Y.%f" ; time:calendar = "proleptic_gregorian" ; time:long_name = "time" ; time:standard_name = "time" ; time:axis = "T" ; float lat(lat) ; lat:units = "degrees_north" ; lat:long_name = "latitude" ; lat:standard_name = "latitude" ;
