# read the netCDF file and print its list of variables
nc = read("fc_12.nc")
vars = variables(nc)
print(vars) # we could also do: print(variables(nc))
# set the current variable to be t2m and print its attributes
setcurrent(nc, 't2m')
atts = attributes(nc)

Run the macro and see - this is what it printsshould print:

First, use the values() function to extract arrays of lats, lons and T2m from the CSV data. These will be returned in variables of type vector - this is an in-memory array of double-precision numbers.

vector or list values( table, number ) Returns the given column specified either by an index (starting at 1) or a name (only valid if the table has a header row). If the column type is number, a vector is returned; if it is string, then a list of strings is returned. If the column cannot be found, an error message is generated. |
