Functions for low-level access to numerical data in NetCDF files. They have been optimized for maximum speed and memory efficiency.
netCDFStrError(ncerr) netCDFOpen(filename) netCDFClose(ncid) netCDFVarID(ncid, var) netCDFVarLen(ncid, var) netCDFVarDouble(ncid, var) netCDFVarInt(ncid, var) netCDFMSPoints(ncid, scanIndex)
filename |
path to NetCDF file |
ncid |
NetCDF file ID |
var |
NetCDF variable ID or variable name |
scanIndex |
double vector with scan_index from CDF file |
The mechanisms and structure of NetCDF files are not discussed here, please se the NetCDF documentation for more information.
netCDFStrError returns the textual description of an error code.
netCDFOpen returns the ncid of the opened file.
netCDFClose returns the closing status.
netCDFVarID returns the variable ID.
netCDFVarLen returns the variable length.
netCDFVarDouble and netCDFVarInt return either
double or integer numeric vectors.
netCDFMSPoints returns a list with elements massValues
and intensityValues, with the masses for each scan in
ascending order.
An error in any of the functions will return an integer error
code with attribute errortext containing the error description
