What does Large File Support have to do with netCDF? When the netCDF format was created in 1988, 4-byte fields were reserved for file offsets, specifying where the data for each variable started relative to the beginning of the file or the start of a record boundary.

The netcdf file libsrc/posixio.c is used as the OPeNDAP file nc3-dods/lnetcdf/posixio.c with very few changes. The assertion that fails above is the same in both versions of the file and none of the other changes jump out at me as being likely to affect this assertion.

Assuming the underlying file system has support for large files, the total size can exceed 2 GB, but there are severe restrictions regarding the number of large variables and the order in which they are written.

NETCDF Large File Support now default (#112) TYPE: enhancement KEYWORDS: NETCDF, WRFIO_NCD_LARGE_FILE_SUPPORT SOURCE: internal DESCRIPTION OF CHANGES: The default behavior in WRF now assumes that the user will use LARGE FILE SUPPORT. If a user wishes to disable this capability, then the user sets the env variable WRFIO_NCD_NO_LARGE_FILE_SUPPORT.

A Note About Large File Support. The classic CDF file format (referred as CDF-1) has been solely in use by NetCDF library through version 3.5.1. The classic format has been updated by NASA ESDS community standard and added a support for 64-bit offset file format (also referred as CDF-2). See NetCDF Classic and 64-bit Offset File Formats.

I should have read the Unidata NetCDF large file support more carefully. Changing to NetCDF4 solved the problem. Cheers, Klemens Dominikus Heinzeller schrieb: > Hi Klemens, > > I am not entirely sure, but: The classical netCDF file format imposes > a limit of 4GB on individual variables.

I have a 17G netcdf file that I am trying to use for analysis. Each variable in the netcdf file is set up like: variable(x,y,z,time). I would like to read in and analyze the variables one 'time' at a time for analysis in Matlab. In other words, I want to use all x, y, and z points at one time.

"NetCDF (network Common Data Form) is a set of interfaces for array-oriented data access and a freely-distributed collection of data access libraries for C, Fortran, C++, Java, and other languages. The netCDF libraries support a machine-independent format for representing scientific data.Developed by: UCAR
