Indices nino NCEP_OIv2 NINO4 Data Files

This dataset has bytes (3456 0.003295898MB) of data in it, which should give you a rough idea of the size of any file that you ask for.

Other Available File Formats

Full Information Formats
These files contain all of the available metadata.
OPeNDAP A system which downloads data directly to software, such as matlab, Ferret, GrADS, etc. Specific instructions are available in the table above. Note: OPeNDAP was formerly known as DODS (Distributed Oceanographic Data System). More Information
netCDF (network Common Data Form) A commonly supported self-describing data format. More Information


Partial Information Formats
These files contain only some of the available metadata.
Columnar Table A table with separate columns of numbers for each independent variable (i.e., grids) and for the data. This columnar table is available in a variety of file and column formats here. Note: By setting the helper for mime-type text/tab-separated-values, you can have this loaded directly into your favorite spreadsheet. There are 2 columns of 432 numbers.
Data Only Formats
These files contain just the data without any of the available metadata.
Binary direct access A big-endian, ieee single-precision file in floating-point format. Also known as a binary random access file. This is a random-access file; it is purely data with no record-structuring information. The data is structured to correspond to the independent variables (i.e., grids) in T order, with the first grid varying the fastest.
DEC ALPHA direct access Same as the binary random/direct access format above except that it is byte-swapped for DEC ALPHA's and PC's (little-endian).
Binary FORTRAN sequential access A big-endian, ieee, single-precision file in floating-point format. This is a sequential-access file with each record containing one point. It must be read using FORTRAN sequential access. Records correspond to T.
DEC ALPHA sequential access Same as the binary sequential access format above except that it is byte-swapped for DEC ALPHA's and PC's (little-endian).
Text with tab-separated-values Text file where data values corresponding to different T are separated by tabs and data values corresponding to different are on different lines. This is readable by most programs, including spreadsheets, but will be about four times larger than the binary or netCDF/HDF files noted above.

As an alternative, you can access a tab-separated file with the following independent variables (i.e., grids) grouped on each line: T |

Text Text file where data is arranged in chunks of . There are five values per line and each chunk starts on a new line. This will be about four times larger than the binary or netCDF/HDF files.
