IRI Analyses ENSO-RP ver1950-2002 2p5deg prob Data Files

This dataset has bytes (2985984 2.8476562MB) 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 is an inefficient format, so you would have gotten a HUGE file for dataset of this size. This file will be approximately 17915904 bytes, with 6 columns of 746496 numbers.

ENSO T Table
Tab-separated-values (tsv) file with information about the independent variables (i.e., grids). The list to the left allows you to specify the format of the table. Note: The variable running across the top of the table (identifing columns) is listed first and the variable running down the side of the table (identifing rows) is listed second.
GIS-Compatible Formats
There are three GIS-compatible formats available.
2-Dimensional Table A 2-dimensional ascii file that includes an ArcInfo Header.
IDA Image File(s) in the Image Display and Analysis format. Typically used with WinDisp.
LAN Image File(s) in the ERDAS LAN format. Typically used with various GIS programs, including ArcView and HealthMapper.
GeoTIFF Image File in GeoTIFF format. Typically used with various GIS programs, including ArcView and ENVI.

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 X Y prcp ENSO 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 all the X Y points. It must be read using FORTRAN sequential access. Records correspond to prcp ENSO T, with the first grid varying the fastest.
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 X are separated by tabs and data values corresponding to different Y prcp ENSO T 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: X Y prcp ENSO T | X Y X prcp X ENSO X T Y prcp Y ENSO Y T prcp ENSO prcp T ENSO T | X Y prcp X Y ENSO X Y T X prcp ENSO X prcp T X ENSO T Y prcp ENSO Y prcp T Y ENSO T prcp ENSO T | X Y prcp ENSO X Y prcp T X Y ENSO T X prcp ENSO T Y prcp ENSO T | X Y prcp ENSO T |

Text Text file where data is arranged in chunks of X Y. 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.
