|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 file for dataset of this size. This file will be approximately 20499904 bytes, with 4 columns of 1281244 numbers.|
|2-Dimensional Tab-Separated Tables||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.|
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 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 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 X
are separated by tabs and data values corresponding to different
Y 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.
|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.|
