Data Types

Gridded Data (GridDAP)

GridDAP datasets are multidimensional grids with shared dimensions. They typically have time, vertical, north-south, and east-west dimensions, or any combination of these. The horizontal dimensions may either be geographic or arbitrary Cartesian coordinates. All NCEI data currently in the NCEI-NC ERDDAP is grid data.

Table Data (TableDAP)

TableDAP data sets look like a spreadsheet or database table, and can be queried like a database table. ERDDAP makes it possible to access any dataset in this format.
