The GrADS-DODS Server

What is the GrADS-DODS Server?
The GrADS-DODS Server (GDS) is a stable, secure data server that provides subsetting and analysis services across the internet. These services can be provided for any GrADS-readable dataset. The subsetting capability allows users to retrieve a specified temporal and/or spatial subdomain from a large dataset, eliminating the need to download everything simply to access a small relevant portion of a dataset. The analysis capability allows users to retrieve the results of an operation applied to one or more datasets on the server. Examples of analysis operations include basic math functions, averages, smoothing, differencing, correlation, and regression. The GDS supports operations that can be expressed in a single GrADS expression.

What is DODS?
DODS (Distributed Oceanographic Data System) is a software framework used for data networking. DODS provides tools for making local data accessible to remote locations regardless of local storage format. See the DODS home page for more information.
