What is the GrADS data server?
The GrADS Data Server (GDS, formerly known as the GrADS-DODS Server) is a stable, secure data server that provides subsetting and analysis services across the Internet. The core of the GDS is OPeNDAP, a software framework used for data networking which makes local data accessible to remote locations. GDS 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 GDS 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 any operation that can be expressed in a single GrADS expression.
