Gridded data works well for satellite images, model data, and data compilations such as the Reynolds data we've just looked at. Other data, such as data measured at a specific site, is not so readily stored in that form. OPeNDAP provides a data type called a Sequence to store this kind of data.
A Sequence can be thought of as a relational data table, with each column
representing a different data value, and each row representing a different data
"instance." For example, an ocean {temperature profile} can be stored as a
Sequence of pressure and temperature pairs, and a weather station's data can be
stored as a Sequence with time in one column, and each weather variable
occupying another column.
Let's look at a set of two Sequences. The first gives the locations of a set of inverted echo sounders, and the second gives their observations over time. The data is here:
