Data sets are a necessary part of describing the global water and energy cycle, and provide scientists with the information they need in their work to understand and predict climate variation. GEWEX Panels coordinate the production of data sets from measurements taken from satellites and in situ observation networks around the globe. Links to data sets or the projects that generated them are below.
For an overview on how to assess the quality of a data set, see the Data Set Quality Assessments guide. This aide gives the hows and whys of evaluating how good a data set really is.
