Several ground‐based and airborne data sets taken with the Global Navigation Satellite System Reflectometry (GNSS‐R) technique are made available to the research community. This paper reviews the potential applications of these bistatic radar observations, including a list of possible approaches and algorithms described in the literature for oceanic measurements (altimetric and scatterometric), soil moisture sensing, and sea ice and snow characterization. A list of applicable models complements the review. The paper continues with descriptions of the campaigns included in the initial data set, together with the basic information required to understand the instrumental issues of the data. Finally, some parameters and observables provided in the data are detailed. Key Points A large data set of GNSS‐R observations is made available for research The potentially applicable models, applications, and techniques are reviewed The data content is detailed, together with open issues for research
