Citizen Science for Earth Observations

"Citizen science, is described as the method that involves citizens or communities in the scientific research process, has been used in a wide range of studies since the term was first introduced in the 1980s. In the era of big data, citizen science is increasingly attracting attention across a wide variety of scientific disciplines, as indicated by the appearance of vast reports, projects, and peer-reviewed publications. It significantly expands data collection means and scope across temporal and spatial scales, especially in urban hydrologic research. With the fast development and exponential adoption of low-cost sensors, citizen science, especially crowdsourcing, provides a promising direction to (at least partially) address the data challenge."
