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."

Crowdsourcing and Citizen Science data for water resources management

The provision of water resources is one of the most fundamental ecosystem services . An acute scarcity of water data in both, the spatial and temporal domains in many regions prompts the urgency to assess risks related to water such as water quality decline, floods and droughts. Remote sensing does provide us with relevant data for water resources monitoring, but this data still needs to be validated with in-situ observations and measurements.
