NASA’s Applied Remote Sensing Training Program (ARSET) has opened a new open, online introductory webinar series: Connecting Citizen Science with Remote Sensing. This 3-part training, delivered in English and Spanish, will provide attendees an overview of citizen science efforts that use Earth Observations combined with ground-based information in the fields of climate change, sustainable development, ecosystem monitoring and characterization, drought, and land cover or land-use change, and will highlight case-study examples of successful citizen science projects, with some examples from NASA supported projects and activities. This training will provide attendees an overview of citizen science efforts that use Earth Observations, and how to engage with community members in a supportive and meaningful manner to achieve project goals. Attendees will also be provided with case-study examples of successful citizen science projects, with some examples from NASA supported projects and activities. We will highlight projects like NeMO-Net, a global coral reef classification with 2D and 3D images application combined with machine learning; Floating Forests, a Giant Kelp monitoring platform where participants can classify kelp in Landsat images; Snapshot Wisconsin, a project that uses images of wildlife from trail cameras to assist with habitat mapping; and Soundscapes to Landscapes, where bird diversity in California is monitored by identifying specific species through sound recordings. We will also highlight the Global Learning and Observations to Benefit the Environment (GLOBE) Program, an international science and education program, and GLOBE Observer, a citizen science app that allows volunteers in GLOBE countries to take observations and contribute to the community.
