Real World: Food Security – Monitoring Crops from Space (Video)
Discover how NASA’s Earth-observing satellites gather data to monitor food growth. Dr. Inbal Becker-Reshef describes how mathematics is used to interpret satellite data and describe vegetation and crop yield. Dr. Hannah Kerner shares how algorithms and models use NASA data to describe and predict food supply and food shortages. This work through NASA Harvest provides…

Video: What Does Your Sky Look Like? Globe Observer- Clouds
Clouds are a major component of the Earth’s system that reflect, absorb, and scatter sunlight and infrared emissions from Earth. This affects how energy passes through the atmosphere. Different types of clouds have different effects, and the amount of cloud cover is also important. Clouds can change rapidly, so frequent observations are useful to track…

Video: Icarus Initiative: Wildlife Observation from Space
“Martin Wikelski and his team at the Max Planck Institute for Ornithology are investigating the global migration of animals – initially focusing on small animals such as birds, bats and flying foxes. Tiny transmitters weighing less than five grams, attached to the animals, collect information about their migratory behaviour and transmit it to the ISS.…

PDF: Biodiversity from Space
Mapping and quantifying biodiversity is key to effective conservation planning, yet gathering the necessary data can be costly and time-consuming. Conservationists and land managers therefore place a premium on methods, such as remote sensing, that yield tolerable estimates of biodiversity in the absence of exhaustive ground surveys. Bawa et al. have tested a method of estimating…

Citizen Science: GLOBE Observer- Clouds
“GLOBE Observer: Clouds is an app-based tool that will help you document what you see in the sky. Once you have downloaded the app and created an account, the Clouds tool (including the Clouds Wizard if you wish to use it) will guide you through the observation process. Required data includes providing your location, reporting…

Citizen Science Game: NASA’s Nemo-Net
“NeMO-Net is a single player iPad game where players help NASA classify coral reefs by painting 3D and 2D images of coral…Data from the NeMO-Net game is fed to NASA NeMO-Net, the first neural multi-modal observation and training network for global coral reef assessment. NeMO-Net is an open source deep convolutional neural network (CNN)…

Article: What is Remote Sensing?
“Remote sensing is the acquiring of information from a distance. NASA observes the Earth and other planetary bodies via remote sensors on satellites and aircraft that detect and record reflected or emitted energy. Remote sensors, which provide a global perspective and a wealth of data about Earth systems, enable data-informed decision making based on the…

Article: NASA Fosters Innovative Ways to Understand Biodiversity
“To study and monitor changes in Earth’s biodiversity, or the immense volume of organisms in the world, scientists and citizen scientists record their sightings in the field. At the same time, sensors on the ground and on board satellites and aircraft monitor flora and fauna on a regional to global scale. NASA has funded four…
