The Commercial UAV Expo published a free report, UAVs in Precision Agriculture, which describes how drone/UAS/UAV technology is reshaping how farmers and growers perform crop scouting, nutrient management, field mapping, drainage assessment and more.
NASA's Oceans Melting Greenland (OMG) field campaign is gathering data that will help scientists understand how the oceans are joining with the atmosphere to melt the vast ice sheet as well as predict the extent and timing of the resulting sea-level rise.
An article in the New York Times Magazine chronicles how data analysts, the government of Palau and a nonprofit organization called SkyTruth are using satellite data to fight fishing poachers in the nation made up of 250 separate islands.
A team of Nevada scientists and unmanned aircraft system (UAS) engineers successfully flight tested the first-ever autonomous cloud-seeding aircraft platform.
The European Alps stretch 1,200 kilometers (750 miles) across eight countries, and it's the longest mountain chain situated entirely within Europe. The Alps include more than 100 peaks higher than 4,000 meters (13,000 feet), and this image from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) on its Terra satellite beautifully captures a recent snowfall across the region.
A new study by NASA and several partners found that in California's Sierra Nevada, atmospheric river storms are two-and-a-half times more likely than other types of winter storms to result in destructive rain-on-snow events, where rain falls on existing snowpack, causing it to melt.
The Group on Earth Observations (GEO) introduced the Early Warning Crop Monitor (EWCM), a new tool that provides consensus reports on crop conditions in countries at risk of food insecurity in Central and South America, Africa, the Middle East, and Central and East Asia.
Students participating in NASA's EarthKAM program can request photographs of specific Earth features, such as this image of South Africa, which are taken by a special camera mounted on the International Space Station when it passes over those features.
Carbon tetrachloride (CCl4), once commonly used as a cleaning agent, is a known air toxin that eats away at the ozone layer. Its production has been banned for many years, but a new CIRES and NOAA study reports those rates are still 30-100 times higher than amounts reported to emission inventories.
Using data from the NASA/USGS Landsat 8 satellite, researchers have detected sediment plumes extending as far as four kilometers downstream from shallow shipwreck sites, demonstrating how satellites may be used to locate the watery graves of coastal shipwrecks.
