This has led to longer growing seasons for plants at high latitudes and changes to the soils. To determine how vegetation across Alaska and Canada is responding to these conditions, scientists analyzed 29 years’ worth of measurements from USGS-NASA Landsat satellites. The satellites can identify the amount of healthy plants on the ground by detecting visible and near-infrared light reflected by the green, leafy vegetation of grasses, shrubs and trees. Scientists found that 30 percent of the landscape had an increase in vegetation between 1984 and 2012, while 3 percent showed a decline. The findings will help scientists investigate what other environmental factors might impact plant growth in the Arctic.

There are two instruments on the spacecraft, the Thermal InfraRed Sensor (TIRS) and the Operational Land Imager (OLI). Landsat 8 continues the nearly 50-year long Landsat land imaging data set. In addition to widespread routine use for land use planning and monitoring on regional to local scales, support of disaster response and evaluations, and water use monitoring, Landsat 8 measurements directly serve NASA research in the focus areas of climate, carbon cycle, ecosystems, water cycle, biogeochemistry, and Earth surface/interior. || ", "release_date": "2011-10-05T15:00:00-04:00", "update_date": "2023-05-03T13:53:35.932815-04:00", "main_image": { "id": 482976, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a010800/a010812/LDCM_still_Gulf_Coast_front_view_2000x1126.jpg", "filename": "LDCM_still_Gulf_Coast_front_view_2000x1126.jpg", "media_type": "Image", "alt_text": "An artist's conception of the Landsat Data Continuity Mission (LDCM), the eigth satellite in the long-running Landsat program, flying over the US Gulf Coast.", "width": 2000, "height": 1126, "pixels": 2252000 } } ], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
