Remote sensing of nighttime light emissions offers a unique perspective for investigations into human activity and the impact of natural disasters. Learn about the collection of nighttime lights data, how these data are used, and NASA sources for acquiring these data in the new Nighttime Lights Backgrounder.
A new NASA Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) dataset, “High-Resolution Land Cover-Specific Solar-Induced Fluorescence” provides solar-induced chlorophyll fluorescence (SIF) of specific vegetation types and total SIF under clear-sky and real/cloudy conditions at a resolution of 4 km for the Midwest USA. Discover and access data.
The mountains of Nepal are one of the most hazardous environments in the world, with frequent landslides caused by tectonic activity, extreme rainfall, and infrastructure development. As a landlocked country, Nepal relies on the proper functioning of major transportation networks such as the highways to sustain and improve the livelihoods of the population. Every year there are reports of landslides blocking the highways, especially during the rainy season; however, the frequency and location of landslides along the highway corridors are not well reported. RapidEye satellite imagery was used to create annual landslide initiation point inventories along three important highways in Nepal: the Arniko, Karnali, and Pasang Lhamu highways. These data are available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
Human activities have increased the amount of carbon dioxide in the atmosphere by 47% since the Industrial Revolution began. Find data on carbon dioxide and other climate-warming gases, along with resources for using these data, in the new Greenhouse Gases Data Pathfinder.
