Who uses NASA Earth science data?
The EOSDIS is pleased to announce a new EOSDIS data user profile series: “Who uses NASA Earth science data?” These features highlight our diverse end-user community worldwide and show you not only how these data are being used for research and applications, but also where these data are being used -- from the plains of West Texas to the Sea of Oman and everywhere in between. You’ll also learn where you can download the data sets in each feature. We’re excited to share our data user’s experiences with you!
Near Real-Time AMSR2 Data Being Released
Near real-time data from the AMSR2 instrument is the newest addition to the LANCE collection of products that provide satellite data generally within three hours of a sensor observation.

Arctic sea ice reaches lowest maximum extent on record
On February 25, 2015 Arctic sea ice likely reached its maximum extent for the year, at 14.54 million square kilometers (5.61 million square miles). This year’s maximum ice extent was the lowest in the satellite record. The image is derived from near-real-time passive microwave data archived at the NSIDC DAAC. The graph shows Arctic sea ice extent as of March 18, 2015, along with daily ice extent data for four previous years. Click to read more.
SEDAC Map of the Week - Global Anthropogenic Biomes, 1900
Global Anthropogenic Biomes, version 2, 1900 describes the anthropogenic transformations within the terrestrial biosphere caused by sustained direct human interaction with ecosystems, including agriculture and urbanization circa 1900. Visit the Socioeconomic Data and Applications Center to compare the changes in biomes from 1700, 1800 and 2000.
A baffling signal in the tropics
The Madden-Julian Oscillation (MJO) signal, a mélange of intense atmospheric convection, air pressure, and wind, is so strong that it can spike rainfall in the South Asian and Australian monsoons and increase the number of violent tornado outbreaks in the United States. Understanding it could improve long-range weather forecasts and enable scientists to further refine computer models of global climate. Click to read more of this Sensing Our Planet article.
