Giovanni Workshop Lets Earth Scientists Share Global Earth Science Data

EarthzineApril 2, 2013Articles, Earth Observation, Original, Sections

A slide from Suhung ShenÛªs presentation, ÛÏExploring land processes and climate variations through Giovanni,Û showing Giovanni-generated rain rate anomaly data and normalized difference vegetation index (NDVI) anomaly data for central Texas, plotted with Microsoft Excel.

The NASA Giovanni system allows researchers to easily find, and rapidly visualize and analyze, a wide variety of Earth observation data. Many scientists around the world have discovered and used the system. An online workshop (named in honor of Dr. Gregory G. Leptoukh, who led the development of the system for several years) was convened to share Giovanni’s contributions to recently-published research in many different disciplines of Earth science.

Key phrase trends in climate change research and communication

EarthzineMarch 23, 2013Articles, Climate, Environmental Awareness Theme, In-Depth, Original, Sections, Themed Articles

Figure showing database search results using CC as the key phrase. The annual counts for research articles and New York Times articles are displayed on the primary axis while annual counts for NSF grants are displayed on the secondary axis. The vertical lines denote years with notable climate change-related events.

Words are important. Using Û÷climate change’ instead of Û÷global warming,’ or vice versa, may not seem that major of a difference. But research shows there is a large gap between usage of the phrases and what is associated with each term.

Climate modeling is a crucial tool that can inform decision-making where billions of dollars — and often public health and safety — are at stake. An expert panel finds significant gaps in U.S. climate modeling infrastructure and outlines a national strategy to help unify climate-modeling efforts and advance the country’s ability to anticipate future change.

Greg Mort, of Maryland, brings an astronomer’s eye to the art of painting. His work often features apples, conch shells, ribbons and lace juxtaposed with images of the universe amidst natural settings seen on Earth.

Mapping the very shallow geothermal potential in Europe and selected case study areas

EarthzineJanuary 24, 2013Articles, Earth Observation, Original, Sections, Technology

Though the world is moving toward alternative and renewable energy sources, little is known about the potential of very shallow geothermal energy sources. The ThermoMap project aims to provide usable data on local geothermal conditions across Europe.

The Institute for Global Environmental Strategies’ annual art contest serves as a prime example of integrating art and science in the classroom. Students benefit from the practice of visually sharing what they know. Instructors are able to tailor their lessons based on the artistic renderings of students.

Urbanization will be one of the big global challenges in the 21st century. However, to date there are no tools to monitor this growth at a global level in a sustainable way. This article proposes a new concept to map and monitor the global human settlements based on high resolution satellite imagery.
