Earthzine has partnered with the NASA Earth Science Technology Office (ESTO) to produce this inaugural “Earth Science Technology Showcase,” an online forum that features 10 current Earth-observing technology development projects.
Indigenous people in Brazil, like original inhabitants of places around the globe, have a rich traditional of charting the night sky and using their celestial awareness in ways that embrace both the spiritual and the pragmatic. Brazilian physicist Germano Bruno Afonso warns that this knowledge is threatened by a modernity that devalues indigenous culture.
Tracking Super Typhoon Haiyan: International Effort Provides New Views of Monster Storm, Saves Lives
An international team of researchers relied on new technologies and a constellation of satellites to track and predict the path and strength of one of the most powerful tropical cyclones in recorded history. Many people died, but many lives also were saved by this unique collaborative effort.
Virtual Poster Session
This fall’s installment of the DEVELOP Virtual Poster Session series features interdisciplinary research projects that apply the lens of NASA Earth observations to community concerns around the globe. In short video format, DEVELOP teams in the U.S., Mexico, and Nepal communicate the capabilities of NASA Earth observations to address diverse environmental and public policy issues. These include monitoring conservation efforts, water quality, rangeland loss and aerosol transport; and mapping the risks of natural disasters like earthquakes and wildfires.
Urban Climate Archipelagos (UCAs) are proposed as a way to frame the emerging aggregations of urban land. As the Earth becomes increasingly “urbanized,” UCAs will likely play an increasing role in the climate system. At the same time, model spatial resolutions are approaching the dimensions to represent adequately ever-expanding urban footprints and UCAs. Herein, we offer a framework for one facet of the urban climate community to consider.
Wildfire Management – Recent Experiences on the Ground and how Remote Observation can add to the Picture
For all the recent progress in Earth Observation technologies, wildfires remain a serious problem that poses ever-increasing challenges to our ingenuity. Minimizing their often-dramatic environmental and human impacts will require a smart combination of technology, political decision, and willingness to accept changes in our own individual and collective options as societies. In order to show how fire hazard is threatening many parts of the world on a recurrent basis, details are provided on the recent severe 2013 fire season in Portugal, along with background information on remote sensing of wildfires and related disaster risk management challenges.
EOMAP and its partners have created a comprehensive digital map of the Great Barrier Reef. This is the first complete, high-resolution digital map to be made of the reef, and project participants hope that it will help to further research and preservation.
The aim of the “Open Geospatial Science & Applications” webinar series is to share experiences and examples of research and teaching on open source geospatial technology to the wider community. The next seminar is planned for Dec. 10. The series is due to continue for at least six months.
With every tweet, Facebook update, or web search, geospatial data are being generated from technological devices underpinned by the Global Navigation Satellite System (GNSS). As access to mobile technology expands across the globe, the amount of user-generated data will expand with it.
“The results from satellite data were stunning.”- Sameh Wahba, manager of Urban Development and Resilience, the World Bank, on the ESA (European Space Agency) partnership using satellites to identify areas in Tunis, Tunisia, at risk for extreme weather events on the Mediterranean coast.
The theme aims to highlight the relevance and value of Earth Observations (EO) --- from satellites, to buoys and land networks --- for health and safety. EO examples include: Visible, IR, and Water Vapor satellites, Dual-pol Radars, and Ground-Station Networks for the atmosphere; and Gliders, Pier Stations, and Water Sampling for the oceans.
Earthzine is soliciting articles of 800-3,000 words for its first quarter 2014 theme on Earth Science Informatics Challenges. This theme focuses on the challenge of performing analysis with voluminous Earth science data products that are becoming increasing difficult to migrate to high-productivity computing platforms.
In a collaboration of NASA’s Jet Propulsion Laboratory and the Hydro and Agro Informatics Institute of Thailand, sensorweb technologies are being used to enhance monitoring of flooding in Thailand. This Thailand Flood Sensorweb utilizes automation techniques to detect flooded areas, alert interested parties, and deliver imagery.
The authors have developed a novel broadband antenna technology that enables remote sensing measurements over the X- to Ka-band microwave spectrum from a single aperture. The antenna technology is integrated with an airborne X- and Ku-band synthetic aperture radar and K-and Ka-band radiometer for measuring the spatial distribution of surface snow.
Analyzing Tropical Waves Using the Parallel Ensemble Empirical Model Decomposition Method: Preliminary Results from Hurricane Sandy
To reveal multiscale processes from high-resolution, multidimensional Earth science data, we have developed the parallel version of the ensemble empirical model decomposition (PEEMD) method with a three-level parallelism. In this study, we illustrate the performance of the PEEMD in extracting tropical wave components from idealized tropical wave solutions and large-scale environmental flows associated with Hurricane Sandy.
This paper describes the first fiber-coupled, distributed-feedback semiconductor lasers operating near 2.051 um wavelength with record high output power. Among the novel applications and instruments they enable are carbon dioxide concentration measurements in air.
Climate models and observations are generated from a variety of sources and by a variety of institutions. The Regional Climate Model Evaluation System provides the necessary software and architecture to easily and rapidly perform model evaluation activities.
Measuring Earth’s Radiation Imbalance with RAVAN: A CubeSat Mission to Measure the Driver of Global Climate Change
RAVAN will demonstrate two key technologies that enable accurate, absolute Earth radiation measurements using a remarkably small instrument: a vertically aligned carbon nanotube forest absorber and a gallium fixed-point blackbody as a calibration transfer standard.
Scientists have discovered huge reserves of freshwater beneath the oceans kilometers out to sea, providing new opportunities to stave off a looming global water crisis. A new study reveals that an estimated half a million cubic kilometers of low-salinity water are buried beneath the seabed on continental shelves around the world.
