MODIS and Vector-Borne Diseases

Remote sensing via satellites enables us to survey the spatial-temporal patterns of vector-borne diseases in both near and distant places. In this article, MODIS imaging time series, in particular, are explored as an application to bolster surveillance and vector control programs.

NASA Earth Exchange (NEX): Managing Scientific Knowledge and Collaboration

NASA Earth Exchange (NEX) is a collaborative platform that combines state-of-the-art supercomputing, Earth system modeling, remote-sensing data from NASA and other agencies, and a scientific social network to provide an environment in which users can explore and analyze large Earth science data sets, run modeling and analysis codes, collaborate on new or existing projects, and share results within or among communities. A number of technologies are being tested to enhance scientific productivity within the NEX community.

Historic Release of Water Aims to Restore a Once-Lush Landscape in the Colorado River Delta

In a concerted effort to remediate the ecosystems along the channel of the Colorado River, Mexico and the United States recently reached a historic agreement to release water from the Morelos Dam at the Arizona-Mexico border. This ‘pulse flow,’ is intended to reach the Colorado River Delta for the first time in 50 years.

Greening Hamburg: A Model for Sustainability

Earth Day 2014 is upon us, and the theme for the year is Green Cities. The theme was selected by the Earth Day Network in recognition of the fact that more people now live in urban than rural areas and that the challenges of achieving a desirable quality of life in the face of growing populations will be compounded by the effects of climate change.

Earth Science Data Analysis in the Era of Big Data

Many Earth scientists are wondering: How will Big Data technologies benefit Earth science research? To illustrate the effects of combining a Big Data technology with an effective means of collaboration, we relate the (fictitious) experience of an early-career Earth science researcher a few years beyond the present, interlaced and contrasted with reminiscences of its recent past.

Improving Numerical Weather Prediction Models and Data-Access Latencies

The data center community must work to allow researchers more time to spend on analyzing results and less time coding and worrying about file formats and data transfers. We identify some of the existing limitations of traditional archives, discuss examples of model data diagnostics, and explore the many benefits of providing archive-based computational resources on peta-scale databases.

Twenty Buses a Day: The High Stakes Race to Create a Global Cholera Early Warning System

What infectious disease kills the most children under the age of five? If you guessed malaria or AIDS, guess again. Cholera claims more victims than either of those diseases. Now, a team of researchers are developing a method to provide early warning of cholera outbreaks. If successful, the effort could drastically reduce the number of cholera deaths.

OGC netCDF: Powerful Tool for Science

A widely used "fluid earth systems" data model and data access standard called netCDF now provides an important bridge between GIS and the complex 4-D processing systems used in oceanography and atmospheric sciences. By bringing netCDF into the Open Geospatial Consortium (OGC) standards organization, the netCDF community has given climate scientists, for example, a streamlined method for bringing virtually all types of spatial/temporal data and processing into climate science models and workflows.

Opposition had been building from real estate agents, from home builders planning subdivisions, and then from politicians. When all that energy was released, the science was crushed flat.

Arctic Melting is Lasting Longer and Affecting More Ice: Study

Originally Published by Universe Today - The Arctic melt season is averaging five days longer with each passing decade, a new study by NASA and the National Snow and Ice Data Center reveals. And with more ice-free days, the water (which is darker than the surrounding ice) is absorbing the sun’s heat and accelerating the process. This means the Arctic ice cap has shrank by as much as four feet.
