NASA's Soil Moisture Active Passive (SMAP) instrument to be launched this month
Scheduled for launch on 29 January 2015, NASA's Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth's soils with an unprecedented accuracy and resolution. The instrument's three main parts are a radar, a radiometer and the largest rotating mesh antenna ever deployed in space.
Remote sensing instruments are called “active” when they emit their own signals and “passive” when they record signals that already exist. The mission's science instrument ropes together a sensor of each type to corral the highest-resolution, most accurate measurements ever made of soil moisture -- a tiny fraction of Earth's water that has a disproportionately large effect on weather and agriculture.
To enable the mission to meet its accuracy needs while covering the globe every three days or less, SMAP engineers at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, designed and built the largest rotating antenna that could be stowed into a space of only one foot by four feet (30 by 120cm) for launch. The dish is 19.7 feet (6 metres) in diameter.
SMAP's radar, developed and built at JPL, uses the antenna to transmit microwaves toward Earth and receive the signals that bounce back, called backscatter. The microwaves penetrate a few inches or more into the soil before they rebound. Changes in the electrical properties of the returning microwaves indicate changes in soil moisture, and also tell whether or not the soil is frozen. Using a complex technique called synthetic aperture radar processing, the radar can produce ultra-sharp images with a resolution of about half a mile to a mile and a half (one to three kilometres).
SMAP's radiometer detects differences in Earth's natural emissions of microwaves that are caused by water in soil. To address a problem that has seriously hampered earlier missions using this kind of instrument to study soil moisture, the radiometer designers at NASA's Goddard Space Flight Center, Greenbelt, Maryland, developed and built one of the most sophisticated signal-processing systems ever created for such a scientific instrument.
The problem is radio frequency interference. The microwave wavelengths that SMAP uses are officially reserved for scientific use, but signals at nearby wavelengths that are used for air traffic control, cell phones and other purposes spill over into SMAP's wavelengths unpredictably. Conventional signal processing averages data over a long time period, which means that even a short burst of interference skews the record for that whole period. The Goddard engineers devised a new way to delete only the small segments of actual interference, leaving much more of the observations untouched.
Combining the radar and radiometer signals allows scientists to take advantage of the strengths of both technologies while working around their weaknesses.Date January 6, 2015

Jisc's call for research data management ideas (Research Data Spring)
As part of their effort to create new solutions to common research problems, Jisc are looking for ideas from individuals and groups with an interest in research data. Please submit your ideas to promote solutions, and offer fresh perspectives for facilitating research data management. Everyone is also invited to vote for their favourite idea, or against other ideas! A simple registration is required in order to participate.
In particular, Research Data Spring is interested in ideas that make it easier to manage research data, especially from the researchers’ perspective (in addition to protocols mentioned within the first theme); in this context, it includes the re-use of data. In other words, Research Data Spring is seeking ideas that will smooth the processes of data management, deposit and re-use within the research lifecycle. This area is closely related with “data creation, deposit and re-use”, but the two are split in order to emphasize that some ideas might be focusing on generic data management support and related protocols and solutions for deposit and re-use, while others would address key disciplinary and cross-disciplinary research aspects.
As of today, the following 25 ideas have been submitted for voters' considerations:
- Streamlining Deposit: An OJS to Repository Plugin
- Badges as a proxy for peer review of data
- Standards and Schemas for Digital Research Notebooks
- The Lab Box: Solve local backup, work towards rich metadata
- Exchanging experience on RDM integration and interoperability
- Research Data Infrastructure for the Visual Arts (RDIVA)
- Provenance and Packaging
- Standard protocol for research equipment
- A metadata standard to enable automated genealogy generation
- Mock idea: note that title is limited to 68 characters
- Integrated RDM toolkit/service
- Data browsing tools for repositories
- Collaboration tool for qualitative data analysis
- One page micro repositories
- Symplectic for RDM purposes
- DAF Question Bank
- BOOKISH: Infrastructure Sharing for the NLS
- Workshops/Training on Stakeholder Support of Researchers
- Data retrieval via persistent identifiers (DOIs)
- Exporting from DMPonline to data journals
- Linked data notebook
- Use semantic desktop to capture contextual research data
- Streamline repository submissions from Zotero profiles
- Research Data requirements vocabulary
- Cloud Work Bench
The one idea submitted that is relevant to the geo-community comes from EDINA at the University of Edinburgh, and below is a summary of the proposal. If you find it an idea worth supporting, please visit the Research Data Spring website and cast your vote.
Cloud Work Bench
The concept of Cloud Work Bench (CWB) is quite simple – to provide researchers in the geospatial domain (GI Scientists, geomaticians, GIS experts, spatial disciplines) the tools, storage and data persistence they require to conduct research without the need to manage the same in a local context that can be fraught with socio-technical barriers that impede the actual research. By streamlining the availability and deployment of open source software tools, by supporting auto-generated web services and using open data, the work bench concept is geared towards removing the barriers that are inherent in geospatial research workflows – how to deploy the tools you want and have the storage and data management capabilities without the overhead of doing it all yourself. Think of it as an academic Dropbox with additional geospatial software tools and data thrown in...
We propose piloting the CWB approach within the geospatial research community which has a well established and broad user base across academia and industry (reflected for example via the uptake of Jisc's flagship Digimap service), and also has a mature open source toolset and data stack which are prerequisites to conducting research e.g. Open Street Map, Ordnance Survey Open data, Postgis, Geoserver, GDAL/OGR.
We anticipate that the CWB concept will be transferable to other domain and disciplinary contexts e.g. statistics.Date December 19, 2014 More information
Clark Labs announces the release of TerrSet
TerrSet is an integrated constellation of software applications for monitoring and modeling the Earth system. Developed in close cooperation with leading institutions focused on sustainable development and environmental conservation, TerrSet provides groundbreaking tools for addressing major challenges to smart growth - climate change: trends, projections and adaptation; land cover conversion: trajectories and impacts; ecosystem services: present and future value. TerrSet = Space + Time Built upon three decades of leadership in the development of GIS and image processing tools (IDRISI), which includes its last release of Selva, Clark Labs has added the critical element of time to create what can now be called a GeoTemporal System (GTS). TerrSet = One System The relationship between TerrSet and IDRISI is thus quite intimate. IDRISI provides two of the major components of the system (GIS Analysis and Image Processing) as well as the foundation for all of the vertical applications. All components use the IDRISI API and the IDRISI data file structures. While IDRISI was once a standalone product, it is now incorporated within the TerrSet software system. TerrSet includes: * Land Change Modeler * GeOSIRIS * Habitat and Biodiversity Modeler * Ecosystem Services Modeler * Earth Trends Modeler * Climate Change Adaptation Modeler * IDRISI GIS Analysis * IDRISI Image Processing Pre-order TerrSet now as shipping is scheduled for 15 January 2015. Trial requests for TerrSet will be available after 20 January 2015.Date December 18, 2014
The Environment Agency: now sharing its flooding data for free
As part of its commitment, the Environment Agency (EA) has announced that as of 11 December 2014, the EA has made its Risk of Flooding from Rivers and Sea datasets easily accessible and available as open data, free of charge and with minimal restrictions. The EA saw the potential for innovation during the flood events last winter when its flood data was released free of charge. Developers came up with a range of solutions to help, from a phone service that connects people with their energy supplier in the event of a power cut, to an app that alerts Twitter users to volunteering opportunities in their local area. The EA hopes that removing cost barriers to their data through Open Data will create more opportunities for developers to create web and mobile applications for businesses and the public to help local communities understand their local environment and better protect themselves from flood risk.Date December 17, 2014
