Finding information on local air quality may soon be as easy as a walk in the park. The Environmental Protection Agency announced five cities will be getting Village Green solar-powered air monitoring stations to install in parks and community centers.
The stations use air sensors, miniaturized and low-power computer technology, solar panels and recycled materials to measure common air pollutants and weather conditions. The data is wirelessly transmitted from the stations by cellular modem, quality-checked and then posted online.
The new project aims to increase citizen participation and understanding of local air quality. “The project puts science into the hands of citizens, allowing them to access local air quality information from the benches through on-site displays and a mobile-friendly website,” EPA said.
The real-time data measured by the stations can be used by citizen scientists, students, community organizations and researchers to understand air quality and how events such as weather changes or nearby sources of air pollution can change local conditions. “These new solar-powered, air monitoring park benches provide minute-by-minute data that can help citizens better understand air quality,” EPA Administrator Gina McCarthy said.
The five new monitoring stations will be installed at:
- Independence National Historical Park in Philadelphia;
- The children’s area at the National Zoo in Washington, D.C.;
- The Children’s Garden of the Myriad Botanical Gardens in Oklahoma City;
- Outside the new Kansas City South Branch Library; and
- Outside the Connecticut Science Center in Harford.
A pilot station at South Regional Library in Durham County, N.C., has been operating since June 2013, providing reliable readings every minute on particulate matter, ozone, wind speed and direction, temperature and humidity. The data is automatically streamed to the Village Green Project web page.
The Durham station has been a gathering place for the local community to learn about air quality and has allowed agency researchers to assess how the technology performed, the EPA said. Additionally, the agency is developing a detailed design package for use by anyone who is interested in building a station.

For four days in mid-April, teams from service academies in the United States and Canada competed in the 15th annual Cyber Defense Exercise – a contest in which cadets design and build computer networks and then and defend them against intrusions by the National Security Agency and Canada's Central Security Services. When the April 13-17 exercise was complete, the U.S. Naval Academy emerged as the winner, capturing its third trophy since the contest began in 2001.
The other teams hailed from the U.S. Air Force Academy, U.S. Coast Guard Academy, U.S. Merchant Marine Academy, U.S. Military Academy and the Royal Military College of Canada. NSA's Information Assurance Directorate sponsored the event, which was hosted by the Parsons Group, a technology engineering services firm.
The exercise ran on a virtual private network to prevent any interference with real, working networks. Cybersecurity specialists graded teams’ ability to “effectively maintain network services while detecting, responding to and recovering from network security intrusions or compromises.”
"CDX is a competition singular in its scope, its execution and in training opportunities," the NSA's Alex Gates said in an announcement of the Naval Academy's win. The students "are able to put theory into practice. CDX provides insights and awareness that simply can't be obtained from traditional classroom instruction."

When the General Services Administration's 18F unveiled the Analytics.USA.gov dashboard for federal website traffic, it also posted the code on GitHub. Now the Philadelphia city government has put that open-source project to use for its own sites with analytics.phila.gov.
In an April 20 blog post announcing the launch, City of Philadelphia Data Scientist Lauren Ancona called the new site a "first attempt to capture a 'big picture' website report card in Philadelphia, and it’s still a rough draft. There are currently almost 30 offices or agencies included in the reporting, with around 25 still to add, as well as several non-phila.gov domains."
The dashboard relies on Google analytics, and is a static website that, for the federal-government version, lives in Amazon S3 cloud storage and is served up via Amazon Cloudfront. 18F published an explanation of the project's technical underpinnings in March.

The Army is making plans for a cloud-based fully immersive training environment that aims to make soldiers’ time in the field more productive and meaningful.
"The next capability will be a leader-focused, soldier-centric capability that immerses a soldier, wherever they are at the point of training, in a synthetic environment, that allows us to tailor that environment to the demands of the leader," Col. David S. Cannon of the Combined Arms Center said. Officials expect those next-gen tools to be introduced between 2023 and 2031, Defense Systems reported.
Cannon envisions the use of 3D goggles that that will realistically and cost-effectively replicate real-life scenarios, such as assembling and disassembling weapons systems for soldiers, no matter their location. The virtual training will be a “cloud-based, network-delivered, device-oriented capability that is borne on the mission command information network," he said.
The military as a whole has embraced virtual training tools as a means of more efficient training. The Army’s Future Holistic Training Environment-Live Synthetic, or “Live Synth” encompasses several realistic battlespace scenarios and computer modeled simulations that include training with small arms, armored vehicle and aircraft. The Office of Navy Research’s video game-based training tool Strike Group Defender allows sailors to train in a risk-free environment, offering feedback on performance in deploying electronic mechanisms to either avoid incoming missiles or offensively shoot them down.

The U.S. Geological Survey, through the National Geospatial Program, announced that more than 18 million US Topo quadrangles and Historic Topographic Maps have been downloaded in the past six years from the USGS Store or The National Map Viewer.
In late 2009, the USGS began releasing electronic topographic maps, called US Topo maps. In 2012, the National Geospatial Program added high-resolution scans featuring more than 178,000 historical topographic maps of the United States, known as the Historical Topographic Map Collection (HTMC). Both of these digital products are accessible free of charge.
The HTMC database features high-resolution digital scans of legacy paper USGS maps, some as old as 1884. The most popular HTMC map is the Half Dome, Calif., quadrangle, which has been downloaded 4,257 times. The most viewed and downloaded US Topo map is the Washington West, DC, quadrangle, having been downloaded 2,785 times, according to USGS.
On average nearly 280,000 US Topo and HTMC maps are downloaded each month. That adds up to more than 9,300 downloads per day or nearly 400 every hour. The majority of downloads are downloaded to .net or .com domains, USGS said.
To further encourage public use, USGS has also posted various videos that explain how to download and manipulate the maps.
