After more than 3 years in development, the Man-computer Interactive Data Access System (McIDAS) has left the “beta” designation and is now an operationally supported software toolkit. This fifth generation of McIDAS is a Java-based, open-source system designed to support new environmental satellite observations and their multispectral and hyperspectral researchers and algorithm developers.
McIDAS-V provides powerful new data manipulation and visualization tools to work in this data rich environment. Unlike most other 2-D weather display tools, the multi-dimensional display capability brings weather data into the three-dimensional world with powerful new display capabilities. This new data analysis and visualization system will support both researchers and operational users of the advanced measurement systems on GOES-R, JPSS, and Metop.
McIDAS had its origins in the early 1970’s. The data analysis and visualization capabilities of this system were state-of-the-art for many years and continue to provide powerful tools even 35 years later. The software is used by many atmospheric scientists in research, operations and industry.
McIDAS-V is a software ensemble containing many features. It builds upon several years of VisAD and IDV development to enhance functionality. McIDAS-V will integrate the multi- and hyperspectral satellite data capabilities from HYDRA and allow a two-way dialog with a McIDAS-X session to make those data and products available. In addition to these powerful attributes, McIDAS-V offers improved data and server management and a friendly, user-configurable interface. Finally, since the software is freely available and open source, we will add our own and our collaborators’ improvements to continue to evolve the capabilities of the software.
Learn more about McIDAS-V and download the software, user manuals, and training materials, at our new web site.We also encourage you to take advantage of the McIDAS Users Group.
On 17 September 2010 the Ice Drill Design and Operations (IDDO) group at the UW-Madison Space Science and Engineering Center presented their Blue Ice Drill for review to Jeff Severinghaus, Principal Investigator of the National Science Foundation’s Office of Polar Programs.
Professor Emeritus Charles Bentley, Principal Investigator of Ice Coring and Drilling Services, examines the barrel of the Blue Ice Drill.
The IDDO group designed, built, and tested the new drill. Developed specifically to take samples from blue ice – a dense, extremely hard ice formed deep under the Antarctic ice sheet by the incredible pressure of hundreds, even thousands, of meters of ice above it. If a flowing glacier meets an immovable geological structure, such as a mountain, the blue ice at the bottom of the glacier can be forced to the surface. As the years pass, the oldest ice in the glacier is exposed to the light, and to researchers’ drills.
Studying the bubbles of ancient atmosphere trapped in the ice can reveal much about the Earth’s climate in millennia past.
The drill was designed with simplicity in mind. Generally, three scientists and two technicians will be present on site for the drilling, but as few as two people can operate the device. The drill cuts a very large core sample: 24 cm thick and a meter deep. One of the challenges facing the IDDO team was snapping the core of super-hardened ice off of its parent glacier at depth in a narrow, confined bore hole. A second piece of equipment, the Core Recovery Drill, is sent down into the hole where a piston on the side of the recovery tool drives the sample horizontally.

The drill can bore 12 meters down into the ice and produce 7 sample cores per day. The disassembled drill is small and light enough (at most 500kg/1100lbs) to fit into a Bell 212 helicopter.
The Blue Ice Drill passed its review with flying colors. The drill will be deployed this season in Antarctica.
The IDDO group presented the Blue Ice drill for Jeff Severinghaus’ (NSF Principal Investigator - kneeling) approval.

A team from the Cooperative Institute for Meteorological Satellite Studies (CIMSS) returned this week from St. Croix, U.S. Virgin Islands, the operations center of the NSF-sponsored PRE-Depression Investigation of Cloud systems in the Tropics (PREDICT) experiment. PREDICT, a major collaborative tri-agency (NOAA/NASA/NSF) hurricane field project, is designed to study the genesis and rapid intensification of tropical cyclones in the Atlantic.
Prediction and understanding of tropical cyclogenesis remains one of the most challenging aspects of atmospheric science. A multitude of tropical disturbances emerge from the West African coast near the Cape Verde islands every year, but only a few of these develop into tropical depressions, storms, or hurricanes.
Scientists from CIMSS are supplying satellite expertise and support for the project, including hurricane diagnostic algorithms based on polar and geostationary satellites, and is participating directly in real-time mission planning/coordination, forecasting, nowcasting, and data analysis.
The PREDICT field experiment deployed the NSF/NCAR Gulfstream V aircraft in the Atlantic basin in the heart of hurricane season, 15 August - 30 September 2010, to explore multi-scale interactions in tropical wave-like disturbances that promote or hinder the development of a tropical depression vortex.
The U.S. Virgin Islands was chosen because it offers the best range for the Gulfstream V to cover the area of interest to the scientists and because of its airport and support facilities.
PREDICT is one project in a tri-agency collaborative study of the formation of tropical hurricanes. The National Center for Atmospheric Research (NCAR), National Aeronautics and Space Administration (NASA) and National Oceanic and Atmospheric Administration (NOAA) will collaborate and coordinate multi-aircraft deployments over the tropical Atlantic Ocean. These three projects are being deployed simultaneously, each having their own specific hypotheses and agenda, however each are complimenting the others.
NESDIS is providing support through GOES-East, and special rapid-scan datasets being provided as part of the GOES-15 science checkout. The multi-platform observations from this summer's hurricane project will be used in research analysis for years to come. The project ended on 1 October 2010.

UW undergrads from several disciplines are participating in a joint NASA/National Space Grant Foundation effort to design, build, and test an inflatable, hard-shell habitat that astronauts can transport to their destination (in orbit, the Moon, Mars) and use to expand their living quarters.
"This project will allow us to improve upon an already excellent educational design course model, specifically in the area of systems engineering, while attracting a broad range of organizations," says Fred Best, SSEC technical director. "I think this group of students is going to be very successful and I hope to see more collaboration like this in the future."
SSEC is supplying outreach funds for the project, enabling students to connect with various experts and a private systems engineer.
The UW College of Engineering has posted a complete article on the project.
