Average Difference in Leaf Area Index for Houston Metro Area between 2001 and 2002.
This 5 kilometer resolution image of the Houston area shows the differences in Leaf Area Index (LAI) as an average for August between 2001 and 2002. MODIS LAI measurements show, that on average for August between 2001 and 2002, leaf area in some areas within Houston decreased, likely associated with development in the metropolitan area. Non-urban areas to the northwest and west of the city show higher LAI values compared to the 2001-2002 average, indicating more vegetation. This slide underscores the importance of using current LAI data (rather than climatological, as is standard) in models like LIS. Credit: NASA/Land Information Systems
Houston Area Temperatures, August 22, 2002
Surface temperature on August 22, 2002 at 20:00 Greenwich Mean Time (GMT) for the Houston area as predicted by the Land Information System (LIS). As shown, the temperatures in the Houston area are 1-2 degrees Kelvin (K) (1.8-3.6 F) warmer than the surrounding areas. The black areas are lakes or water bodies, which are not currently modeled by the Land Information System. Credit: Credit: NASA/Land Information Systems
Satellites and computers are getting so good, that now they can help study human activity on scales as local as ones own neighborhood, and may answer questions concerning how local conditions affect global processes, like water and energy cycles.
NASAs Land Information System (LIS) uses computer models to predict impacts that cities and other local land surfaces might have on regional and global land and atmospheric processes. Dr. Christa Peters-Lidard, Co-Principal Investigator and Project Manager for LIS, at NASAs Goddard Space Flight Center (GSFC) in Greenbelt, Md., gave a presentation on LIS this week at the annual meeting of the American Meteorological Society in Seattle.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
