Estimation of Tropospheric Fluctuations Using Gps Data: by C.J. Naudet

Introduction: Tropospheric delay fluctuations are a dominant error source for most classes of Ka-band (32-GHz) radio science experiments and high-frequency radio interferometry. This article reports on the use of the Global Positioning System (GPS) Flinn database to estimate the level of the tropospheric fluctuations at sites with GPS receivers. Development of a large database of the tropospheric seasonal, diurnal, and site fluctuations will serve many purposes. These me...

Excerpt: CSI's Section Format and Page Format) choose to number the Sub-Parts differently from what is currently allowed in SI. Instead of beginning their numbering with Part 1, and following with Subpart 1.1, and then with Subpart 1.2., they number utilizing Part 1, then Subpart 1.A, and following with Subpart 1.B. Our firm wants to use SI, but about 90% of our architectural clients don't use the numbering system as SI is currently configured...

Additional Request for Changing Report: by Jim Quinn

Excerpt: Explanation of Problem/Requirement Board Reviewed. Many people think of and discuss various SpecsIntact generated reports as Error Reports when in fact they are Quality Control Reports and should be identified as such. Some examples are: Address Verification Report (not an error if no intent to include section 01420 in the job); Submittal Verification Report (not an error if no intent to tag submittal items outside the submittal paragraph); Section Verification ...

The 1902 Glider: by National Aeronautics and Space Administration

Excerpt: The front of this poster describes the steps the Wrights took that led to the development of the 1902 glider. The Wright brothers first became seriously interested in solving the problem of human flight in 1899. After conducting extensive research, they concluded that the key to success lay in the pilot?s ability to control the aircraft. They proceeded to design, build, and test a series of aircraft that began with a kite in 1899, followed by three gliders in 19...

Space Shuttle Program 1999 Annual Report: by National Aeronautics ...

Excerpt: 1999 was a productive and challenging year for the Space Shuttle Program (SSP). We have continued to strive to meet our Program goals to fly safely, to meet the manifest, to improve mission supportability, and to improve the system. We accomplished four safe and successful missions. On STS-95, a research flight, we returned John Glenn to space and obtained key scientific data on the similarities between the effects of microgravity and the aging process. We succe...

The Evolution of the Darwin System: by Joan D. Walton

Abstract: DARWIN is a web-based system for presenting the results of wind-tunnel testing and computational model analyses to aerospace designers. DARWIN captures the data, maintains the information, and manages derived knowledge (e.g. visualizations) of large quantities of aerospace data. In addition, it provides tools and an environment for distributed collaborative engineering. We are currently constructing the third version of the DARWIN software system. DARWIN?s deve...

A Banner Year for the Space Shuttle: by Ronald D. Dittemore

Excerpt: We have flown seven flawless missions in Fiscal Year 2001, starting with STS-92 in October and finishing with STS-105 in August. These seven flights, dedicated to the construction of the International Space Station (ISS), delivered more than 45 tons of hardware. From the launch of STS-98 in February to the landing of STS-105 in August, we have flown five flights in 6 months, maintaining a vehicle in orbit for more than one-third of that time. This is a great tri...

Capturing Time and Vertical Variability of Tropospheric Ozone : A ...

Excerpt: In this paper, the vertical resolution for Tropospheric Emission Spectrometer (TES) nadir ozone retrievals is established and is used to assess the ability of TES to capture time variations of ozone in the troposphere. This characterization is based on retrievals of ozone using simulated radiances generated from ozonesonde profiles taken over Bermuda from 14 April to 25 May 1993. To that end, a two-step retrieval strategy that includes an initial estimate of the...

Contributions of a Multimoment Multispecies Approach in Modeling P...

Excerpt: Classic approaches in modeling planetary atmospheres, which are based on kinetic transport coefficients, have an upper limitation in altitude due to the transition from collision to non-collision regions; consequently, models developed until now have been constrained under the exobase. Furthermore, such models require hypotheses for diffusion coefficients, thermal conductivity, and viscosity in the case where several major species coexist in the medium. In order...
