The result of a study on the application an improved statistical prediction method for estimating intermediate‐term (months) and long‐term (years) behavior solar flux is discussed. indicates that better predictions, in chi square sense, are possible by selecting sets data such each set (cycle) starts ends at maxima (or minima) base initialization point procedure. Then one applies Lagrangian least‐squares technique. Evidence also presented to support existence aperiodic variation periods as...

Coherent Doppler lidar appears to hold great promise in contributing the basic store of knowledge concerning flow field characteristics nonprecipitous regions surrounding severe storms. The lidar, through its ability measure clear air returns, augments conventional radar system, which is most useful precipitous storm. A brief description storm measurement system provided along with technique be used performing measurements. application addressed, and planned program outlined.

A NASA project spans the gap between research and operations, introducing new composites of satellite imagery to weather forecasters prepare for next generation satellites.

In the present study we extend previous work from this laboratory on polypeptide composition of photosynthetic lamellae. Using a high resolution sodium dodecyl sulfate gel electrophoresis technique, show that both grana and stroma lamellae have qualitatively very similar compositions although some clear quantitative differences are demonstrated.

Covers advancements in spacecraft and tactical strategic missile systems, including subsystem design application, mission analysis, materials structures, developments space sciences, processing manufacturing, operations, applications of technologies to other fields.

The natural terrestrial environment plays a significant role in the design and operation of aerospace vehicles (space rockets) associated integrity systems elements. Addressed herein are some key vehicle areas concern plus “lessons learned” that have been identified over number years. Many these meteorology related events occurred during development interpretation inputs, especially those environment, used Saturn Apollo Space Shuttle mission operations. Background is given regarding actions...

The results of a questionnaire designed to gather information on how nonmeteorological scientists and engineers view meteorology weather forecasting are summarized in this paper. respondents were from two organizations, Texas A&M University NASA's Marshall Space Flight Center, the first representing academic community latter engineering community. While there some differences between groups, most cases answers expressed opinionnaire by groups essentially identical. revealed following:...

The meteorological satellite program began in the United States as result of actions taken by a very small but dedicated group people from late 1940s to 1960. This paper provides firsthand accounts two these individuals. Their remarks provide an insight into trials and tribulations they encountered during early years. Those now active program, many whom do not recall this time, might appreciate effort pioneers legacy left for us.

This paper discusses the role of applied meteorology in solution large space vehicle development problems. A general outline meteorologist is given, followed by a discussion data requirements for design and test evaluation, analytical procedures presentation, areas influence on development. Examples atmospheric conditions are presented illustrating utility meteorology.

Natural (Terrestrial & Space) Environment (NE) phenomena play a significant role in the design and flight of aerospace vehicles integrity associated systems structures. environmental criteria guidelines described here are based on measurements modeling atmospheric climatic relative to various vehicle development mission/operational procedures, for launch locations. Both terrestrial environment (0-90 km altitude) space (Earth orbital altitudes) parameters their engineering application...

Aerospace meteorology plays an important role in the design, development, and operation of aerospace vehicles. Many issues lessons presented occurred during involvement authors with development interpretation environment inputs, especially those terrestrial environment. Background for actions needed to avoid issue being repeated or lesson having be relearned is addressed. The engineering application importance some associated presentation guidelines elements are presented.
