Visiting Scientists and Research Associates
Ms. Jayanthi Srikishen and Ms. Vada LaFontaine completed their appointments as Research
Associate Irs on this contract.
Mr. Mathew Smith served as a Visiting Scientist to work as the Applications Consultation focal
person with the Earth Science and Application Divisions Data Systems .group. He assisted in
solving local and remote user problems for USRA and MSFC scientists. Mr. Smith was
responsible for running the MclDAS Users' Group Meetings at MSFC.
Dr. Jeh Won Lee served as a Visiting Scientist to investigate the Hubble Space Telescope
problem, May 1, 1990. He downlinked the flight data to the VAX and its frequency characteristic
was analyzed using a power spectrum density plot. The effect of a solar array dynamics on the
main body dynamics was studied using TREETOPS model and the point controller was
redesigned. His work focused mainly on the verification and application of the TREETOPS
model which was a time history simulation program for a flexible multi-body dynamics.
Dr. Young Kim was appointed as a Visiting Scientist through July 1993, to develop a Multi-body
Modeling Verification and Control (MMVC) System. The dynamics simulation and control
system design of multi-body structures was performed using the NASTRAN, MATLAB and
TREETOPS, which is a multi-body dynamics control simulation. He performed a structural
dynamic analysis of the flexible dipole antenna. He developed a solar x-ray imager (SXI)
telescope design; a dynamics simulation and control model of the SXI with interaction of the
Geostationary Operational Environmental Satellite (GOES) spacecraft, and a preliminary pointing
control analysis of the SXI by using NASTRAN and TREETOPS. He participated in the Error
Budget Team of the SXI telescope design, and studied the X-ray Positioner (XRP) and Solar
Array Stability.
1. Activities Performed
Ms. Jayanthi Srikishen assisted scientists in developing numerical models. During this project,
Ms. Sfikishen generated read tapes on many machines, such as the IBM and the VAX. She
compiled file transfers between the VAX & the IBM and the VAX & the PC. She has designed
and maintained databases consisting of users on the EADS system and made them readily
available for all users. She has demonstrated programs for the CRAY on the EADS for the user
community and helped users with problems.
She worked on the GENESIS and GCM Models on the CRAY. She conducted modifications to
the RAMS Model and implemented the LAMPS90 on the CRAY X-MP.
Ms. Srikishen utilized the graphics package "GRADS" for visualizing the model output on the
LAMPS Model. She also consistently trained scientists and others to use the updates and all new
computing packages and the data storage facility under EADS II. She installed the NCAR
Community Climate Model to the CRAY Disk at MSFC. She served as troubleshooter and
assisted users in debugging and solving problems.
Ms. C. Vada LaFontaine focused her participation on assisting scientists in the WetNet
development and supporting hardware setup, its policies and promoting data availability. She
continued to support WetNet scientists on hardware and sottware problems and MclDAS
command questions. She completed the WetNet manual tutorial and participated in several
WetNet training sessions throughout the United States. The WetNet group produced a series of
datasets and Ms, LaFontaine supervised the reproduction and distribution of these datasets to all
WetNet System Scientists.

3. Subcontracts
USRA entered into a subcontracting relationship with Mesoscale Environmental Simulations
and Operations, Inc., from February 9, 1987, through July 22 1991. Key personnel were
Kenneth T. Waight III, J. Aaron Song, John W. Zack, and Pamela E. Price. This subcontract
entitled, "Model Studies on the Role of Moist Convection as a Mechanism for Interaction
Between the Mesoscales," was a three year research effort to develop techniques to improve
the numerical prediction of cumulus convection on the meso-13 and meso-_, scales. Two MESO
models were used, the MASS (mesoscale) and the TASS (cloud scale) models. The primary
meteorological situation studied was the June 28-29, 1986 COHMEX case study, in which
significant mesoscale precipitation occurred over the COHMEX study area on a day with
relatively weak large scale forcing.
Five conference preprints were produced as a result of this effort:

and Forecasting, Monterey, American Meteor. Soc., 569-574, 1989.

Information in Simulations of a Complex Summertime Precipitation Event," The 12th
Conference on Weather Analysis and Forecasting, Monterey, American Meteo. Soc., 121-124,
1989.
Song, J. A., "A Numerical Investigation of an Enhanced Rainfall Due to Multi-Scale
Processes Observed on June 28 of COHMEX," The Conference on Operational Precipitation
Estimation and Prediction, Anaheim, American Meteor. Soc., 1990.
Song, J. A., and M. Kaplan, "Thunderstorm Initiation as a Result of Scale-Interactions," The
Fourth Conference on Mesoscale Processes, Boulder, American Meteor. Soc., 102-103, 1990.
Waight, K. T., and J. W. Zack, "An Analysis of a Small Mesoscale Convective System
During COHMEX," The Fourth Conference on Mesoscale Processes, Boulder, American
Meteor. Soc., 100-101, 1990.
Song, I. A. and M. L. Kaplan, "Observation and Numerical Simulation of a Convective
Initiation During COHMEX, NASA Technical Memorandum, 1990.
Also produced as a result of this subcontract:
1. A MASS Preprocessor User's Guide and the MASS Model User's Guide,
documentation for MASS.
2. The TASS User's Guide, documentation for the TASS Model.
A Final Report which describes MESO's accomplishments remains on file at the USRA
Corporate Drive Office in Huntsville, Alabama.
USRA entered into a subcontracting relationship with Utah State University, September 1993,
to provide logistic support for the NASA WETNET Meeting which was held at Utah State
University Conference and Institute Division.

review of a couple of chapters for the Terrestrial Envirent
Criteria Guidlines Document. Plans and preparation have
been made to review the complete document when in draft
form. Some discussions have been held with Mr. Dale Johnson
and Mr. Kelly Hill in this regard.
(4) Various items the literature have been reviewed
and selected topics and materials brought to the attention
of various members of the Earth Science and Applications
Division.
