Title: IR DIAL performance modeling

Abstract

We are developing a DIAL performance model for CALIOPE at LLNL. The intent of the model is to provide quick and interactive parameter sensitivity calculations with immediate graphical output. A brief overview of the features of the performance model is given, along with an example of performance calculations for a non-CALIOPE application.

  • This paper describes the Sets and Fields (SAF) scientific data modeling system. It is a revolutionary approach to interoperation of high performance, scientific computing applications based upon rigorous, math-oriented data modeling principles. Previous technologies have required all applications to use the same data structures and/or meshes to represent scientific data or lead to an ever expanding set of incrementally different data structures and/or meshes. SAF addresses this problem by providing a small set of mathematical building blocks--sets, relations and fields--out of which a wide variety of scientific data can be characterized. Applications literally model their data by assembling these buildingmore » blocks. A short historical perspective, a conceptual model and an overview of SAF along with preliminary results from its use in a few ASCI codes are discussed.« less
  • We have recently completed a sensitivity study of unsaturated flow through a system of layered, fractured tuffs. This study was defined and performed for the International Hydrologic Code Intercomparison Project (HYDROCOIN). The modeled system was highly constrained and simplified but was loosely based on conditions though to exist at Yucca Mountain. The proposed paper will cover: a brief description of the system modeled, the mathematical model used, and the analyses performed for this study; a summary of the major conclusions drawn regarding the important types of flow behavior that were observed, and a discussion of the implications of the differentmore » types of flow behavior for performance allocation and for performance assessment using simplified models.« less
  • The Differential Absorption Lidar (DIAL) offers a way to perform ozone measurements in the troposphere with the spatial and temporal resolutions needed for both short and long term studies. Only a few DIAL systems have been used up to now for this purpose, relying mainly on tunable laser sources. In this paper, a new system using an Nd:YAG laser source and Raman shifting techniques to generate several wavelengths in the ultraviolet and the visible spectral range is proposed for use in a regional ozone network and in a small or medium size aircraft. This system has been operated in amore » ground-based station in southern France for nighttime ozone measurements in the free troposphere. A comparison with balloon borne Brewer-Mast ozonesonde data is presented and measurement accuracy of these two instruments is discussed. 17 refs.« less
  • The objective of our program has been the development and demonstration of systems for remote measurement of gases using discretely tunable high-energy gas lasers. Results reported here were obtained with two infrared lidar systems: A lidar system based on a deuterium fluoride laser for remote measurement of integrated concentrations of HCl, CH/sub 4/, and N/sub 2/O using scattering from topographic targets, and a lidar system based on a CO/sub 2/ laser for measuring range-resolved concentration profiles of water vapor using scattered radiation from naturally occurring aerosols. Performance predictions for both the DF and CO/sub 2/ lidars indicate that high-sensitivity, range-resolvedmore » measurements can be made of numerous gaseous species at 10 km range with commercially available components.« less
