SMAP SDS Science Processing and Data Management System

NASA’s Jet Propulsion Laboratory, Pasadena, California The Science Processing and Data Management (SPDM) system’s primary functions are to control and monitor science processes and data products for Soil Moisture Active Passive (SMAP) Science Data System (SDS). SPDM adapts the Apache/OODT Framework 0.3 as the basic infrastructure. Although the OODT core framework is software-extensible, it provides limited, minimal, and rough functionalities. The adaptation effort has been extensive to fulfill SMAP SDS requirements including the integration of 26 processors with complex interactions among processors and files (≈70 static ancillary data types and ≈30 external dynamic ancillary types), pipeline automation to generate multiple products (LO-3) with large data volumes within a few hours to a few days of radar and radiometer instrument acquisition, monitoring and control of the data system, and interfacing with two NASA Data Active Archive Centers (DAACs).

Hyperlinked Overview of Piloted Evaluations (HOPE) Web- Based Data Archive

Langley Research Center, Hampton, Virginia The Hyperlinked Overview of Piloted Evaluations (HOPE) application provides an interface for users to enter data on pilots, metrics, configurations, tasks, and data collection sessions, as well as descriptive information for each item and the experiment as a whole. As this information is collected, hyperlinks allow other users (possibly without editing privilege) to peruse the database and see all runs for a given task or configuration, background information on evaluation subjects, simulation configuration, and summaries of various metrics.

GRAVITE Database

Goddard Space Flight Center, Greenbelt, Maryland Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE) system is a National Oceanic and Atmospheric Administration (NOAA) system, developed and deployed by Joint Polar Satellite System (JPSS) Ground Project to support Calibration and Validation (Cal/Val), Data Quality Monitoring, and Algorithm Investigation, Tuning and Integration. GRAVITE enables novice and expert users to discover and obtain data easily by using standard protocols. The Database is a component of the GRAVITE version 3.0 (GV3.0) system. It stores necessary information about archived files and corresponding metadata in a maintainable PostgreSQL database, and provides easy access to all GV3.0 components.

GRAVITE Monitor

Goddard Space Flight Center, Greenbelt, Maryland Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE) system is a National Oceanic and Atmospheric Ad - ministration (NOAA) system, developed and deployed by Joint Polar Satellite System (JPSS) Ground Project to support Calibration and Validation (Cal/Val), Data Quality Monitoring, and Algorithm Investigation, Tuning and Integration. GRAVITE enables novice and expert users to discover and obtain data easily by using standard protocols. The Monitor is a component of the GRAVITE version 3.0 (GV3.0) system. It monitors the status of the various components including those used from Apache OODT (Object Oriented Data Technology) and provides certain statistics. GV3.0 system has very large volumes of data arriving from multiple sources, and requires many PGEs (Product Generation Executable) to be run against the data. Operators must be able to analyze the incoming data without needing to examine every file individually. The general problem of monitoring a complex software environment via status and statistics is common and well documented.

Signal Processing for High-Temperature Health Monitoring of Condensed Water Height in Steam Pipes

An algorithm has been developed for monitoring the health of steam pipes to determine the height of condensed water through the wall in real time. NASA’s Jet Propulsion Laboratory, Pasadena, California An algorithm for analyzing wave reflections and time-of-flight ultrasonic pulse-echo data has been developed for monitoring the health of steam pipes to determine the height of condensed water through the wall in real time, at temperatures up to 250 °C.
