This software provides storage retrieval and analysis functionality for managing satellite altimetry data. It improves the efficiency and analysis capabilities of existing database software with improved flexibility and documentation. It offers flexibility in the type of data that can be stored. There is efficient retrieval either across the spatial domain or the time domain. Built-in analysis tools are provided for frequently performed altimetry tasks.

This software package is used for storing and manipulating satellite measurement data. It was developed with a focus on handling the requirements of repeattrack altimetry missions such as Topex and Jason. It was, however, designed to work with a wide variety of satellite measurement data [e.g., Gravity Recovery And Climate Experiment — GRACE). The software consists of several command- line tools for importing, retrieving, and analyzing satellite measurement data.

This work was done by Robert deCarvalho, Shailen D. Desai, Bruce J. Haines, Gerhard L. Kruizinga, and Christopher Gilmer of Caltech for NASA’s Jet Propulsion Laboratory. For more information, contact iaoffice@
