Introduction

The Data Extractor was developed to fill a requirement of both the BADC and the NERC DataGrid.

The Data Extractor has a sister package called GeoSPlAT (GeoSpatial Plotting and Animation Tool) that provides a graphics interface to data generated by the Extractor.

What does the Data Extractor do?

Please see the BADC Data Extractor web page for more details.

Requirements

The Data Extractor relies on the following software (no version testing has been done so far):

A webserver (probably Apache).
CDAT (Climate Data Analysis Tools) - available for numerous platforms.
Python - if not installed with CDAT.

Documentation

We are currently working on documentation for the Data Extractor. Please see the BADC Data Extractor web page for more details.

Download

Version 0.1 of the Data Extractor is currently being tested and will soon be made available via this web site. Please let me know if you need it urgently.

Future plans

Please see the BADC Data Extractor web page for more details.

Acknowledgements

Thanks to the CDAT team for providing a tool that I could build upon to develop the Data Extractor. Thanks to numerous colleagues at the BADC and NDG for you guidance.

Note that I am looking for collaborators to expand the functionality of the Data Extractor. Contact me if you are interested.
