what is GAW

The Global Atmosphere Watch (GAW) is a WMO Programme to provide scientific data and information on the chemical composition of the atmosphere and its natural and anthropogenic change, and to improve the understanding of interactions between the atmosphere, the oceans and the biosphere. source: WMO Website http://www.wmo.int/pages/prog/arep/gaw/gaw_home_en.html

introduction

• 8 out of 10 received records are not well-formed XML

• style: keywords from unclear sources

well-formedness

• ill-formed records are due to raw ampersand '&' in xlink:href attribute
• please be careful not to create ill-formed XML

Precision-based heuristic algorithm to identify types of BUFR TEMP messages

TOYODA Eizi

Introduction

Here I show an algorithm to identify types of BUFR TEMPs to tell whether the message is native or reformatted, and what part(s) are used for reformatting. An implementation is found here. Both are just a quick hack that worked with bulletins of small number of days. NO WARRANTY.

Design Principles

Avoid relying on external database
