The Guide to Climatological Practices is designed to provide guidance and assistance to World Meteorological Organization (WMO) Members in developing national activities linked to climate information and services.
There have been two previous editions of the Guide, the original published in 1960, and the Second Edition published in 1983. While many basic fundamentals of climate science and climatological practices have remained consistent over time, scientific advances in climatological knowledge and data analysis techniques, as well as changes in technology,
computer capabilities and
instrumentation, have made the Second Edition obsolete.
The Third Edition describes basic principles and modern practices important in the development and implementation of all climate services, and provides methods of best practice in climatology. It is intended to describe concepts and considerations, and provides references to other technical guidance and information sources rather than attempting to be all‑inclusive in the guidance presented.Guide to Climatological Practices (Third Edition)
