OPAG on the Monitoring and Analysis of Climate Variability and Change
Organized under the World Meteorological Organization's (WMO) World Climate Data and Monitoring Programme (WCDMP), the Commission for Climatology (CCl) has three Open Programme Area Groups (OPAGs). OPAG 1 is on Climate Data and Data Management. OPAG 2 is on the Monitoring and Analysis of Climate Variability and Change. And OPAG 3 is on Climate Applications, Information and Prediction Services.
OPAG 2 is chaired by Thomas C. Peterson (USA) and co-chaired by Panmao Zhai
(China) and Abdallah Mokssit (Morocco). It consists of:
An article in the July 2003 issue of the WMO Bulletin on Detecting Climate Change describes many of the OPAG's past and future activities.
Statements of Guidance
The Frich et al. (2002) paper on observed coherent changes in climatic extremes during the second half of the 20th century used a carefully defined set of indices derived from daily observations of maximum temperature, minimum temperature and precipitation. Unfortunately, many areas of the world were not assessed by Frich et al. In an effort to facilitate and coordinate the analysis of a standard set of indices of extremes, simple software has been developed using widely available and easy to use spreadsheet technology. Called ClimDex, this software reproduces all the indices used in Frich et al. It was first used at a Caribbean Climate Change Workshop in January of 2001. An improvement on ClimDex, called RClimDex, was developed in 2004 by Environment Canada on behalf of the Expert Team on Climate Change Detection, Monitoring and Indices. The ET's indices web site also provides a FORTRAN version of the indices software.
World Weather Records
One of the major activities of Expert Team on Dataset Catalogues is the compilation of the 1991-2000 World Weather Records. Thanks to strong international collaboration, the World Weather Records is expected to continue to be one of the most geographically comprehensive in situ climate data sets in the world.
