The focus of the Climate Working Group has developed further and slightly changed during the last years. However, this is not yet reflected on the current webpage. Parts of the webpage are currently outdated and some links might not be available any more. The page will be updated in the near future. We apologize for any inconvenience.

About the working group

Since the first International TOVS Study Conference (ITSC) held in Austria (1983), the ITSCs significantly evolved and formed numerous working groups and subgroups. The Climate Working Sub-Group (CWSG) now has access to data records in excess of 25 years. Accordingly, the objective of this working sub-group is continuing to improve the management, integrity, quantity, quality and collaboration of climate products as more centers fall in to support Climate Data Record (CDR) production in operations around the world.

The ability to access and share both historical, current and planned climate products and data (both raw and meta-data) has become an essential requirement that empowers leaders to make informed, confident decisions based upon solid and credible recommendations from subject matter experts.

Climate Data Record (CDR) Measurement Maturity Index

As the data records from satellites have become longer and the science of applying these data to climate problems has evolved, best practices for compiling CDRs have emerged. The objectives in compiling these best practices into an assessment model has arisen in order to:

  1. Reduce difficulty and confusion in the community about what attributes are important in climate data records,
  2. Produce an easily understood way of identifying maturity of data products and science data stewardship approaches, and
  3. Help identify areas needing improvement.

In an effort to capture these best practices and assess the maturity of various CDRs, three dimensions for assessing the maturity of a CDR have initially been proposed; scientific maturity, preservation maturity, and societal benefits. The particular maturity level is assessed by defining the set of key process areas and the level of best practices that characterize each area. The result is a score ranging from 1 (very low) to 5 (very high)that can be used to provide a rating of the total maturity of a specific climate data record. Essential Climate Variable (ECV) Societal Impact and ECV IPCC Impact Indices in HTML format.are anticipated to be available for review, consideration and input from subject matter experts in the near future.

ITSC working group reports

At every ITSC the group meets to discuss developments and issues arising in the areas of interest to the working group, listed above. PDF copies of the resulting reports will be provided here.

The Meteorological Satellite Center (MSC), an auxiliary component of the JMA, was established in April, 1977. The MSC is located in the City of Kiyose, a suberb of Tokyo, except the Command and Data Acquisition Station (CDAS)is located in the town of Hatoyama northwest of Tokyo.

  • NOAA's National Operational Model Archive and Distribution System (NOMADS) addresses the growing need for remote access to high volume numerical weather prediction and global climate models and data. NOMADS was initiated by the National Climatic Data Center (NCDC), National Centers for Environmental Prediction (NCEP) and the Geophysical Fluid Dynamics Laboratory (GFDL). NOMADS provides both real-time and historical Numerical Weather Prediction (NWP) models and other datasets as a distributed format nuetral Web Service
