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.

Recent updates
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:
- Reduce difficulty and confusion in the community about what attributes are important in climate data records,
- Produce an easily understood way of identifying maturity of data products and science data stewardship approaches, and
- 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.
Reanalysis and Satellite Sensor Information:
The Japan Meteorological Agency (JMA) is currently working on action Climate-8 and ITSC-15. JMA will post any information on reanalysis and satellite-sensor to include metadata updates on the ITWG web site. Dr. Masami Sakamoto has completed work on geometric error lists and associated documentation to include compliation of TBB quality lists. An Error List Production in accordance with (IAW) the following recommendations in ITSC-15 will be completd:
-
Recommendation Climate-4: Reanalysis groups should seek to work with the operational satellite climate centres on the optimal calibration and processing of archived data sets. Additionaly, the Reanalysis Groups should send back to the relative operational centre any Meta Data obtained during or after the reanalysis.
-
Recommendation Climate-7: Reprocessing and Reanalysis Centres to provide reanalysed, or reprocessed satellite data, together with their metadata to the original archiving centre.

POES: NOAA/NESDIS/Office of Satellite Operations providing an instrument status update for the Polar Orbiting Environmental Satellites
-
NPOESS (Future): The National Polar-orbiting Operational Environmental Satellite System is a satellite system used to monitor global environmental conditions, and collect and disseminate data related to: weather, atmosphere, oceans, land and near-space environment.
-
IJPS: The Initial Joint Polar-Orbiting Operational Satellite System is the result of a cooperative effort between the National Oceanic and Atmospheric Administration ( NOAA) and the European Organization for the Exploitation of Meteorological Satellites ( EUMETSAT).
-
MTSAT The Japan Meteorological Agency (JMA)has been operating geostationary meteorological satellites since 1977. 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.
-
Japan Aerospace Exploration Agency (JAXA) JAXA's Earth Obervation Research Center (EORC) was established in April 1995, and is a core element for the analysis and research of Earth observation satellite data, The JAXA EORC performs calibration and validation for observed data and observation instruments aboard Earth observation satellites as well as ADEOS (Midori), developing higher-level algorithms, and experimentally generating research products.
INSITU STATUS:
-
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
INSTRUMENT STATUS
-
POES:
NOAA/NESDIS/Office of Satellite Operations providing an instrument status update for the Polar Orbiting Environmental Satellites. POES Level 1B Notices from NOAA/NESDIS/OSDPD – History of notifications including visible calibration updates, instrument performance changes, format changes, version changes, corrections, etc.
DATA SOURCE ACCESS
-
-
Comprehensive Large Array-data Stewardship System (CLASS) Radiance data from polar-orbiting and geo-stationary satellites (MetOp and POES; GOES; and DMSP), as well as, satellite derived products. Free delivery via FTP and HTTP, otherwise, contact CLASS Help Desk for bulk order delivery. Subscription services for near real-time data available upon request.
-
-
Scientific Data Stewardship (SDS) for assistance to agencies and organizations in prioritizing measurement strategies for understanding, detecting, and adapting to climate change. SDS helps foster wide participation in the process of developing measurement strategies and informs interested individuals and organizations about the connections between climate, climate change, and measurements. IPCC Issues and ECVs are discussed in conjunction with Societal benefits and impacts.
