Satellite-based climate studies critically depend on consistent and homogenized data records of sufficient length (i.e., decadal to multi-decadal) for the purpose of better detecting and understanding climate variability and trends. The creation of such records requires the merging of data from different instruments and satellite missions via sophisticated intercalibration processes. The development of products using such processes has led to an internationally-recognized class of satellite products often referred to as Climate Data Records (CDRs) as well as to a formal framework and taxonomy in terms of Essential Climate Variables (ECVs).
Given the launch of next-generation sensors that have higher radiometric, spatial, and temporal resolutions, and more stable orbits, the purpose of this session is to facilitate consideration of the challenges and opportunities that exist in ensuring the continuity of critical legacy products and in incorporating data from newer sensor platforms. Presentations and posters from developers and users of satellite CDRs and ECVs are welcome. Of particular interest are those that cover the following topics:
- the state of the science of the sensors, processing algorithms, and intercalibration methods involved in producing both fundamental CDRs and the ECVs, or thematic CDRs, derived from them;
- evaluations and applications of CDRs and ECV data products; and
- the status of existing CDRs and ECVs, along with related developmental activities associated with overlaps between legacy products and products that involve newer sensors.
At this time of multiple satellite sensor transitions, the session directly supports the annual meeting theme of "The AMS Past, Present and Future: Linking Information to Knowledge to Society" in that it covers well-established products, state-of-the-art techniques, and new technologies. The organizers hope that it will also enhance communication among government scientists, non-government experts, and data users from all sectors about the salient issues surrounding the continuity of fundamental and thematic CDRs.
