CL1.2 –  Past Climate - Last ~2.6 Ma

Sub-Programme Group Scientific Officers: Jan-Berend Stuut, Carole Nehme

CL2 –  Present Climate – Historical and Direct Observations

Sub-Programme Group Scientific Officers: Martin Wild, Kerstin Treydte

Proposals are marked in red.

Session short summary:
This session highlights high-quality in-situ, satellite, and reanalyses data in climate research. It focuses on quality control, harmonization, and homogenization of observations. Key topics include data assimilation, physical retrievals, and AI/ML techniques. Ultimately, the session evaluates the impact of these data on ECVs, climate services, and extreme event attribution.
Keywords: Climate extremes, Data assimilation, Machine Learning, Satellite time series, Synoptic climatology (Climate observations)
