Land-climate interactions play a key role in the climate system, but are difficult to investigate due to the scarcity of relevant observations, the complexity of the underlying processes and feedbacks, as well as the wide range of scales that they involve. The aim of this session is to bring together studies investigating land-climate interactions from various perspectives, i.e. for past, present or future climate, using observational, diagnostic or modeling approaches, and on scales ranging from local to global.

We encourage in particular the following topics for contributions:
(i) Analysis of models and observations (validation, process studies); conceptual models based on existing data
(ii) Interfaces between the energy, water and carbon cycles
(iii) Role of soil moisture, vegetation (ecosystem exchanges, plant physiology, phenology, dynamic vegetation), boundary-layer processes, snow, radiation, albedo
(iv) Land initialization for seasonal forecasting
(v) Memory effects, climate persistence
(vi) Relevance of land-climate interactions for climate variability and extreme events (in particular, droughts, heatwaves, and heavy precipitation events)
(vii) Land-climate interactions in the context of climate change
