Periodic Reporting for period 2 - IVORI (New Insights on the Snow Cover: From Snowflakes to Ice Sheets, in Seconds to Centuries.)
Período documentado: 2022-08-01 hasta 2024-01-31
(1) Understand the role of water vapour transport in snow and its subsequent impacts on the ground thermal regime governing permafrost evolution;
(2) Understand how initial changes in surface snow microstructure are transferred deeper into the firn and affect ice core records;
(3) Determine the contributions of snow-climate feedbacks, triggered by changes in the albedo and insulating capacity of snow to the past and future of snow cover and ground temperature.
The model will provide a reliable assessment of snow-climate feedbacks in a changing climate and a rigorous appraisal of the modelling uncertainties. When completed, this work will pave the way for crucial advances in our understanding of glaciers, ice sheets and past climate through ice core records, with many fallouts for sea ice and permafrost evolution.
