In the last fifty years, models and observations have enabled us to better understand sea-ice processes. On the one hand, global climate models have been developed, accounting for the sea-ice component in the climate system. On the other hand, satellite instruments have been developed to monitor the “real” sea-ice evolution. These satellite observations are often used to evaluate climate models. H ...[Read More]
Image of the Week – Of comparing oranges and apples in the sea-ice context
Fig. 1: Model-to-observation comparison of sea-ice variables might best be conducted at a middle-ground "location" (along the x axis) somewhere in between what the models compute (left) and what satellites observe at the top of the atmosphere (right). Obs Oper = Observation Operators, SIC = sea-ice concentration, ISF = ice surface fraction [Credit: Lavergne, 2017 ].
