Atmosphere and Cryosphere are closely linked and need to be investigated as an interdisciplinary subject. Most of the cryospheric areas have undergone severe changes in last decades , while being some of the areas more fragile and less adaptable to global climate changes. This AS-CR session invites model- and observational-based investigations of linkages between atmospheric, land and ocean processes and snow and ice on local, regional and global scales. In particular, we encourage studies that address aerosols (such as Black Carbon, Organic Carbon, dust, volcanic ash, diatoms, bioaerosols, bacteria etc.) and changes in the cryosphere, e.g., effects on snow/ice melt and albedo. Contributions on the following topics are also particularly welcomed: dust transport, aeolian deposition, volcanic dust, including health, environmental or climate impacts at high latitudes, high altitudes and cold polar regions. In addition, for trustworthy computational predictions of future climate change, these interactions need to be taken into account by eScience tools. In particular, this requires: 1) Integration of existing measurement data and enhanced information flow between disciplines; 2) Representation of the current process understanding in Earth System Models (ESMs) for which computational limitations require balancing the process simplifications; and 3) Improved process understanding. eScience such as High-Performance Computing (HPC), big data or scientific workflows is central in all of these areas.
