Recent research has provided evidence that the emergence of rapid Arctic warming in recent decades has coincided with unusually cold winters over Northern Hemisphere continents. The High Latitude Cold Regions (HLCR), especially the Arctic Ocean, have a profound influence to northern hemisphere weather and climate, which further extends to provide a global impact. The High Altitude Mountain Cold Regions (HAMCR), in particular Qinghai-Tibet Plateau, contribute to the climate change through the water and energy cycle and other modulating mechanisms. Improving the understanding of the interconnection and teleconnection between HLCR, especially the Arctic, and HAMCR is becoming a key challenge. From the perspective of the Earth climate system, there is a need for the sustainable observations, and development of new methodologies to better characterize the evolution of the cryosphere, ecosystem, and atmosphere.
Given the amount of available historical Earth Observation (EO) data, as well as the fast evolution of interpretation methods of satellite observations and various numerical modelling approaches, a “three poles comparative study” became feasible for ensuring better understanding the changing synchronism and asynchronism mechanism among Earth poles. This special theme under International Journal of Digital Earth (IJDE) is devoted to the latest study on earth observations and understanding of impact to the change of HLCR and HAMCR, especially the interconnection and relationship among these regions, which will provide an up-to-data observations products and modeling for the sustainable research of cold regions.
This is an open call for papers. Papers from the 2nd Pan-Eurasian Experiment (PEEX) Science Conference in the thematic of a) Earth observations for Arctic and cold regions and, b) Impacts of climate change and cryospheric changes will also be invited for submission.
Submissions are encouraged to cover a broad range of potential topics that may include, but are not limited to:
- Methodology on retrieval of remote sensing and assimilation with in-situ measurement for cryosphere (glacier, snow, sea ice, lake ice, permafrost), atmosphere (precipitation, aerosol) and ecosystem (vegetation, land cover, land use) over Earth poles.
- Climatology environmental data products and their changing analysis over Earth poles in last decades.
- Retrieval of remote sensing data on better understanding of the air-snow-sea interaction in HLCR.
- Modeling and process understanding to the land-ocean-atmosphere-cryosphere interaction in HLCR.
- Boreal and High Mountain lakes observations and its impact and feedback to climate change.
- Marco phenomena comparative study through space-based earth observation for Earth poles to understanding the changing synchronism and asynchronism mechanism.
