ABoVE Permafrost Dynamics Observatory
chercheur principal:
Année(s) de permis: 2019
Résumé: The objective of this project is to collect physical and geophysical measurements quantifying permafrost susceptibility to ABoVE's internationally-available dataset. Researchers can access these data to bolster understanding of environmental processes and the ability to remotely-sense these on a regional scale. Airborne remote sensing missions from August 2017, 2018, and August of 2019 by NASA'...

Remote Sensing and Geophysics of Tundra Landscapes
chercheur principal:
Année(s) de permis: 2019 2018
Résumé: The proposed project will investigate the possibility of linking field-measured characteristics of tundra landscapes (e.g., active layer thickness, soil moisture, plant distribution and ecosystem composition, etc.) with remotely-sensed data. The overall objective of the project is to identify the connections that exist between observable surface properties and their associated subsurface/permafros...

FIRE III: An Arctic Cloud Study
chercheur principal:
Année(s) de permis: 1998
Résumé: Arctic clouds are dominant on average covering 40 to 60% of the skies over the Arctic ocean. They exert a large influence on the radiation balance in the Arctic, where climate change effects are predicted and observed to be largest in the northern hemisphere. The FIRE III field project will use in-situ measurements obtained using instrumental aircraft, in combination with concurrent satellite dta,...
