Environmental changes in terrestrial ecosystems and coastal areas across the Arctic can only be fully addressed by using remote sensing observations and modelling. However, due to the multiscale complexity of the landscape, to limitations related to illumination and atmospheric conditions, bridging the gap between field and satellite observations remains a major challenge.
The Remote Sensing Action Group aims at shortening the path between field scientists and the remote sensing community, by increasing the availability of calibration and validation data at the circumpolar scale. The action group will make use of UAV and satellite data collected with different sensors and to improve the data and models that address issues such as: permafrost characteristics, thaw lake dynamics, coastal erosion, vegetation community dynamics and infrastructure. For this, we will collaborate closely with the other T-MOSAiC action groups. |
