[IEEE IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium - Valencia (2018.7.22-2018.7.27)] IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium - Snow Cover Monitoring in Hardangervidda and Sierra Nevada Protected Areas by using Sentinel-L Time Series

摘要： This paper presents first results of a snow cover detection algorithm applied to high resolution Sentine-1 images of two different mountainous protected areas: the Hardangervidda National Park (Norway), and the Sierra Nevada National Park (Spain). The products have been compared with the snow maps generated by using Sentinel-2 acquisitions taken on the same or closest day as the SAR images. This work highlighted issues that require further investigation to improve the snow cover detection in areas characterized by a complex topography, climate and land cover. High quality SAR snow products are very much desirable to be used together with less frequent optical snow products, aiming at a continuous monitoring of protected areas.
