Space-borne SAR sensors are of special interest for mapping flood extent due to the possibility to acquire images in all weather conditions. In this article we review the SAR part of an operational flood mapping service. An operational service requires fully automatic methods that are able to process any available SAR data in near-real time. Mapping flood… (More)
Fennoscandia is characterized by a large degree of climatic diversity. Vegetation phenology may respond differently to climate change according to the climatic gradients within the region. To map the annual and spatial variability of the start of the growing season (SOS) in Fennoscandia, the twice-monthly GIMMS-NDVI satellite dataset was used. The data set… (More)

The flood detector is capable of detecting the majority of the flooded area. However, there are some undetected flooded areas which exhibit high backscatter caused by double bouncing from flooded vegetation.
