At: VAO Symposium ; Bolzano ; 28.3.2017 - 30.3.2017 ; Multispectral sensors at medium resolution are characterized by large coverage and frequent revisit times and are useful to describe features of the land, cryosphere and atmosphere that can be used for studies of status and trends on local to global scales. In this context, the EURAC Institute for Applied Remote Sensing operates a receiving station for satellite data funded by the Province of Bozen/Bolzano and located at Corno del Renon at 2260 m a.s.l.. This site allows having a visibility mask obstacle free including almost all Europe, North Africa and part of Middle East. The antenna with a reflector dish of 5.2 meters in diameter, hosted by the Civil Protection of the Autonomous Province of Bozen/Bolzano, receives data from low orbit satellites transmitting data in X-band and supplies near-real time (NRT) Earth Observation satellite data and products (processed in automatic way) useful in a wide variety of remote sensing applications. The Institute for Applied Remote Sensing manages all the activities related to the ground segment, such as the acquisition, the processing, the archiving and the delivery of the data to the customers. The EURAC antenna has been configured to receive data from the NASA satellites TERRA and AQUA, which carry on board MODIS multispectral sensor, and from Suomi-NPP, equipped with VIIRS multispectral sensor. In order to exploit these data, EURAC applied research has developed several algorithms to create added value products adapted for mountain regions, such as Snow Coverage, Particulate Matter, Leaf Area Index and Normalized Difference Vegetation Index maps over the Alps. Some of these products are the result of a near real time processing chain and they have automatically delivered to the customers such as the Autonomous Province of Bolzano-Civil Protection office and published on the EURAC WebGIS. VIIRS sensor is considered a possible MODIS successor for Earth science data product generation, and will be also on JPSS-1 and JPSS-2 spacecraft missions, therefore it represents a good opportunity to give continuity to the mountain near real time observation. To this aim, the EURAC NRT service is fully operational on MODIS derived products and has been tested with Suomi-NPP, which is instead currently operational only for the RAW Level 0 product, with the possibility to reprocess the whole time series, if needed.
