    Description: The Weather Forecast at the Italian base in Antarctica “Mario Zucchelli Station”, is a service conducted by personnel from Aeronautica Militare Italiana (Italian Air Force) and is very important for operational activity during the summer expedition. It allows to manage the base activities in order to use resources in a very safe mode. Currently, weather forecasts, are based on the Global Model of European Centre for Medium Weather Forecast (ECMWF, Reading, UK) data, and on the AMPS forecasts provided by NCAR. Concerning ECMWF data, PNRA staff manages the system architecture from data acquisition directly from Centro Nazionale Meteorologia e Climatologia of Aeronautica Militare (CNMCA, Pratica di Mare, Italy), the italian meteorological service, to data processing and distribution. The final result is the GRADS maps production, utilized by base staff for forecasting activity. During the XXI Antartic expedition the system architecture was changed. It was migrated on Linux-Red Hat platform with the aid of open-source software and it was improved in order to: 1. to supply a more reliable system in term of data distribution and 2. to upgrade the product in the respect of the technical requirements suggested by the meteorological staff.

    Description: During the Antarctic campaign 1989-1990, a NOAA-HRPT receiving station was installed at the Italian Base, Mario Zucchelli Station, at Terra Nova Bay. The receiving station is operational when the base is open, usually from mid-October to mid-February. Three NOAA polar orbiting satellites are normally in operation at the same time, at the present they are NOAA-15, NOAA-17, NOAA-18. During the campaign 1998-1990 was installed a new dual-receiving HRPT station to get also DMSP (Defence Meteorological Satellites Program of USA) satellites and currently we receive three DMSP satellites f-13, f-14 and f-15. At the present about fifty passes per day are acquired and processed each day reaching a total of around 4500 passes per expedition. All data acquired during campaigns are stored on DDS tape, which format is changed during years. Up to now more than 7 TB of data are stored on different media (from 8mm tapes to DDS4 tapes), regarding a period of time from V to XXII expedition. In order to achieve a more flexible and reliable system to access all the above data, in 2005, a process to copy to Hard-Disk storage in RAID mode, has been started. The activity is a work in progress, in the meantime the opportunity to realize a web application to process and distribute data to scientific community has been planned. We created a working prototype system based on a LAMP open source architecture (Linux, Apache, MySQL, PHP) and the TERASCAN software (from SeaSpace Corp.) to process and archive remote sensing data. The demo provides a web form to query the relational database containing all data related to each raw acquired satellite pass and as final result a quicklook of the requested pass is showed. This demo is just a first step of an application that in the future will be able to supply to the user a valid tool to navigate in entire data archive and eventually getting products such AVHRR images, TOVS profile, ARGOS data or extracting the complete satellite pass.

    Description: We have studied the disastrous effects of the tsunami triggered by the earthquake (M 9.0) occurred on March 11th, 2011 offshore the Honshu island (Japan). The tsunami caused a huge amount of casualties and severe damages along the coastline of most of the island. The dataset used is composed of data in the visible and thermal spectral range provided by ASTER sensors, and in the microwave range from the active SAR sensors by ENVISAT mission. The processing and the analysis of this large amount of data from different sensors was performed in order to obtain the tsunami inundation map of the Sendai coastal area. Unsupervised and supervised classification algorithms have been applied to provide land cover change detection maps. The identified classes are: stressed vegetation, infrastructure and structure damage, flooded and debris areas. A maximum value of the inundation, about 6 km, is found in the central portion of the Sendai plain and the distance drops to about 1 km at the edges of the plain. The maximum inundation line has been jointly analyzed with the ASTER DTM providing the run-up, values ranging from a minimum of few meters to a maximum of 35m. We point out that the high-relief and the slope gradient are the main inland factors influencing the inundation distance in the study sector, while the vegetation cover and the coastal strike do not significantly affect run-up and wave inundation.

    Description: Hyperspectral sensors have become a standard technology used in the techniques of observation by satellite and aerial platform for observing the terrestrial ecosystem with particular interest in the detection and identification of minerals, vegetation, materials and artificial environments. The detection of real materials depends on the coverage spectral resolution and signal to noise ratio of the spectrometer itself, as well as the density of the material and the absorption characteristics for the material in the region of wavelength measured. The signal to noise ratio in particular is one of the parameters that need to be estimated to establish the quality of images acquired by these systems. In this contribution a method to estimate the Signal to Noise Ratio (SNR) for unsupervised hyperspectral images has been investigated. The method uses the computation of local means and local standard deviations of small homogeneous blocks in order to define respectively the average signal and the mean noise of the images. If the noise may be considered mainly addictive the local standard deviation may be considered as the mean noise of image. This method uses all the spatial information contained in the image scene giving a representative SNR of entire image. The technique has been engineered in IDL environment and applied to hyperspectral data of HYPER-SIMGA sensor, developed in the frame of AIRFIRE Project for wildfire detection by airborne remote sensing data. The SNR results point out that HYPER-SIMGA SWIR images are quite noisy and the spectral range that has to be taken into account for data analysis is from 1000 to 1700 nm.

    Description: After PREVIEW FP6 Project’s conclusion, the WP30210 within FP7 GMES SAFER (Services and Applications For Emergency Response) Project has the main objective to refine and consolidate the Earthquake & Volcanoes (E&V) services that were just tested in previous activities and to provide operative services to Users, the Civil Protection Authorities. Here we mainly report objectives and results for the specific tasks related to Eruptive volcanic parameters (WP30211). Four specific products related to the volcanic events which will contribute to the monitoring of the phenomena and mitigation of the eruption effects are expected within the end of the Project. They mainly concern: SAR displacement, high temperature events (HTE), Ash detection, SO2 concentration and flux, and Ash dispersion models. In particular, here we mostly focus on the activity performed in the occasion of FP7 GMES SAFER activation during two major volcanic eruptions occurred in 2010. The first activation was for the Eyjafjallajökull eruption occurred in Iceland between April and May 2010, and the second one was solicited in the occasion of the eruption of Mount Merapi (Indonesia) in October-November 2010. Here we present the results of both remote sensing and modeling activities performed during these two events.
