ENVINET (European network for arctic-alpine multidiciplanary environmental research) is a research infrastructure network focusing on multidisciplinary environmental research in Europe. The network involves representatives from 18 environmental research infrastructures from the European Alps to the Arctic, representatives of their users and representatives from relevant international organizations and networks. The participating infrastructures cover a broad range of environmental sciences primarily within atmospheric physics and chemistry as well as marine and terrestrial biology.
The ENVINET project directory covers data and observation activities at these stations.

The polar ionosphere is sensible to the enhancement of the electromagnetic radiation and energetic particles coming from the Sun expecially around a maximum of solar activity . Some typical phenomena can occur such as, among the others, geomagnetic storms, sub-storms and ionospheric irregularities. In this frame the high latitude ionosphere may become highly turbulent showing the presence of small-scale (from centimetres to meters) structures or irregularities imbedded in the large-scale (tens of kilometers) ambient ionosphere. These irregularities produce short term phase and amplitude fluctuations in the carrier of the radio waves which pass through them. These effects are commonly called Amplitude and Phase Ionospheric Scintillations that can affect the reliability of GPS navigational systems and satellite communications. The goal of this proposal is to contribute to the understanding of the physical mechanisms responsible of the ionospheric scintillations as well as to data collecting for nowcasting/forecasting purposes at high latitude. As the scarceness of polar observations, the specific site near Ny-Ålesund is of particular experimental interest.
Mapping and monitoring of the snow cover with use of satellitte born optical instruments for (1) direct use of observations of climate change and (2) use of observations in climate modelling. Measurements of the snows spectral reflectance and other physical properties.
The project will provide a long-term, pseudo-global validation support to the ENVISAT-1 atmospheric measurements, based on mutually consistent high-quality solar and lunar observations from FTIR spectrometers operated at primary and a number of complementary NDSC stations. The validation is limited to a number of target species, most of which are primary NRT or OL level-2 products of the mission, with focus on NOy components: O3, NO2, NO, N2O, HNO3, HNO4, H2CO, CO and CH4. Synergistic use will be made of column and profile data from MIPAS, GOMOS and SCIAMACHY. The ground network will deliver mean vertical column abundances for all target species with NDSC-type quality, and height profile information for some target gases as secondary products to the PI's home institute, where the correlative analyses with the ENVISAT-1 products will be done. Asynoptic mapping tools will support the validation efforts.
The main goal of this research project is to complete the collection of snow/ice field data and to improve the organization of snow/ice spectral signatures, and structural data, along with ancillary information in the existing archive.
To survey and characterise the occurrence of biogenic reefs of cold-water corals in the Minch: • Conduct side scan sonar survey of ridge feature east of Mingulay. • Ground-truth the sonar results with targeted camera / ROV deployments. • Repeat this survey at other locations to examine how widespread this habitat may be in the Minch. • Sample live coral and rubble zones with minimally invasive video-directed grab sampling. • Report on findings and present summary data in a GIS compatible format (ArcView).
The goals of this experiment are to map out the chemical changes in the free troposphere as the atmosphere transitions from winter to spring. It is hoped to begin to understand the chemical conditions that influence the lifetime of ozone and understand more about the productivity of this region of the atmosphere with respect to the in-situ production of ozone. How the free troposphere responds to changing levels of pollution could be critical to the development of future abatement strategies.

Changes in surface reflection at the arctic tundra at Ny-Ålesund, Svalbard (79 N) were monitored during the melting season 2002 using a low cost multispectral digital camera with spectral channels similar to channels 2, 3, and 4 of the Landsat Thematic Mapper satellite sensor. The camera was placed 474 m above sea level at the Zeppelin Mountain Research Station and was programmed to take an image automatically every day at solar noon. To achieve areal consistency in the images (which is necessary for mapping purposes) the images were geometrically rectified into multispectral digital orthophotos. In contrast to satellite images with high spatial resolution the orthophotos provide data with high spatial and high temporal resolution at low cost. The study area covers approximately 2 km2 and when free of snow, it mainly consists of typical high arctic tundra with patchy vegetation and bare soil in between. The spectral information in the images was used to divide the rectified images into maps representing different surface classes (including three subclasses of snow). By combining classified image data and ground measurements of surface reflectance, a model to produce daily maps of surface albedo was developed. The model takes into account that snow-albedo decreases as the snow pack ages; and that the albedo decreases very rapidly when the snow pack is shallow enough (20-30 cm) to let surface reflectance get influenced by the underlying ground. Maps representing days with no image data (due to bad weather conditions) were derived using interpolation between pixels with equal geographical coordinates. The time series of modeled albedo-maps shows that the time it takes for the albedo to get from 80% to bare ground levels varies from less than 10 days in areas near the coast or in the Ny-Ålesund settlement till more than 70 days in areas with large snow accumulations. For the entire study area the mean length of the 2002 melting period was 28.3 days with a standard deviation of 15.1 days. Finally, the duration of the snowmelt season at a location where it is measured routinely, was calculated to 23 days, which is very close to what is the average for the last two decades.

The German Aerospace Center (DLR) Bi-spectral Infrared Detection (BIRD) small satellite is a technology demonstrator of new infrared push-broom sensors dedicated to recognition and quantitative characterisation of thermal processes on the Earth surface. BIRD was successfully piggy-back launched on October 22, 2001 with an Indian Polar Satellite Launch Vehicle (PSLV-C3) into a circular sun-synchronous orbit with an altitude of 572 km and a North - South local equator crossing time at 10:30 h. Besides cameras working in the visible and near infrared spectral range there are two cameras working in the middle infrared (MIR, 3.4 – 4.2 µm) and in the thermal spectral range (TIR, 8.5 – 9.3 µm) respectively. The objective is to validate these two cameras in cooperation with the Koldewey-Station in Ny-Ålesund. Therefore meteorological and aerological data as well as radiation measuring data will be used.
The study aims to optimise the used of landscape data as satellite images, aerial photos, maps, weather data when assessing conditions contributing to accidental risks. So far the study has focused on slope processes along the railway between Kiruna and Riksgränsen (Norwegian border).
