ENVINET Activities Catalog

ENVINET Activities Catalog

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.

Other catalogs through this service are AMAP, SAON and SEARCH, or refer to the full list of projects/activities.

1. Satellite validation for SAGE III (contribution to VINTERSOL/SOLVE-2)

In december 2001 the SAGE III experiment was successfully launched. The NASA science team of the SAGE III experiment has announced the Koldewey-Station in Ny-Aalesund as "anchor site" for validation, especially for such parameters as optical depth, aerosol extinction profiles and ozone profiles. Because of time coincidence NASA apprechiates support for the prospected validation activities for ENVISAT. This should be also considered as contribution to the NASA accepted project "Ground based Validation of SAGE III by the NDSC Primary Station at Ny-Ålesund, Spitsbergen" for SOLVE-2.

2. SOLVE: SAGE III Ozone Loss and Validation Experiment

In preparation to the launch of the SAGE III experiment in March 2001, NASA and the European Union performed the SOLVE / THESEO-2000 campaign, which had three components: (i) an aircraft campaign using the NASA DC-8 and ER-2 airplanes out of Kiruna/Sweden, (ii) launches of large stratospheric research balloons from Kiruna, (iii) validation excercises for the commissioning phase of SAGE III. The German Arctic research station Koldewey in Ny-Ålesund/Spitsbergen contributes to (i), (ii), and (iii) by performing measurements of stratospheric components like ozone, trace gases, aerosols (PSCs), temperature and winds. The measurement results were transmitted quasi online to the flight planning center in Kiruna, in order to allow a better directing of the air plane flights. In addition the Koldewey-Station has been designated a validation anchor site for the SAGE III validation. The activities are organized within a NASA accepted proposal of ground-based validation support by the NDSC Primary Station at Ny-Ålesund, Spitsbergen and by a SAGE III validation working group for Ny-Ålesund. The main observation periods are from December 1999 to March 2000.
