Airborne Radar and Imaging Spectrometer "AquiferEx" Campaign

Fachgebiet: Fernerkundung, Geländekampagne, Geo-Informationssysteme, Hydrologie, Spektroskopie Gefördert durch: Europäische Raumfahrtbehörde (ESA); Deutsches Zentrum für Luft- und Raumfahrt (DLR) Projektleitung: Prof. Dr. Wolfram Mauser, Scheiber, R. (DLR); Bianchi, R. (ESA); Oppelt, N. Projektwissenschaftler: Laufzeit: 04/2005 - 09/2006

The coarse geographic position of the “AquiferEx” test sites has been already identified within Phase 1 of ESA’s ongoing “Aquifer” project. (for details on “Aquifer” see http://www2.gaf.de/aquifer)

Within “Aquifer” project Areas of Interest (AoI) are defined in Iullemeden (trans-boundary aquifer between Mali, Niger and Nigeria) and SASS (trans-boundary aquifer between Algeria, Tunisia and Libya). Within these AoI Prototype areas (PA) were identified for the generation of remote sensing based products by “Aquifer” project partners and local service providers. Only within these PA, the selection of test sites for the “AquiferEx” airborne campaign has been considered.

ESA, GAF and DLR have agreed on selecting test sites within the SASS prototype areas due to limitations in budget and better local infrastructure, compared to Iullemeden area. The selection of two test sites within two different prototype areas, both in reach from the same airport, determined the choice of Tunisia as the country where the airborne campaign should take place.

As AquiferEx is in support of information product generation based on satellite data, harmonization of satellite data acquisition was performed among Aquifer and AquiferEx project partners to facilitate comparison of information retrieval possibilities for the airborne (high resolution) and space-borne cases. Related spaceborne acquisitions from ENVISAT, ERS, and CHRIS are summarized in the Appendix. 

Data acquired by the AquiferEx airborne campaign will be used by the Aquifer project team for the development and validation of the Aquifer science products (e.g. refined land use map). However, first evaluation of radar data with respect to soil moisture and land use/land cover classification is foreseen within this project.
