What was the purpose of SPARC?

ESA SPectra bARrax Campaign (SPARC) took place in Barrax (Spain) during 12-14 July 2003. This activity was part of the preparatory study for a proposed ESA Earth Explorer mission called SPECTRA (Surface Processes and Ecosystem Changes Through Response Analysis). For this reason the campaign was called SPARC-2004 (SPECTRA Barrax Campaign-2004).

SPARC-2004 researchers wished to simulate SPECTRA's retrieval of biophysical information and the data processing needed to carry out geometric and atmospheric corrections of raw results. With no SPECTRA in orbit they turned to its closest equivalent, ESA's technology demonstrator turned Earth Observation mission PROBA.

SPARC-2004 campaign objective was to collect a CHRIS/PROBA reference dataset for SPECTRA-related studies, with the corresponding associated atmospheric data, surface radiometric data and measured soil/vegetation properties to serve as a validation dataset.
