Abstract

The objectives of this study is to evaluate SPOT/HRV data as acquired during the ADAM project. Between October 200 and July 2001, 39 SPOT/HRV images have been collected. They correspond to SPOT 1, 2 and 4. The consistency between images was analysed over a 10×10 km² area of agricultural crops located near Bucharest in Romania. The day to day signals show significant variations that could not be easily interpreted in terms of the surface characteristics. Artefacts such as residual clouds, view zenith angle, soil moisture or improper atmospheric correction are discussed. Conclusions are drawn on the quality of this time series and possible ways for improvement.
