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.
