Vegetation as Observed with the AVHRR and the ERS Scatterometer: A Case Study over the Iberian Peninsula
The AVHRR is a spaceborne sensor working in the vizible and infrared part of the electromagnetic spectrum and the ERS Scatterometer is a radial operated in the microwave range (C-Band). Both sensors have acquired long-term global data sets that allow to study and monitor vegetation from a regional to global scale. In this paper, the spatial and temporal patterns of a number of parameters derived from these two sensors are compared. While in many studies the usefulness of the AVHRR to monitor vegetation development over one year has been confirmed, the present study suggests that this is not the case for the ERS Scatterometer. On the other hand, future research may show that the ERS Scatterometer is valuable for the study of general vegetation phenology. Both the ERS Scatterometer and the AVHRR provide information about land cover patterns, and more research is needed to determine if the ERS Scatterometer can provide value added information about vegetation, especially when the much higher spatial resolution of the AVHRR (~1km) compared to the ERS Scatterometer (~50km) is considered.
