We computed 43 differential SAR interferograms of ERS data.
DEM is derived from GTOPO30 (low frequency) and stacking of ASTER DEMs.
Tropospheric patterns are estimated and compensated from standard
atmospheric models and meteorological data (cloud dependant fringes).
Low frequency Ionospheric fringes are compensated from TEC maps derived
Residual non tectonic fringes are filtered using an Principal Component
Analysis procedure based
on elastic modeling of the deformation.
Results show strain accumulation of about 3 mm/year.
We finally investigated the potential of MERIS/ASAR data over this area
from real data.
