Meet a young researcher who studies the behaviour of volcanoes worldwide
Researcher Camila Novoa Lizama, of the University of Leeds, recently analysed how the use of Synthetic Aperture Radar (SAR) imagery over the Puyehue Cordón-Caulle Volcanic Complex, in Chile, acquired by ALOS-1, Envisat and the Copernicus Sentinel-1 satellites, helped her team to better comprehend the temporal and spatial behaviour of ground displacements before, during and after the volcano’s last eruption.

ESA's (A)SAR dissemination service enhanced with Envisat ASAR MR L1 data
With integration of four additional Envisat ASAR Level 1 collections, ESA is now providing access to the complete Envisat and ERS (A)SAR imagery data archive via the ESA (A)SAR Online Dissemination service.
Data - Data Description
Envisat ASAR AP Co- and Cross-polar L0 [ASA_APC/APH/APV_0P]
The ASAR Alternating Polarization Mode Level 0 (Co-polar and Cross-polar H and V) products contain time-ordered Annotated Instrument Source Packets (AISPs) corresponding to one of the three possible polarisation combinations: HH & HV, VV & VH and HH & VV, respectively. The echo samples in the AISPs have been compressed to 4 bits/sample using FBAQ. This is a high-rate, narrow swath mode, so data is only acquired for partial orbit segments. There are two co-registered images per acquisition and may be from one of seven different image swaths. The Level 0 product was produced systematically for all data acquired within this mode. Data Size: 56-100 km across track x 100 km along track. There are three AP Mode Level 0 products: ASA_APH_0P: The Cross-polar H Level 0 product corresponds to the polarisation combination HH/HV. ASA_APV_0P: The Cross-polar V Level 0 product corresponds to the polarisation combination VV/VH. ASA_APC_0P: The Co-polar Level 0 product corresponds to the polarisation combination HH/VV= H and H received/V transmit and V received.
