    Space helps monitor Earth’s changing biosphere

    Earth’s biosphere is continually changing. Through its pioneering Earth observation missions, ESA is making critical contributions to monitor these changes and their impacts on Earth’s water and carbon cycles.

    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.

    JERS-1 SAR Level 1 Single Look Complex Image

    The JSA_SLC_1P product is comparable to the ESA SLC/IMS images generated for Envisat ASAR and ERS SAR instruments. It is a slant-range projected complex image in zero-Doppler SAR coordinates. The data is sampled in natural units of time in range and along track, with the range pixel spacing corresponding to the reciprocal of the platform ADC rate and the along track spacing to the reciprocal of the PRF. Data is processed to an unweighted Doppler bandwidth of 1000Hz, without sidelobe reduction. The product is suitable for interferometric, calibration and quality analysis applications. Data acquired by ESA ground stations. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.

    JERS-1 SAR Level 1 Precision Image

    The JSA_PRI_1P product is comparable to the ESA PRI/IMP images generated for Envisat ASAR and ERS SAR instruments. It is a ground range projected detected image in zero-Doppler SAR coordinates, with a 12.5 metre pixel spacing. It has four overlapping looks in Doppler covering a total bandwidth of 1000Hz, with each look covering a 300Hz bandwidth. Sidelobe reduction is applied to achieve a nominal PSLR of less than -21dB. The image is not geocoded, and terrain distortion (foreshortening and layover) has not been removed. Data acquired by ESA ground stations. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.
