Multispectral and InSAR datasets for the Fernandina 2024 eruption, Galápagos Islands

This archive contains remote sensing datasets computed as part of the study Lava Tube System Development Defined by Multispectral Imaging and InSAR: the Case of the 2024 Eruption of Fernandina Volcano (Galápagos), which has been submitted for possible publication in Journal of Geophysical Research - Solid Earth. The following datasets are available: Landsat 8/9 images, cropped on the lava field. Two composite image are given: (1) lava-flow composite image from bands 10, 7 and 6; and (2) true-colours. The images cover a period from Mar. 2024 to Oct. 2024. The archive name is Fernandina2024_lavaflow_Landsat_images.zip. Sentinel-2 images, cropped on the lava field. The composite images are created from SWIR, NIR and Red bands. The images cover a period from Feb. 2024 to Oct. 2024. The archive name is Fernandina2024_lavaflow_Sentinel2_images.zip. Sentinel-1 InSAR coherence images are given in Fernandina2024_lavaflow_Sentinel1_images.zip. In details, the images are Sentinel-1 Ascending (relative orbit: 106) and Sentinel-1 Descending (relative orbit: 128) images between Feb. 2024 and Oct. 2024. The maps of InSAR estimates (displacements, thickness, etc.) performed on the lava field are provided by the file Fernandina2024_lavaflow_Sentinel1_results.zip. The file Fernandina2024_lavaflow_vector.zip includes the vector files used in the study. The file TS_displacement_summit_2024.txt includes the InSAR vertical displacements between Feb. 2024 and Oct. 2024, for a point at the summit of Fernandina. Raster and vector data are given in Geotiff format and shapefile, with CRS codes EPSG:32615 and EPSG:32715. Futher information can be found in the metadata. Coherence images are given in uchar format. Please rescale the pixel values between 0 and 1 before use. The datasets are derived from original satellite imagery as follows: Copernicus Sentinel-1 data are retrieved from ASF DAAC and Copernicus Data Space Ecosystem (2024), processed by ESA. Copernicus Sentinel-2 data are retrieved from Copernicus Data Space Ecosystem (2024), processed by ESA. LandSat-8/9 and ICESAT-2 data are retrieved from USGS Earth Explorer (2024), processed by NASA.
