Find research datasets worth reusing

Nearly three centuries of Lava Flow Subsidence at1 Timanfaya, Lanzarote

<p>The following datasets are available for each InSAR dataset - Envisat and Sentinel-1, covering the island of Lanzarote between 2004/01/17 -2010/01/30 and 2016/09/14-2020/06/25 respectively:</p> <p><br> Line of Sight (LOS) velocities<br> LOS velocity standard deviations<br> LOS displacement time series<br> Vertical velocities<br> Vertical velocity standard deviations&nbsp;<br> East-West velocities<br> East-West velocity standard deviations</p> <p>The velocities and standard deviations are all geocoded (latitude/longitude in decimal degrees) geotiff files in mm/yr at 90 m resolution for Envisat and 30 m resolution for Sentinel-1. Negative values in&nbsp;the LOS data&nbsp;represent movement away from the satellite; in the vertical data represent subsidence; and in the East-West data represent westward&nbsp;movement. The velocities were calculated from the displacement time series as a least squares inversion and the standard deviations were calculated within LiCSBAS using a percentile bootstrap method.&nbsp;</p> <p>The Sentinel-1 time series is given as a 3D matrix (lon&nbsp;x lat&nbsp;x dates) within a .h5 file where each slice is the cumulative displacement (mm) in a&nbsp;lon lat grid format for each epoch date. The latitude and longitude are then given as separate vectors within the .h5 file.</p> <p>The Envisat time series&nbsp;is given as a .dat file where the first two columns are&nbsp;longitude and latitude. The remaining columns are the cumulative displacement (mm) for each epoch date.</p> <p>The epoch dates for both are given as separate text files and are given in the format YYYYMMDD.</p>
