Researchers at Caltech made the animations below which show the seasonal deformation and subsidence of Earth’s surface, respectively, as a result of groundwater extraction and refilling. This occurs when soil and earth layers are compacted and undergo subsidence due to the decrease of upward hydrostatic pressure balancing the weight of the layers.
Surface deformation and subsidence of Earth’s surface is measured using Interferometric Synthetic Aperture Radar (ISAR). ISAR is also used for natural hazard assessment. This includes applications to regions of volcanic, tectonic (e.g. faults and mountains), and construction activities.
The 5th day at the DTU PhD Summer School on Remote Sensing for Wind Energy covered Synthetic Aperture Radar (SAR) remote sensing and power curves.
It concluded with a plenary session.
The fourth day of the DTU PhD Summer School on Remote Sensing for Wind Energy focused on scanning wind lidars, complex terrains, turbulence and wind profiles.
The 3rd day of the DTU PhD Summer School on Remote Sensing for Wind Energy covered wind turbine control using lidars and their accuracy, field work to install and operate a Windcube lidar. It also covered work done with onshore doppler radar to detect and study wind farm wakes.
The day was ended with a dinner at sea onboard the M/S Sagafjord.
Day 2 at the DTU PhD Summer School on Remote Sensing for Wind Energy focuses on Continuous Wave (CW) lidars and Pulsed lidars.
