My general research interests cluster around the application geoinformation technologies for renewable energy potential assessment and environmental monitoring. This includes the use of unmanned aerial vehicles (UAV).
- DESERTEC Global Grid Corridor Feasibility Study
- I am responsible investigator for the DESERTEC Global grid corridor feasibility study, funded by the DESERTEC Foundation. The general framework for this project is provided by the Desertec Global concept. Desertec Global proposes the utilization of solar resources in deserts worldwide for the large scale supply of energy of urbanised regions in the relative vicinity. The backbone of this concept is the construction of a network of CSP power stations in suitable desert locations and to transmit the electric energy via high-voltage-direct current (HVDC) grids to demand centers.
- A central issue within the Desertec Global concept is the feasibility of constructing long-distance HVDC grids that shall link energy resource and energy demand areas. It is unclear how far the implementation of such power lines might be subject to potential technical and socio-economic limitations. Examples for this include terrain morphology, land cover and land use conflicts, and political barriers such as the territories of states that can be expected to be unwilling to co-operate. Only in the EUMENA region, the delineation of potential HVDC lines has been thoroughly investigated, leading to a robust information base for subsequent investment decisions. For other Desertec regions, such rigorous analysis is not available.
- The grid corridor feasibility study at Birkbeck aims to address this shortcoming by carrying out a detailed analysis of potential HVDC corridors by the development and calibration of spatially explicit decision support models for three example regions:
- A) China/Korea/Japan, and
- B) Australia/South-East Asia
- Estimating temporal and spatial variability of inherent optical properties of turbid coastal waters
- My project “Estimating temporal and spatial variability of inherent optical properties of turbid coastal waters” is supported by the Field Spectroscopy Facility of the Natural Environment Research Council with an economic value of £ 47 700.
- Coastal remote sensing has successfully been employed to estimate suspended sediment concentration from space-bore and airborne platforms. The central optical process determining the reflectance of turbid coastal waters is scattering by inorganic suspended particles and the key problem for developing regionally and temporally stable models for the turbid Case 2 waters are variations in particle properties such as size, composition, and mineralogy.
- To date, most applications implicitly assume that the backscattering coefficient remains spatially homogeneous throughout the entire image. Similar assumptions in the temporal domain apply to cases where a timeseries of e.g. tidal dynamics is analysed.
- This project aims to test these assumption by monitoring variations of optical properties over short spatial and temporal units by using the combined deployment of the Wetlabs AC-S underwater spectral absorption and attenuation meter and the HyperOCR radiometer in an intertidal environment.
- Deployment of AC-S/HyperOCR instrument suite at Blackwater Estuary.
- I am interested in supervising in the areas of:
- Energy Geography
- Unmanned Aerial Systems (UAS) as novel research platform for environmental research.
- Aquatic remote sensing and field spectroscopy
- Spatial Decision Support Systems
