URBANFLUXES at Rome 2015 Science Symposium on Climate

/in , , , , , /da

GEO-K took part at the Rome 2015 Science Symposium on Climate poster session, on November 19-20, with a contribution to URBANFLUXES project.

The recently launched Horizon 2020 project URBANFLUXES investigates the potential of EO to retrieve urban energy budget components, focusing on the anthropogenic heat flux. The main challenge of this project is the innovative exploitation of the Copernicus Sentinels synergistic observations to estimate local scale spatio-temporal patterns of the anthropogenic heat emission in cities. These EO-based spatially disaggregated estimations contain valuable information for both the urban planning and the Earth System Science community.

 

Urban Imagery for thermal behavior of cities at JURSE 2015

/in , , , , , /da

Earth Observation (EO) systems and the advances in remote sensing technology increase the opportunities for monitoring the thermal behavior of cities.
Several parameters related to the urban climate can be quantified from EO data products, providing valuable support for advanced urban studies and urban climate modeling.
The study has been presented at the last JURSE congress in Lausanne. In this study, remote sensing techniques are applied to derive quantitative information necessary to identify possible zones with homogeneous thermal characteristics (Local Climate Zones LCZ).

Parameters like the pervious and impervious surface fraction, the surface albedo, the building density, the mean building/tree height, and the sky view factor are quantified for a study area in Crete, Greece. The EO products are then used under a methodological framework to map the LCZ.

Individual EO products, as well as the LCZ classification itself, is useful to urban climate modeling and studies to assist in planning and decision making.

Future research includes the investigation of more urban parameters extraction with EO data, with the ultimate goal of developing a methodology adaptable to the Sentinels.
