Satellite imager calibration and validation

Author: Vhengani, L ; Lubbe, M ; Griffith, D ; Lysko, M Date: Oct 2010 The success or failure of any earth observation mission depends on the quality of its data. Data quality is assessed by determining the radiometric, spatial, spectral and geometric fidelity of the satellite sensor. The process is termed calval. ... Read more
Solving management problems in water distribution networks: A survey of approaches and mathematical models

Author: Bello, O ; Abu-Mahfouz, Adnan MI ; Haman, Y ; Page, Philip R ; Adedeji, KB ; Piller, O Date: Mar 2019 Modern water distribution networks (WDNs) are complex and difficult to manage due to increased level of urbanization, varying consumer demands, ageing infrastructure, operational costs, and inadequate water resources. The management problems ... Read more
South African initiative for pre-flight radiometric calibration of satellite imagers

Author: Griffith, D ; Lysko, M ; Bezuidenhout, D Date: Jul 2009 Internationally, the remote observation of Earth is rapidly maturing alongside the need for higher accuracy in radiance measurements. Accuracy of, and confidence in Earth radiance measurements is vital for applications such as climate change ... Read more
Study of the optical properties of solid tissue phantoms using single and double integrating sphere systems

Author: Monem, S ; Singh, A ; Karsten, AE ; Amin, R ; Harith, MA Date: Dec 2015 Tissue simulators, the so-called tissue phantoms, have been used to mimic human tissue for spectroscopic applications. Phantoms’ design depends on patterning the optical properties, namely absorption and scattering coefficients which characterize ... Read more
Tuz Gölü site characteristics

Author: Leigh, L ; Helder, D ; Behnert, I ; Deadman, A ; Fox, N ; Leloglu, UM ; Özen, H ; Griffith, D Date: Jul 2011 The Tuz Gölü site does demonstrate some challenges for being used as an absolute calibration site. These include: spatial and temporal variability on the order of +/- 0.02, atmospheric transmittance variability on the order of between 0.52 ... Read more
