Spectrometer and Radiative Transfer Model Comparison using High Sun In-Situ Observations in Pretoria
There is need for reliable in-situ spectral solar irradiance measurements. For instance, the spectrally resolved irradiance may be used to infer its influence on radiative forcing of climate and inExpand
Solar radiation analysis and regression coefficients for the Vhembe Region, Limpopo Province, South Africa
Given the limited observed and reliable data for solar irradiance in rural parts in South Africa, a correlation equation of the Angstrom-Prescott linear type has been used to estimate the regressionExpand

Optical Detectors for Integration into a Low Cost Radiometric Device for In-Water Applications: HyDROW Performance Test at Loskop Dam
Abstract South Africa's fresh water resources are under threat by Harmful Algal Blooms (HABs). A comprehensive and cost effective method for wide area detection and monitoring of HABs is thereforeExpand
Optical Detectors for Integration into a Low Cost Radiometric Device for In-Water Applications: A Feasibility Study
Higher water temperatures and nutrient loads, along with forecasted climate changes are expected to result in an increase in the frequency and intensity of eutrophication-linked algal bloomsExpand
