New spectral functions of the near-ground albedo derived from aircraft diffraction spectrometer observations [PDF]

, 2014
The airborne spectral observations of the upward and downward irradiances are revisited to investigate the dependence of the near-ground albedo as a function of wavelength in the entire solar spectrum for different surfaces (sand, water, snow) and under ...

Calibration of a single‐diode performance model without a short‐circuit temperature coefficient

Energy Science & Engineering, 2018
We calibrate the seven parameters of a single‐diode model (SDM) for photovoltaic device performance using current‐voltage (I‐V) curves measured under controlled laboratory conditions over a matrix of nominal temperature and irradiance combinations.

Estimating PV Module Performance over Large Geographical Regions: The Role of Irradiance, Air Temperature, Wind Speed and Solar Spectrum

Energies, 2015
We present a study of how photovoltaic (PV) module performance varies on continental scale. Mathematical models have been used to take into account shallow-angle reflectivity, spectral sensitivity, dependence of module efficiency on irradiance and module

Spectral evidence for irradiated halite on Mars

Scientific Reports
AbstractThe proposed chloride salt-bearing deposits on Mars have an enigmatic composition due to the absence of distinct spectral absorptions for the unique mineral at all wavelengths investigated. We report on analyses of remote visible-wavelength spectroscopic observations that exhibit properties indicative of the mineral halite (NaCl) when ...

Extreme ultraviolet solar irradiance during the rising phase of solar cycle 24 observed by PROBA2/LYRA

Journal of Space Weather and Space Climate, 2012
The Large-Yield Radiometer (LYRA) is a radiometer that has monitored the solar irradiance at high cadence and in four pass bands since January 2010. Both the instrument and its spacecraft, PROBA2 (Project for OnBoard Autonomy), have several innovative ...

Estimating spectral irradiance from measurements in seven spectral bands

, 2003
Accurate measurement and characterisation of fluctuations in the irradiance environment is important for many areas of optical remote sensing. This paper reports a method of estimating spectral irradiance over the VNIR region (400 - 1100nm) from the ...
