Testing for functional significance of traits: Effect of the light environment in tropical tree saplings

open access: yesEcology and Evolution, 2021
Functional traits have been examined to explain the growth rates of forest communities in different sites. However, weak or nonexistent relations are often found, especially due to the following methodological aspects: 1) lack of an environmental context

Spatial Variability of Shortwave Irradiance for Snowmelt in Forests [PDF]

open access: yes, 2008
The spatial variation of melt energy can influence snow cover depletion rates and in turn be influenced by the spatial variability of shortwave irradiance to snow.

Simultaneous Effect of Temperature and Irradiance on Growth and Okadaic Acid Production from the Marine Dinoflagellate Prorocentrum belizeanum

open access: yesToxins, 2014
Benthic marine dioflagellate microalgae belonging to the genus Prorocentrum are a major source of okadaic acid (OA), OA analogues and polyketides. However, dinoflagellates produce these valuable toxins and bioactives in tiny quantities, and they grow ...

Data-Driven Diagnosis of PV-Connected Batteries: Analysis of Two Years of Observed Irradiance

open access: yesBatteries, 2023
The diagnosis and prognosis of PV-connected batteries are complicated because cells might never experience controlled conditions during operation as both the charge and discharge duty cycles are sporadic.

Estimating spectral irradiance from measurements in seven spectral bands

open access: yes, 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 ...

Utilizing Downwelling Irradiance for Phytoplankton Determination [PDF]

open access: yes, 2012
The downwelling irradiance is rarely utilized to determine optical parameters of a water body since the ever-changing water surface induces strong signal fluctuations in the upper meters of typically 20 to 40 %.
