Photoselective Protective Netting Improves “Honeycrisp” Fruit Quality

Plants, 2020
High temperatures, wind, and excessive sunlight can negatively impact yield and fruit quality in semi-arid apple production regions. Netting was originally designed for hail protection, but it can modify the light spectrum and affect fruit quality. Here,

Spectroradiometer Calibration for Radiance Transfer Measurements

Sensors, 2023
Optical remote sensing and Earth observation instruments rely on precise radiometric calibrations which are generally provided by the broadband emission from large-aperture integrating spheres. The link between the integrating sphere radiance and an SI-traceable radiance standard is made by spectroradiometer measurements.
