Peck or pass? Individual‐level testing of a bird‐repellent seed coating
Pest Management Science, EarlyView.Using sequential unique‐choice tests on an urban population of ringed carrion crows, we show that black pepper oleoresin‐treated maize seeds were avoided, while color alone had no deterrent effect. Abstract Background Carrion crows (Corvus corone) are a major depredating species of spring crops across European agroecosystems, especially during sowing ...

A new lab facility for measuring bidirectional reflectance/emittance distribution functions of soils and canopies [PDF]
Recently, a laboratory measurement facility has been realized for assessing the anisotropic reflectance and emittance behaviour of soils, leaves and small canopies under controlled illumination conditions.

International Journal of Metrology and Quality Engineering, 2016 We present a calibration method of UV index meters under a solar simulator based on a spectroradiometer as reference. The reference spectroradiometer is a double-grating-based type that can measure the erythemal effective irradiance ...

Spectral reflectance of whale skin above the sea surface: a proposed measurement protocol
Remote Sensing in Ecology and Conservation, 2020 Great whales have been detected using very‐high‐resolution satellite imagery, suggesting this technology could be used to monitor whales in remote areas.

SUSPEN intercomparison of ultraviolet spectroradiometers [PDF]
Journal of Geophysical Research: Atmospheres, 2001 Results from an intercomparison campaign of ultraviolet spectroradiometers that was organized at Nea Michaniona, Greece, July 1–13, 1997, are presented. Nineteen instrument systems from 15 different countries took part and provided spectra of global solar UV irradiance for two consecutive days from sunrise to sunset every half hour.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Soil Moisture Active Passive soil moisture retrievals are assimilated into a land surface model and the resulting land reanalysis product is used to initialise the land component of coupled land‐atmosphere experiments. We show that the local impact of land data assimilation on the atmosphere is influenced by two factors: the magnitude by which it ...

Rotating Shadowband Spectroradiometer (RSS) Handbook [PDF]
, 2005 The rotating shawdowband spectroradiometer (RSS) implements the same automated shadowbanding technique used by the multifilter rotating shadowband radiometer (MFRSR), and so it too provides spectrally-resolved, direct-normal, diffuse-horizontal, and total-horizontal irradiances, and can be calibrated in situ via Langley regression.
