EnMAP is a hyperspectral imager covering the 400 – 2450 nm region with about 200 spectral channels. The spatial resolution is 30 m and the nadir swath width is 30 km with an off-nadir across-track tilt capability of 30°. The instrument consists of two spectrometer units (VNIR and SWIR). Due to the prism design the channel sampling distance varies from about 5 nm (blue region) to 12 nm (SWIR). E...

Climate change has a significant impact on winter wheat (Triticum aestivum L.) cultivation due to the occurrence of various environmental stress parameters. It destabilizes production mainly through abiotic stresses (heat waves, drought, floods, frost, salinity, and nutrient deficiency) improved conditions for pest disease development infestation as biotic The these parameters can be reduced by...

Although many Soil Spectral Libraries (SSLs) have been created globally, these libraries still not operationalized for end-users. To address this limitation, study an online Brazilian Service (BraSpecS). The system was based on the Library (BSSL) with samples collected in Visible–Near–Short-wave infrared (vis–NIR–SWIR) and Mid-infrared (MIR) ranges. interactive platform allows users to find spe...

Ground bearing capacity has become a relevant concept for site-specific management that aims to protect soil from the compaction and the rutting produced by the indiscriminate use of agricultural and forestry machines. Nevertheless, commonly known techniques for its estimation are cumbersome and time-consuming. In order to alleviate these difficulties, this paper introduces an innovative sensor...

Spectrometer calibration and measurements of spectral radiance are often required when performing ground, aerial, and space measurements. While calibrating a spectrometer in the field using an integrating sphere is practically unachievable, calibration against a quartz halogen (QH) lamp is a quite easy and feasible option. We describe a calibration protocol whereby a professional QH lamp, opera...

Supernova (SN) 2006gy was a hydrogen-rich core-collapse SN that remains one of the most luminous optical supernovae ever observed. The total energy budget (> 2×10 erg radiated in the optical alone) poses many challenges for standard SN theory. We present new ground-based near-infrared (NIR) observations of SN 2006gy, as well as a single epoch of Hubble Space Telescope (HST) imaging obtained mor...

The feasibility of using visible/near-infrared spectroscopy (vis/NIR) to segregate broiler breast fillets by water-holding capacity (WHC) was determined. Broiler breast fillets (n = 72) were selected from a commercial deboning line based on visual color assessment. Meat color (L*a*b*), pH (2 and 24 h), drip loss, and salt-induced water uptake were measured. Reflectance measurements were recorde...
