NASA study points to infrared-herring in apparent Amazon green-upfor the past eight years scientists have been working to make sense of why some satellite data seemed to show the Amazon rain forest greening-up during the region's dry season each year from June to October.
--but see a large amount of near-infrared light which plants primarily reflect. Scientists use the ratio of red and near-infrared light as a measure of vegetation greenness.
Numerous hypotheses have been put forward to explain why Amazon forests appear greener in MODIS data as the dry season progresses.
Perhaps young leaves known to reflect more near-infrared light replace old leaves? Or possibly trees add more leaves to capture sunlight in the dry season
or reflectance properties have distinct fingerprints in MODIS and GLAS data. Only one of the hypothesized mechanisms for the green-up changes in sun-sensor geometry was consistent with the satellite observations.
We think we have uncovered the mechanism for the appearance of seasonal greening of Amazon forests--shadowing within the canopy that changes the amount of near-infrared light observed by MODIS Morton said.
At this point the forest canopy is shadow-free highly reflective in the infrared and therefore very green according to some satellite vegetation indices.
The research was carried out in the context of the Integrated Project Visions of land use transitions in Europe (VOLANTE) and supported by the European commission and the Einstein Foundation Berlin.

I in Morocco have calculated that hairs that reflect infrared light may contribute significant insulating power to the exceptionally warm winter coats of polar bears and other animals.

All together the model suggests that the repeated backscattering of infrared light between radiative shields like individual hairs
With the right structure fur and feathers can generate efficient thermal insulation in the far infrared range
The idea is to multiply the interaction of electromagnetic waves with grey bodies--reflecting bodies like metals with very low emissivity
The QCL emits light from the mid-to far-infrared portion of the spectrum. That allows for far better detection of gases than more common lasers that operate in the near-infrared.
The technique called quartz-enhanced photoacoustic absorption spectroscopy (QEPAS) invented at Rice by Tittel Professor Robert Curl
The laser beam is focused between the two prongs of the quartz tuning fork. When light at a specific wavelength is absorbed by the gas of interest localized heating of the molecules leads to a temperature
With the help of real-time X-ray diffraction at the EDDI beamline of BESSY II HZB physicists around Roland Mainz and Thomas Unold could now observe how a phase transition from the metastable wurtzite phase to the stable kesterite phase leads
The HZB physicists have developed a model which can explain these findings. By means of numerical model calculations they demonstrated the accordance of the model with the measured data.
Small seemingly trivial changes in environmental conditions can generate dramatic shifts in the underlying dynamics of the disease the researchers wrote.
