Connecting the signals of vegetative and reproductive cycles plants using large-scale phenological techniques is not always an easy task, this complexity increases considerably when analysing plant life cycle in grasses, due to ubiquity diversity taxonomic family. This work integrates remote sensing (NDVI from satellite data greenness near-surface imagery) biological-based (airborne pollen moni...

Researchers seek to identify dry lake bed deposits on Mars, if present. The Global Surveyor TES and Mars Odyssey THEMIS are primary tools in this search. However, there are no published thermal infrared spectrometer (hyperspectral) airborne studies of a dry lake bed. Here we present the first such study and the impacts on TES/THEMIS interpretations. This research addresses a looming gap in the ...

A major goal of current research is to address temporal climatic variations that are related to CO2 emissions. A significant portion of these emissions are due to forest destruction and the resulting conversion of biomass to CO2. As 30% of the earth’s landmass is forest-covered, it is important to understand the biomass content with better estimates than are currently available. This research h...

Environmental regulations have greatly improved air and water quality, especially in areas that were dirtiest before regulation. Reducing airborne particulates is especially beneficial, saving thousands of lives and preventing millions of illnesses each year. The potential health benefits may be even greater in developing countries, where pollution levels are high. Proposed reductions in greenh...

Global environmental change has increased forest vulnerability to the occurrence of interacting disturbances, including wildfires and invasive diseases. Mapping post-fire burn severity in a disease-affected forest often faces challenges because burned and infested trees may exhibit a high similarity in spectral reflectance. In this study, we combined (preand post-fire) Landsat imagery and (post...

Particles from channelled emissions of a battery recycling facility were size-segregated and investigated to correlate their speciation and morphology with their transfer towards lettuce. Microculture experiments carried out with various calcareous soils spiked with micronic and sub-micronic particles (1650+/-20mg Pb kg(-1)) highlighted a greater transfer in soils mixed with the finest particle...
