Tropical deep convective clouds (DCC) are an excellent invariant target for vicarious calibration of satellite visible (VIS) and near-infrared (NIR) solar bands. The DCC technique (DCCT) is a statistical approach that collectively analyzes all identified DCC pixels on a monthly basis. The DCC reflectance in VIS and NIR spectrums is mainly a function of cloud optical depth, and provides a stable...

a r t i c l e i n f o This study evaluates the performance of ocean color products derived from measurements of the Moderate Resolution Imaging Spectroradiometer (MODIS) on the satellite Aqua using the standard near-infrared (NIR) and the shortwave infrared (SWIR)-based atmospheric correction algorithms in the Chesapeake Bay. The MODIS-Aqua-derived normalized water-leaving radiances, nL w (λ), ...

Five-branched gold nanostars are obtained using Triton X-100 in a seed-growth synthesis. They have the uncommon feature of two intense localized surface plasmon resonances (LSPRs) in the 600-900 and 1100-1600 nm ranges. Both LSPRs convert laser radiation into heat, offering two photothermally active channels in the NIR and SWIR ranges.

Field spectrometer data and leaf area index (LAI) measurements were collected on the same day as the Earth Observing 1 satellite overpass for a study site in the Patagonia region of Argentina. We first simulated the total at-sensor radiances using MODTRAN 4 for atmospheric correction. Then ground spectroradiometric measurements were used to improve the retrieved reflectance for each pixel on th...

Water availability for vegetation use has been associated with the relative amount of water in plant and is a key factor modeling variables related to soil-plant system (e.g., net primary production, drought effects on vegetation). To best our knowledge, integration spectral proxies content (near-infrared (NIR), shortwave-infrared (SWIR) bands) land surface temperature (LST) estimation, not onl...

The Operational Land Imager (OLI) on Landsat-8 represents a generational change from heritage Landsat instruments in its design, while it maintains data continuity with the 40+ year Landsat data archive. It preserves the 30-m ground sample distance, 185-km swath width and VIS/NIR/SWIR spectral bands. Furthermore, data continuity resulted from extensive pre-launch and on-orbit calibration and ch...
