The Collection 6 (C6) MODIS (Moderate Resolution
Imaging Spectroradiometer) land and atmosphere data
sets are scheduled for release in 2014. C6 contains significant
revisions of the calibration approach to account for sensor
aging. This analysis documents the presence of systematic
temporal trends in the visible and near-infrared (500 m)
bands...
Sensor design and mission planning for satellite ocean color measurements requires careful consideration of the signal dynamic range and sensitivity (specifically here signal-to-noise ratio or SNR) so that small changes of ocean properties (e.g., surface chlorophyll-a concentrations or Chl) can be quantified while most measurements are not saturated. Past and...
Seasonality and drought in Amazon rainforests have been controversially discussed in the literature, partially due to a limited ability of current remote sensing techniques to detect its impacts on tropical vegetation. We use a multi-angle remote sensing approach to determine changes in vegetation structure from differences in directional scattering (anisotropy)...
