Assessment of the aerosol optical depths measured by satellite-based passive remote sensors in the Alberta oil sands region [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Several satellite aerosol optical depth (AOD) products are assessed in terms of their data quality in the Alberta oil sands region. The instruments consist of MODIS (Moderate Resolution Imaging Spectroradiometer), POLDER (Polarization and Directionality ...

Radiometric in-situ calibration of satelital sensors of Earth observation using a spectroradiometer [PDF]

open access: yesPublished in Revista Colombiana de F\'isica, Vol. 43, No.1, 2011, 2012
By using the satelital information of Earth observation unloaded by a station constructed in the country and reflectances measurements of the soil, we found the total radiation attenuation of the atmosphere for a small region of the Colombian territory. It was necessary to use the Fourier's theory that describes the ideal filters of signals to find the

3D Printing of Deformable Multicolor Alternating‐Current Electroluminescent Devices Through Rational Design of Functional Inks

open access: yesSmall, EarlyView.
A highly deformable alternating‐current electroluminescent device is fabricated via direct ink writing of UV‐curable functional inks. The rational design of the thiol‐ene emission layer and ionic hydrogel electrodes enables high‐resolution printing of complex 3D architectures.

Assessment of Accuracy of Moderate-Resolution Imaging Spectroradiometer Sea Surface Temperature at High Latitudes Using Saildrone Data

open access: yesRemote Sensing
The infrared (IR) satellite remote sensing of sea surface skin temperature (SSTskin) is challenging in the northern high-latitude region, especially in the Arctic because of its extreme environmental conditions, and thus the accuracy of SSTskin ...

Multi-Temporal Spectral Analysis of Rice Fields in South Korea Using MODIS and RapidEye Satellite Imagery [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
Space-borne remote sensing is an effective and inexpensive way to identify crop fields and detect the crop condition. We examined the multi-temporal spectral characteristics of rice fields in South Korea to detect their phenological development and ...

Efficient Aerosol Retrieval for Multi-angle Imaging SpectroRadiometer (MISR): A Bayesian Approach [PDF]

open access: yesarXiv, 2017
Recent research in Aerosol Optical Depth (AOD) retrieval algorithms for Multi-angle Imaging SpectroRadiometer (MISR) proposed a hierarchical Bayesian model. However the inference algorithm used in their work was Markov Chain Monte Carlo (MCMC), which was reported prohibitively slow. The poor speed of MCMC dramatically limited the production feasibility

Evaluating patterns of plant phenological progression and pronghorn movement behaviors across diverse landscapes Évaluation des modèles de progression phénologique des plantes et des comportements de mouvement des antilopes d'Amérique dans divers paysages

open access: yesWildlife Monographs, EarlyView.
We found variable spatial and temporal patterns and predictability of plant phenological progression across 8 pronghorn ranges in Montana. We sampled potential exposure to phenology values for migrants and residents along spring movement paths and summer ranges and found that within herds and years the resident and migrant movement strategies conferred
