IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Air temperature at approximately 2 m above the ground ($T_{a}$) is one of the most important environmental and biophysical parameters to study various earth surface processes. $T_{a}$ measured from meteorological stations is inadequate to study its spatio-temporal patterns since the stations are unevenly and sparsely distributed. Satellite-derived land

SUTO-Solar Through-Turbulence Open Image Dataset
Sensors, 2022 Imaging through turbulence has been the subject of many research papers in a variety of fields, including defence, astronomy, earth observations, and medicine. The main goal of such research is usually to recover the original, undisturbed image, in which

Revisiting the T2 spectrum imaging inverse problem: Bayesian regularized non-negative least squares
NeuroImage, 2021 Multi-echo T2 magnetic resonance images contain information about the distribution of T2 relaxation times of compartmentalized water, from which we can estimate relevant brain tissue properties such as the myelin water fraction (MWF).

Simultaneous determination of in situ vertical transitions of color, pore-water metals, and visualization of infaunal activity in marine sediments [PDF]
, 2009 The vertical color transition from brown to gray-green in marine sediments is linked to the Fe redox boundary and is commonly used as a proxy for biogeochemical state. We combine time-lapse sediment profile imaging with diffusive gradient thin (DGT) gels
