A semianalytical ocean color inversion algorithm with explicit water column depth and substrate reflectance parameterization [PDF]

Journal of Geophysical Research: Oceans, 2015
AbstractA semianalytical ocean color inversion algorithm was developed for improving retrievals of inherent optical properties (IOPs) in optically shallow waters. In clear, geometrically shallow waters, light reflected off the seafloor can contribute to the water‐leaving radiance signal.

Monitoring Specified Depth Soil Moisture in Field Scale with Ground Penetrating Radar

智慧农业, 2022
Ground-penetrating radar (GPR) is one of the emerging technologies for soil moisture measurement. However, the measurement accuracy is difficult to determine due to some influence factors including radar wave frequency, soil texture type, etc.

Modeling near-field tsunami observations to improve finite-fault slip models for the 11 March 2011 Tohoku earthquake [PDF]

, 2011
The massive tsunami generated by the 11 March 2011 Tohoku earthquake (M_w 9.0) was widely recorded by GPS buoys, wave gauges, and ocean bottom pressure sensors around the source.

On the contribution of the horizontal sea-bed displacements into the tsunami generation process [PDF]

, 2012
The main reason for the generation of tsunamis is the deformation of the bottom of the ocean caused by an underwater earthquake. Usually, only the vertical bottom motion is taken into account while the horizontal co-seismic displacements are neglected in

Research of chlorophyll-a concentration inversion at different depths in Hong Kong offshore waters based on gaussian process regression

IOP Conference Series: Earth and Environmental Science, 2022
Abstract By inverting the changes in chlorophyll-a (chl-a) concentration values, seawater’s pollution level and phytoplankton’s growth can be effectively assessed. In this paper, based on Sentinel-3 OLCI remote sensing image data and actual measured chl-a concentration data, the Gaussian Process Regression (GPR) model was used to invert ...
