Liquid Water Detection under the South Polar Layered Deposits of Mars—A Probabilistic Inversion Approach

Remote Sensing, 2019
Liquid water was present on the surface of Mars in the distant past; part of that water is now in the ground in the form of permafrost and heat from the molten interior of the planet could cause it to melt at depth.

Direct numerical simulation of fog: The sensitivity of a dissipation phase to environmental conditions

, 2019
The sensitivity of fog dissipation to the environmental changes in radiation, liquid-water lapse rate, free tropospheric temperature and relative humidity was studied through numerical experiments designed based on the 2007-Paris Fog observations.

A Review on Bathymetric Inversion Research Based on Deep Learning Models and Remote Sensing Images

Remote Sensing
High-precision inversion of shallow-water depth is crucial to marine resource development, ecological protection, and national defense security. Traditional acoustic detection, LiDAR, and empirical models are limited by high cost, low efficiency, or ...

Mapping the bathymetry of coral islands with the Landsat series: Quantitative evaluation of the consistency and temporal change detection

International Journal of Applied Earth Observations and Geoinformation
Landsat series data (Landsat-5 Thematic Mapper (TM), Landsat-7 Enhanced Thematic Mapper Plus (ETM+), Landsat-8 Operational Land Imager (OLI), and Landsat-9 OLI2) hold significant potential for detecting temporal changes of underwater terrain in optically

Nested Radar Systems for Remote Coastal Observations [PDF]

, 2006
Advances in radar technology now allow the observation of sea surface features at multiple scales, from kilometers, down to metres. In the same manner that nested models are used at different resolutions, nested radars of different frequencies can be ...

Quantifying earthquake-induced bathymetric changes in a tufa lake using high-resolution remote sensing data

International Journal of Applied Earth Observations and Geoinformation
Detecting earthquake-induced bathymetric changes helps to understand the geomorphologic process of tufa lakes. Traditional field measurement methods are difficult for spatially complete and continuous bathymetric mapping.

Band Weight-Optimized BiGRU Model for Large-Area Bathymetry Inversion Using Satellite Images

Journal of Marine Science and Engineering
Currently, using satellite images combined with deep learning models has become an efficient approach for bathymetry inversion. However, only limited bands are usually used for bathymetry inversion in most methods, and they rarely applied for large-area ...
