Horizontal Pressure Gradient Parameterization for One‐Dimensional Lake Models [PDF]
Journal of Advances in Modeling Earth Systems, 2020 This work presents a new method for closure of horizontally averaged 1‐D thermohydrodynamic equations in an enclosed reservoir by parameterizing the horizontal pressure gradient usually omitted in 1‐D lake models. Horizontal pressure gradient is computed

Tropospheric Second-Order Horizontal Gradient Modeling for GNSS PPP
Remote Sensing, 2022 The asymmetric delay has a considerable impact on Global Navigation Satellite Systems (GNSS) Positioning, Navigation and Timing (PNT) applications. In GNSS analyses, the impacts of the asymmetric delay are commonly compensated by using the classical ...

Minerals (Basel, Switzerland), 2023 Detecting the boundaries of geologic structures is one of the main tasks in interpreting gravity anomalies. Many methods based on the derivatives of gravity anomalies have been introduced to map the source boundaries. The drawbacks of traditional methods

Langmuir turbulence in horizontal salinity gradient
Ocean Modelling, 2018 Abstract Langmuir circulation (LC) is believed to be one of the leading causes of turbulent mixing in the upper ocean. Large eddy simulation (LES) models that solve the Craik–Leibovich equations are used to study LC in the upper ocean, yielding new insights that could not be obtained from field observations or turbulent closure models alone.

Interpretation of magnetic anomalies using the horizontal gradient analytic signal
Annals of Geophysics, 2001 In recent years the analytic signal method has been of great utility in the interpretation of potential field data. The amplitude of the 3D analytic signal of magnetic data yields information on the location of the edges of the sources in both the ...

Detecting horizontal gradient of sound speed in ocean [PDF]
Earth, Planets and Space, 2007 Abstract We propose a new approach to monitor the horizontal gradient of sound speed in ocean for its correction on seafloor positioning using the GPS/acoustic technique. The new method requires five seafloor transponders to solve five parameters: δx, horizontal position of a transponder array; δt, a common delay in traveltimes due to the ...
