Abstract. In total, 29 continuous Global Positioning System (GPS) time series data together with from Gravity Recovery and Climate Experiment (GRACE) are analysed to determine the seasonal displacements of surface loadings in North China Plain (NCP). Results show significant variations a strong correlation between GPS GRACE results vertical displacement component; average weighted root-mean-squares (WRMS) reduction 75.6 28.9 % respectively, when atmospheric non-tidal ocean effects were...

Abstract The lunar mascon basins are characterized by high gravity anomalies and thin crust. Study of the density structure beneath can help to understand origin these infer their formation evolution. We propose an efficient forward method based on 3‐D Gauss‐Legendre quadrature (GLQ) Fast Fourier Transforms combined with adaptive discretization strategy ensure accuracy. numerical example demonstrates that computational efficiency is increased about three orders magnitude compared traditional...

Terrestrial water storage (TWS) changes in the Tibetan Plateau (TP) are sensitive indicators for dynamics associated with climate variability. Joint analyses using both GRACE space mission and satellite altimetry data increasingly being used to monitor TWS. The objective of this study is confirm that it possible reliably large lakes based on integrative analysis data. This focuses integrated analysed Lake Qinghai located northeast TP, shows a clear continuous water-level rise since 2004. We...

The inversion of density interfaces using spherical coordinates is usually achieved with techniques developed in the harmonic domain or by applying a rectangular partition surface model cells tesseroid. For irregular data coverage and areas at high latitude, methods under such framework have difficulties utilizing multiresolution models global that can achieve constant resolution. We introduce implementation triangular tessellation as fundamental representation for constructing 3-D...

The A10-022 absolute gravimeter is utilised to measure the gravitational acceleration (g) for first time at 24 sites of six relative calibration baselines (the required standard uncertainty 10 µGal, 1 µGal = × 10−8 m s−2) in China. was firstly used long-term indoor observations and compared with a FG5 gravimeter. analysis data indicates that deviation measurements 4.7 maximum peak-to-peak 16.9 laboratory offset FG5-232 less than 4 µGal. expanded uncertainties are approximately 22.0 combining...

The construction of a high-resolution dynamic water storage model, driven by the mass load huge Three Gorges Reservoir (TGR), is necessary basic data for accurately simulating changes in geophysical field, e.g., gravity, crustal deformation, and stress. However, previously established models cannot meet needs impoundment effects TGR, because these were simplified approximated did not consider variation river boundaries caused level changes. In this study, we combined Gaofen-1 (GF-1)...

Groundwater storage is a spatial and temporal variable that represents an essential part of the global hydrological cycle. Traditionally, many wells (i.e., large number), spatially distributed across basin, are measured annually to monitor changes in groundwater (GW) level. It has been shown invasive measuring water levels agricultural during winter months most representative because normally not use have had sufficient time rebound from seasonal use. However, traditional measurements...

Tobacco filaments are the main source of fuel for cigarettes and playa role in providing smoke flavor. However, when tobacco contains debris, it can pose some health risks. Common debris includes paste, paper shavings, mouthpiece residue. These be inhaled into human body during smoking, causing respiratory discomfort or other problems. Therefore, accurate detection is an important issue that needs to addressed processing process. In order improve accuracy we propose optimized YOLOVX...
