Our findings reveal a weak but robust linkage between the dominant patterns in both regions. Specifically, an opposite-phase temperature anomaly in NA occurs about 1 week after a Eurasian temperature anomaly, influenced by wave propagation in both the troposphere and stratosphere. Conversely, a same-phase temperature anomaly appears over central Eurasia approximately 1 week after a North American temperature anomaly, primarily driven by a Scandinavian-like pattern in the troposphere.

This study presents an integrated assessment of groundwater vulnerability to pollution utilizing geoelectrical and hydrogeological indices. Vertical Electrical Sounding (VES) surveys were conducted to delineate subsurface lithological variations, while hydrogeological parameters such as porosity, hydraulic conductivity, permeability, and hydraulic resistance were determined to understand groundwater flow dynamics. The VES results revealed four to five geoelectric layers with varying resistivities, thicknesses, and depths, highlighting the complexity of the subsurface. These layers were classified as lateritic sand, medium-coarse brownish sand, coarse sand, and fine-medium coarse-grained sand. The low resistivity observed in parts of the study area suggests the influence of geological structures such as faults and fractures. Groundwater vulnerability indices including Aquifer Vulnerability Index (AVI), GOD index, and GLSI indexes were computed to assess susceptibility to pollution. Porosity, hydraulic conductivity, permeability, and hydraulic resistance were estimated and their values ranged from 27.04 % to 30.21 %, 0.14 m/s to 0.15 m/s, 1.98 to 2.20, and 93.07 to 665.89 respectively. The AVI classified the study area into high and moderate vulnerability classes, with regions of shallow water table exhibiting higher vulnerability. The GOD and GLSI models categorized the study area into low and moderate vulnerability classes.

Using the Community Earth System Model, we conduct a paleoclimate sensitivity study focused on modifying ice nucleation and cloud phase partitioning schemes. These modifications increase the GMST, with a strong temperature rise in high latitudes and a muted increase in the tropics. These increases are driven by enhanced longwave cloud forcing, resulting from increased ice cloud amounts and cloud water content, and are amplified by water vapor and lapse rate feedbacks in the Arctic.

Both the present-climate distributions had northward and southward predominant values near the shore and offshore, respectively, as a result of the combination of the southerly and northerly waves. Under the RCP8.5 scenario, the distributions shifted southward in the nearshore region, even though the mean wave direction did not change. This occurred because the significant wave height of the southerly waves decreased more than that of the northerly waves under this scenario. In the offshore region, northward longshore sediment transport became predominant because the number of large southerly waves increased. The results obtained using the peak wave directions differed from those obtained using the mean wave directions. There was a significant shift in the distributions to the south, and the bimodal distributions became unimodal.

These fields, generated by currents from spacecraft subsystems, are frequently several times stronger than the ambient magnetic field signals of interest. To mitigate this, strict magnetic cleanliness, long mechanical booms, and at least two magnetometers are typically necessary to eliminate the spacecraft-generated magnetic interference. When two magnetometers are placed collinearly on a boom, gradiometry can be performed by modeling the spacecraft's field as a dipole and subtracting it from the magnetometer measurements. However, this technique requires careful preflight characterization of the spacecraft's magnetic field to determine the dipole coupling coefficients and sufficient boom length. This process is time-intensive, costly, and prone to error due to the changing nature of a spacecraft magnetic field environment in operation. We propose a novel method for in situ calculation of the gradiometric coupling coefficients, called the Reduction Algorithm for Magnetometer Electromagnetic Noise (RAMEN). RAMEN utilizes single-source point analysis and the time-frequency content of the magnetometer signals to identify stray magnetic field signals and calculate the gradiometric coupling coefficients. Through two Monte Carlo simulations, we demonstrate that the RAMEN gradiometry algorithm matches gradiometry with preflight coupling coefficient estimation. Additionally, we apply the RAMEN algorithm to noisy magnetometer data from the Venus Express spacecraft to demonstrate its use. The RAMEN method enhances the fidelity of spaceborne magnetic field observations using gradiometry and reduces the burden of arduous preflight spacecraft magnetic characterization.</p>","PeriodicalId":54286,"journal":{"name":"Earth and Space Science","volume":"12 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2024EA003914","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
