The gravity observations covered all the main islands of Indonesia. This paper presents a state-of-the-art for gravity anomalies derivation using airborne gravity mission in Java, Indonesia. The common gravity corrections for deriving the scalar free-air gravity anomalies along the flight trajectory had been estimated using GNSS-derived positions. The corrected data were then filtered using the FIR method in which the cut-off frequency had been predetermined by considering aircraft altitude, geological setting, and instrument’s accuracy. To assess the airborne gravity results, we compared them with the upward continued terrestrial gravity measurements. In addition, we performed crossover analysis and adjusted the estimated biases to the airborne gravity measurements. The accuracy of adjusted airborne gravity anomaly was estimated to 3.37 mGal. In conclusion, the airborne gravity mission provided valuable data needed for further geodesy and geophysics applications","PeriodicalId":22259,"journal":{"name":"Terrestrial, Atmospheric and Oceanic Sciences","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69524222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seismic data transverse to wedge-top zone show the asymmetric and symmetric folds, along with blind thrusts and back thrusts. Seis-mic data parallel to the axis of the wedge-top zone show the volcanic features of poor stratified reflectors, forced fold and intrusive step of volcanic sills along and away from dominating normal fault structures. Since the volcanic extrusions and normal faults are probably associated events, we suggest that post-collisional extensional volcanism northern offshore Taiwan was probably formed along inherited primary and secondary fault structures. The wedge-top zone was formed at frontal part of the early Taiwan orogenic wedge in Late Miocene. Subsequent change of regional stress from convergence to extension led to the mountain collapse as well as primary and secondary normal faults. Thus, these post-collisional normal faults are mechanically weak, probably capable of providing pathways for the Pleistocene-present vol-canisms northern offshore Taiwan. The facilitation of post-collisional fault structures as transportation routes for deep material to migrate along may be important for the formation of the Quaternary volcanism extrusions northern offshore Taiwan.","PeriodicalId":22259,"journal":{"name":"Terrestrial, Atmospheric and Oceanic Sciences","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69525227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ventilation effect could accelerate the heat and mass transfer rates between vapor and falling hydrometeors. It causes the falling hydrometeors to grow (in a supersaturated environment) and dissipate (in a subsaturated environment) faster than the stationary ones. The parameterizations of the ventilation effect on hydrometeors in a cloud model is critical as it could dramatically alter the structure and the lifespan of the simulated storm. Enhancing the ventilation coefficients of falling hydrometeors leads to a longer-lived storm featured by apparent storm splitting. The temporal evolution of hail density fluctuates greater than the default case (the control case) indicating both stronger deposition and sublimation in hail microphysical processes. However, both rainfall and hailfall become less intense than the control run. In contrast, reducing the ventilation effect causes moderate evaporation of raindrops as they fall through subsaturated air. Consequently, the concentration and precipitation rate of raindrops increase near the surface. Strong downdraft accompanying the heavy rainfall cuts off the low-level inflow of unstable moist air into the storm and results in early dissipation of the storm.","PeriodicalId":22259,"journal":{"name":"Terrestrial, Atmospheric and Oceanic Sciences","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69524186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
