This research is aimed to find the effect of sunspots on the variations of air temperature and relative humidity (RH) in Medan City. This research used the daily average of air temperature and RH data from 1985 – 2014 at Kualanamu Meteorological Station which was obtained from BMKG. Meanwhile, the daily sunspot number data within the same year period was obtained from the Solar Influences Data Analysis Center (SIDC) The Royal Observatory of Belgium (RWC). The method that was used in this study is a statistical method. The results of the study show that the coefficient of determination R² between the sunspot number and the parameters of air temperature and RH are 0.9 and 2.2, respectively. Meanwhile, the correlation coefficient between sunspot number and the parameters of air temperature and RH is -0.058 and 0.038, respectively. All variables showed p-value <0.05 which means statistically significant. Thus, the increase in the number of sunspots has significant effects on decreasing air temperature and increasing RH in Medan City.","PeriodicalId":32347,"journal":{"name":"Jurnal Meteorologi dan Geofisika","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91337820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its size and its light absorption ability, black carbon is known to have bad impacts on the climate. This study aims to analyse the effect of forest fires that happened in Riau province, Indonesia in September 2019 towards the production of black carbon, as well as to estimate backward air movement trajectory in order to confirm the air mass sources of the black carbon. The data of black carbon concentration used in this study is an hourly temporal data of MERRA-2 with a spatial resolution of 0.5° × 0.625°, while the trajectory calculation uses the HYSPLIT trajectory model. Linear regression of this study has an r value of 0.78 which shows that there is a positive correlation between black carbon concentration and number of hotspots. The range of BC concentrations were 2–11 × 10-9 kg.m-3 with higher concentration occurred during 9–23 September 2019 where it was affected by the south-easterly wind from Jambi and South Sumatera.","PeriodicalId":32347,"journal":{"name":"Jurnal Meteorologi dan Geofisika","volume":"313 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74403627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The estimated value of deformation based on point-wise GPS and InSAR data with a better spatial resolution must be defined in a reference frame system that reflects the phenomenon of deformation of the real physical world, e.g., orthometric height for the vertical component. Therefore, this study aims to provide alternative DEM models based on a suitable combination between the Global Geopotential Model of Earth Geopotential Model 2008 (EGM2008) and global terrain models, providing position changes with respect to the orthometric height. The alternative DEM models are (i) the global elevation model of ETOPO1 (DEM1), (ii) the modified global elevation model of SRTM30_PLUS (DEM2), and (iii) the regional elevation model of DEMNAS (DEM3). These alternative models comply with each other for the land areas with mean difference values lower than 1 meter. While for the ocean areas, we found that DEM1 and DEM2 have apparent differences due to the different types of data used. However, a similar assessment could not be performed for DEM3 as it only covers the land areas. Additionally, we compared the orthometric height from these terrain models with leveling observations for the coinciding locations. DEM3 achieves the highest accuracy with the estimated standard deviation of 11.2745 meters and is followed by DEM2 and DEM1 with the respective standard deviation of 29.4498 and 37.6872 meters. We found that these models can be used as a starting position determination for horizontal and vertical deformation analysis.","PeriodicalId":32347,"journal":{"name":"Jurnal Meteorologi dan Geofisika","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88508222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sementara itu sebanyak 37 kejadian data gempa bumi (Mw > 5,5) di wilayah Mentawai yang berasal dari USGS digunakan untuk mengkaji anomali foF2 terhadap kejadian gempa bumi selama 14 hari sebelum gempa bumi terjadi. Hasil pengamatan secara umum memperlihatkan terdapat anomali foF2 pada selang 14 hari sebelum terjadinya gempa bumi. Kemunculan foF2 tersebut dapat diduga sebagai indikasi sebagai aktivitas pre-seismic dalam kulit bumi pada 37 kejadian gempa bumi di wilayah Mentawai, meskipun kadang-kadang aktivitas geomagnet dan aktivitas matahari terlihat berpengaruh anomali foF2. Oleh karena itu diperlukan kajian lanjutan untuk menguji korelasi antara anomali foF2 dan kejadian gempa bumi secara statistik.","PeriodicalId":32347,"journal":{"name":"Jurnal Meteorologi dan Geofisika","volume":"103 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80304717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
