Abstract

Abstract. Measurement of the geomagnetic field in Indonesia is undertaken by the Meteorology, Climatology and Geophysics Agency (BMKG). Routine activities at each observatory include the determination of declination, inclination and total field using absolute and variation measurements. The oldest observatory is Tangerang (TNG), started in 1964, followed by Tuntungan (TUN) in 1980, Tondano (TND) in 1990, Pelabuhan Ratu (PLR) and Kupang (KPG) in 2000 and Jayapura (JAY) in 2012. One of the main obligations of a geomagnetic observatory is to produce final measurements, released as definitive data, for each year and make them widely available both for scientific and non-scientific purposes, for example to the World Data Centre of Geomagnetism (WDC-G). Unfortunately, some Indonesian geomagnetic observatories do not share their data to the WDC and often have difficulty in producing definitive data. In addition, some more basic problems still exist such as low quality data due to man-made or instrumental noise, a lack of data processing knowledge, and limited observer training. In this study, we report on the production of definitive data from Indonesian observatories and some recommendations are provided about how to improve the data quality. These methods and approaches are applicable to other institutes seeking to enhance their data quality and scientific utility for example in main field modelling or space weather monitoring.

印度尼西亚地磁观测站的最终数据制作

摘要印度尼西亚的地磁场测量是由气象、气候学和地球物理局(BMKG)进行的。每个天文台的日常工作包括使用绝对和变化测量来确定赤纬、倾角和总场。最古老的天文台是坦格朗(TNG)，于1964年开始，其次是屯干(TUN)于1980年，东达诺(TND)于1990年，佩拉布汉拉图(PLR)和库邦(KPG)于2000年和查亚普拉(JAY)于2012年。地磁观测站的主要义务之一是每年产生最终测量结果，作为确定数据发布，并使其广泛用于科学和非科学目的，例如提供给世界地磁数据中心(WDC-G)。不幸的是，一些印度尼西亚地磁观测站不向世界数据中心分享它们的数据，而且常常难以产生确定的数据。此外，一些更基本的问题仍然存在，如人为或仪器噪声导致的数据质量低，缺乏数据处理知识，以及有限的观察者训练。在本研究中，我们报告了印度尼西亚天文台的确定数据的产生，并就如何提高数据质量提出了一些建议。这些方法和办法也适用于寻求提高其数据质量和科学效用的其他研究所，例如在主要实地建模或空间天气监测方面。

期刊介绍： Geoscientific Instrumentation, Methods and Data Systems (GI) is an open-access interdisciplinary electronic journal for swift publication of original articles and short communications in the area of geoscientific instruments. It covers three main areas: (i) atmospheric and geospace sciences, (ii) earth science, and (iii) ocean science. A unique feature of the journal is the emphasis on synergy between science and technology that facilitates advances in GI. These advances include but are not limited to the following: concepts, design, and description of instrumentation and data systems; retrieval techniques of scientific products from measurements; calibration and data quality assessment; uncertainty in measurements; newly developed and planned research platforms and community instrumentation capabilities; major national and international field campaigns and observational research programs; new observational strategies to address societal needs in areas such as monitoring climate change and preventing natural disasters; networking of instruments for enhancing high temporal and spatial resolution of observations. GI has an innovative two-stage publication process involving the scientific discussion forum Geoscientific Instrumentation, Methods and Data Systems Discussions (GID), which has been designed to do the following: foster scientific discussion; maximize the effectiveness and transparency of scientific quality assurance; enable rapid publication; make scientific publications freely accessible.
