Abstract

This paper analyzed geomagnetic variation of H-component from several geomagnetic stations in Indonesia, that are Kototabang (KTB), Pontianak (PTN), Tanjungsari (TJS), Pare-pare (PRP), Manado (MND), Kupang (KPG), and Pamengpeuk (PMK) during 2014. The study aims to analyze and obtain data set that are suitable for PTN geomagnetic data so that they can fill in the data gaps of PTN. We performed data analysis using standard deviation for PTN and other stations. We found that KPG, MND, PMK, and PRP have smaller deviation standard about 10 nT at geomagnetically quiet conditions. Meanwhile, in disturbed conditions, the maximum standard deviation is 17 nT. Substitution of data for geomagnetic quiet conditions should be done with caution and requires further analysis. The substitution of data for disturbed conditions can be done safely because the maximum standard deviation is smaller than the range of disturbance conversion into K index.

印度尼西亚地区地磁变化h分量分析

本文分析了2014年印尼Kototabang (KTB)、Pontianak (PTN)、Tanjungsari (TJS)、Pare-pare (PRP)、mando (MND)、Kupang (KPG)和Pamengpeuk (PMK)几个地磁站h分量的地磁变化。本研究旨在分析并获得适合PTN地磁数据的数据集，以填补PTN的数据空白。我们对PTN和其他台站的数据进行了标准差分析。我们发现KPG, MND, PMK和PRP在地磁安静条件下的偏差标准较小，约为10 nT。同时，在扰动条件下，最大标准差为17nt。将数据替换为地磁安静条件时应谨慎，需要进一步分析。由于最大标准差小于扰动转换为K指数的范围，因此可以安全地对扰动条件的数据进行替换。
