Abstract

Surface atmospheric electric field (AEF) measurements were conducted using a Kelvin water dropper equalizer by the Japan Meteorological Agency's geomagnetic observatory at Kakioka, Ibaraki Prefecture, Japan, from 1929 to February 28, 2021. To obtain AEF data successive to the water dropper measurement, we independently installed the field mills at Kakioka. In this present study, we estimated the calibration coefficients based on comparisons between the water dropper and the field mills through parallel observations over 3 days. The results revealed that the new observations could be regarded as continuous data. Our new data from the field mills in this study have begun the process of being distributed in GLObal Coordination of Atmospheric Electricity Measurements (GloCAEM) as both archived and real-time data in 1 min and 1 s samplings.

日本垣冈长期水滴电位均衡器停止使用后继续进行大气电场测量

从 1929 年到 2021 年 2 月 28 日，日本茨城县垣冈市的日本气象厅地磁观测站使用开尔文水滴均衡器进行了地表大气电场（AEF）测量。为了获得与水滴测量相继的 AEF 数据，我们在垣冈独立安装了野外磨坊。在本研究中，我们通过 3 天的并行观测，根据水滴仪和实地碾磨仪之间的比较估算了校准系数。结果显示，新的观测数据可视为连续数据。我们在本研究中从野外磨坊获得的新数据已开始在全球大气电能测量协调组织（GloCAEM）中以 1 分钟和 1 秒采样的存档数据和实时数据的形式发布。

期刊介绍： Geoscience Data Journal provides an Open Access platform where scientific data can be formally published, in a way that includes scientific peer-review. Thus the dataset creator attains full credit for their efforts, while also improving the scientific record, providing version control for the community and allowing major datasets to be fully described, cited and discovered. An online-only journal, GDJ publishes short data papers cross-linked to – and citing – datasets that have been deposited in approved data centres and awarded DOIs. The journal will also accept articles on data services, and articles which support and inform data publishing best practices. Data is at the heart of science and scientific endeavour. The curation of data and the science associated with it is as important as ever in our understanding of the changing earth system and thereby enabling us to make future predictions. Geoscience Data Journal is working with recognised Data Centres across the globe to develop the future strategy for data publication, the recognition of the value of data and the communication and exploitation of data to the wider science and stakeholder communities.
