Binchuan atmospheric electric field observation

Atmospheric electric field is measured in the town Binchuan (25°50’N, 100°34’E, 1438.7m asl) of Dali city, Yunnan, China with the purpose of understanding the variation of fair-weather atmospheric electric field. The atmospheric electric field is measured using DNDY electric field mill from 2017.6.14 to 2020.12.1. The atmospheric electric field data for each year during the observation period are given in '.csv' form. First column is 'Datetime' and second is 'Ez' (kV/m).Detail information of the data:Time Resolution: 1 secondResolution: 5 V/mLower limit: -50 kV/mUpper limit: +50 kV/mError: ±5%*We also provide data with time resolution of 1 minute. Files name are year_minute.
