Hourly, daily, and monthly mean values of three geomagnetic components and total force were recorded at the MIZUSAWA, ESASHI, and KANOZAN observatories. The dataset contains continuous geomagnetic observations for the year 1997. The data was reported by the organization SCIOPS.
Use Cases
- Analyze temporal patterns in the hourly mean values of geomagnetic components to study diurnal variations.
- Model the relationship between different geomagnetic components (e.g., D, H, Z) and the total force using daily mean values.
- Compare geomagnetic activity levels across the three distinct geographic locations (MIZUSAWA, ESASHI, KANOZAN) using monthly aggregates.
- Validate global geomagnetic field models against ground-truth observations from these specific Japanese stations.
Strengths
- Data from three distinct observatory locations provides spatial comparison points.
- Includes three temporal aggregations: hourly, daily, and monthly mean values.
Limitations
- Dataset is limited to a single calendar year (1997), offering a narrow temporal snapshot.
- The specific row count and data completeness for each station and component are unknown.
- Data is over 25 years old, which may limit relevance for studying recent geomagnetic trends.
