Note
In this page, counting-rate data of cosmic-ray muons are published. There are two types of data corrected and uncorrected for atmospheric pressure effect on muons.
These hourly data are made from 10-minutes data after preprocessing including data cleaning. If you have any request or question for our data, please contact the address placed in the header information of individual data file.
Counting-rate data of Kuwait and Syowa stations are compiled from higher resolution data. Calculation method of them and their statistical errors are described here.
Observation of Syowa Station was started in 2018 (MD1), and in February 2025, the system was expanded (MD2), doubling the effective area.
To improve statistical accuracy, it is recommended to use the sum of the MD1 and MD2 count rate for Syowa MD count rate from February 2025 onward.
