Gamma radiation monitoring at the Azores ENA-ARM station (Graciosa Island)

Gamma-ray total counts in counts/minute (cpm), every 15-minutes, from the Gamma Radiation Monitoring campaign at the ENA site (Graciosa, Azores). Data were collected to study the temporal variability of the progeny of the noble gas radon (Rn-222), aiming to examine how it is influenced by meteorological conditions and its association with the atmosphere's ionization and aerosols concentration.
