A neutron counter surrounded by a 7,5 cm paraffin wax moderator has recorded cosmic rays at Sanae since May 1971. It follows from the variation in counting rate of this neutron moderated detector (NMD) relative to the variation recorded by the neutron monitor (NM64) during cosmic ray events, that the NMD has a higher sensitivity for low-energy cosmic rays than the NM 64. A differential response function for sea level was derived from aircraft latitude surveys, and used to calculate regression coefficients for the relative variation in counting rates of the NMD and NM64.
