The primary processing of the neutron monitor data includes all the necessary actions and procedures that each cosmic ray station follows in order to provide the worldwide neutron monitor network with good quality data. One of the main corrections of the primary data is the pressure correction due to the barometric effect. The barometric effect induces variations to the measured data of the neutron monitors which are related to the variations of the local atmospheric pressure of the stations. This correction requires the definition of the barometric coefficient which is calculated experimentally. The accurate calculation of the coefficient is a prerequisite for the quality of the data. This paper presents the implementation of an online tool which calculates the barometric coefficient of a cosmic ray station, by taking advantage of the fact that most stations publish their data on the Neutron Monitor Data Base.
► The main correction of the primary cosmic ray data is the pressure one due to the barometric effect. ► An online tool that calculates the barometric coefficient for the neutron monitors is described. ► This tool uses the High resolution real-time Neutron Monitor database-NMDB. ► Each station can check if the barometric coefficient used for the data processing is correct. ► The use of a reference station leads to satisfactory results even in the active cosmic ray periods.
