| contents | Accurate measurements of cosmic ray proton flux are essential for studying the modulation processes of cosmic rays during the solar activity cycle. A proton flux measurement method, based on ground-based neutron monitor (NM) data and deep learning techniques, is presented. After the necessary pre-processing of ground-based NM data using a convolutional neural network (CNN) model, we simulate the relationship between NM observations and proton flux measured by the Alpha Magnetic Spectrometer (AMS). The daily proton flux data, ranging from 1 GV to 100 GV, are obtained for the period from 2011 to 2024, showing strong agreement with the observed values. In addition, daily proton flux measurements are provided for periods when AMS data were unavailable due to operational reasons. For the first time, hourly proton fluxes as a function of rigidity are calculated dedicated to the short-time solar activity studies. |
