Calibration of the Mengcheng Solar Radio Spectrometer
Abstract
Observations of solar radio bursts are one of the most important tools to study solar activities. Based on the analysis of the Mengcheng Solar Radio Spectrometer observations of an M2.9 class flare occurred on 2015 August 27, we find that the classical calibration method does not give satisfactory results, due to the influence of the electronic apparatuses of the instrument. By using the X-ray and radio data of Geostationary Operational Environmental Satellites (GOES), and Nobeyama Radio Polarimeter (NoRP)/Nobeyama Radioheliograph (NoRH), and combined with the relevant radiative mechanisms, the calibration method is improved. Compared to the classical method, the improved calibration method provides better results, which are consistent with the NoRP/NoRH observations and reveal the typical evolution of the radio spectrum for a flare.
