...  This work presents a systematic investigation of the influence of weather conditions on the calibration errors by using Gaussian fitness, least chi-square linear fitness and wavelet transform to analyze the calibration coefficients from observations of the Chinese Solar Broadband Radio Spectrometers (at frequency bands of 0.0-0.0 GHz, 0.0-0.0 GHz, and 0.0-0.0 GHz) during 0000-0000. We found that calibration coefficients are influenced by the local air temperature. Considering the temperature correction, the calibration error will reduce by about
