%X In order to satisfy the requirement of the simultaneous measurements of the radiome- tric calibration, it is necessary to seek a simple, convenient and high accuracy method for measuring the spectral optical depth. Therefore, we had several days measurements by us- ing the Spectroradiometer VF921-256 and the solar radiometer DTF-1 simultaneously in Hefei city. Based on the results comparison, we found 1%~4% difference between them. The difference is not only due to the VF921-256, but may be attributed to the calibration error of DTF-1. It is shown from the fitting of measurements of VF921-256 that the stan- dard deviation is less than 0.03. So that the irradiance-based method of atmospheric opti- cal depth measurements can be used to simultaneously measure the optical depth during the radiometric calibration. Meanwhile, we also retrieved the atmospheric aerosol size dis- tribution, the ozone and water vapor colume content of Hefei city by using optical depth information.
