Abstract

The present study summarizes the results of calibration of Indian Dobson Spectrophotometer No. D112 and D036 during Dobson inter-comparison campaigns, held at Irene, South Africa from 07 – 18 October, 2019 and at Hohenpeissenberg, Germany from 15.07.2020 to 30.07.2020 respectively. In both the international inter-comparison campaigns, European Regional Standard Dobson Spectrophotometer No. D064 had been used as the reference instrument. According to the results of the inter-comparison of Dobson spectrophotometer instrument no. D112 and no. D036 with Regional Standard Dobson Instrument (D064), these instruments are reliable and their measurements are accurate and appropriate for further analysis as their deviations have been found within the acceptable limits i.e. less than - 0.3% for D112 and less than 0.01 for D036 respectively after final calibration.
