WMO/GAW inter-comparison of Dobson Ozone Spectrophotometer in Tsukuba, Japan-2006 and inter-comparison of National standard 112 with Delhi Dobson 36

Abstract

The WMO/GAW campaign for inter-comparison of Dobson Ozone Spectrophotometer was held from 6 to 24 March 2006 at the Aerological Observatory, Tsukuba, Japan. During the inter-comparison campaign, the Indian standard Dobson Ozone Spectrophotometer no.112 was compared with the regional standard Dobson Ozone Spectrophotometer no.116. The comparisons confirmed that the Indian standard Dobson Ozone Spectrophotometer no.112 was in good state of calibration and the data derived from the instrument was reliable. The results of 112 with 36 are also in good agreement with each other.
