국제 연구 참여를 위한 돕슨 분광광도계 반출 준비 작업 과정

Abstract

Dobson spectrophotometer is the representative ground-based remote sensing instrument for the continuous monitoring of stratospheric ozone variation. Therefore, Dobson spectrophotometer has been significantly considered as a standard instrument in the Global Atmospheric Watch programme (GAW) of World Meteorological Organization (WMO), meaning that the participation to the international collaboration is quite important. Yonsei University in Seoul (37.34N, 126.95E) has been operating a Dobson spectrophotometer No. 124, as one of the GAW stations since the year 1984. Due to the longterm usage (~40 years) it is very important to maintain the performance of Dobson spectrophotometer for a sustainable and reliable data production. GAW officially recommends from their report (#183) to calibrate Dobson instrument regularly by comparing to the primary or regional standard Dobson spectrophotometers. For this calibration purpose, Dobson instrument at Yonsei university was shipped to the NOAA at Boulder, Colorado, USA in June 2024. This paper is the technical report to include all detailed processes about the preparation of this shipping, such as parts separation, packing, and final shipping. We believe that this report can provide a number of useful information in detail to users of Dobson spectrometer or other ground-based instrument who needs the instrument shipping for the international collaboration.
