The Kunlun Station (80°25'02"S, 77°06'59"E, altitude 4087 m) is located in the DA area, on the summit of the east Antarctic Ice Sheet. The ozone monitor is located near the Dome A observatory far away from the living area. Due to the limitation of energy consumption and transportation conditions, the Thermo 49i ozone monitor cannot be used. At this stage, the portable ozone monitor with low energy consumption can only be used. On the 1st of Jan 2016, we deployed a Model 205 Dual Beam Ozone Monitor during the 33rd Chinese National Antarctic Research Expedition. The Model 205 Dual Beam Ozone Monitor makes use of two detection cells to improve precision, baseline stability, and response time. In the dual beam instrument, UV light intensity measurements I0 (ozone-scrubbed air) and I (unscrubbed air) are performed simultaneously. Combined with other improvements, this instrument is the fastest UV-based ozone monitor on the market, with such small size, weight, and power requirements characteristics (Table 1). Fast measurements are particularly desirable for unattended stations, aircraft and balloon measurements, where high spatial resolution is desired. The Model 205 Dual Beam Ozone Monitor is an Environmental Protection Agency (EPA) federal equivalent method (FEM). The Zhongshan Station (69°22'12"S, 76°21'49"E, altitude 18.5 m) is located at the edge of the east Antarctic Ice Sheet, where we installed a UV absorption near-surface ozone analyser (EC9810A) for long-term near-surface ozone monitoring. The observational frequency was 3 min, and the data were transferred in real time to Beijing. Furthermore, to prevent data losses, a CR1000 data logger was used to record the data output in real time. Every three months, the ozone analyser was calibrated using the EC9811 ozone calibrator, and 5 standard concentrations of ozone gas were generated for each calibration. The calibration concentration and measured concentration underwent correlation analysis, and seasonal calibration results were generated every three months. In 2016, 5 calibrations were made, and the appropriate correlation coefficients (r) were all greater than 0.9995. The Amundsen-Scott Station (89°59'51.19 "S, 139°16'22.41" E, altitude 2835 m) is located at the SP and operated by the United States. The near-surface ozone data were downloaded from the Earth System Research Laboratory Global Monitoring Division under the NOAA (https://www.esrl.noaa.gov/gmd/dv/data).
