| 英文摘要 | To support the selection of large optical/infrared telescope sites in western China, long-term monitoring of atmospheric conditions and astronomical seeing has been conducted at the Muztagh-Ata site on the Pamir Plateau since 2017. With the monitoring focus gradually shifting northward, three stations were established: the South point, North-1 point, and North-2 point. The North-1 point, selected as the site for the 1.93-m Muztagh Optical Survey Telescope, has recorded seeing and meteorological parameters since late 2018. In 2023, the North-2 point was established approximately 1.5 km north-east of the North-1 point as a candidate location for a future large-aperture telescope. A 10-m Differential Image Motion Monitor tower and a PC-4A environmental monitoring system were installed to evaluate site quality. This study presents a comparative analysis of data from the North-1 and North-2 points during 2018-2024. The median seeing is 0.89 arcsec at North-1 and 0.78 arcsec at North-2. Both points show clear seasonal and diurnal variations, with winter nights offering optimal observing conditions. On average, about 64 per cent of the nighttime duration per year is suitable for astronomical observations. Nighttime temperature variation is low: 2.03 degrees C at North-1 and 2.10 degrees C at North-2. Median wind speeds are 5-6 m s(-1), with dominant directions between and , contributing to stable airflow. Moderate wind suppresses turbulence, while strong shear and rapid fluctuations degrade image quality. These findings confirm that both the North-1 and North-2 points offer high-quality atmospheric conditions and serve as promising sites for future ground-based optical/infrared telescopes in western China. |
