The AIMS Site Survey

Year: 2023

Type: preprint

Abstract: This paper reports site survey results for the Infrared System for the Accurate Measurement of Solar Magnetic Field, especially in Saishiteng Mountain, Qinghai, China. Since 2017, we have installed weather station, spectrometer for precipitable water vapor (PWV) and S-DIMM and carried out observation on weather elements, precipitable water vapor and daytime seeing condition for more than one year in almost all candidates. At Mt. Saishiteng, the median value of daytime precipitable water vapor is 5.25 mm and its median value in winter season is 2.1 mm. The median value of Fried parameter of daytime seeing observation at Saishiteng Mountain is 3.42 cm. Its solar direct radiation data shows that solar average observable time is 446 minutes per day and premium time is 401 minutes per day in August 2019.
