Abstract Type : Poster Abstract Category : Facilities, Technologies and Data science Abstract : To characterize sites in and around Hanle a DIMM seeing monitor has been installed. To make this seeing monitor completely robotic, few critical environmental parameters such as cloud coverage, rain drop, sky brightness, wind speed, wind direction, temperature and relative humidity (RH) are required. Commercially available Automatic Weather Station (AWS) does not provide two most important parameters which DIMM system requires and they are cloud coverage and the sky-brightness. By making use of a precision sensors of different types, we have designed and developed a customized AWS at Indian Astronomical Observatory (IAO) Hanle, Ladakh. The sensors output have gone through rigorous calibration process and its data quality has also been cross checked. Our customized AWS provide all required environmental parameters to the DIMM system on the real time. Then the DIMM software uses these info to assess the weather condition and on event of cloudy sky, high winds, excessive humidity, and/or precipitation, the system automatically suspends DIMM operations to safeguard sensitive equipment. Once conditions improve, including clear skies and low wind speeds, the AWS autonomously resumes DIMM activities, ensuring minimal downtime and enhancing data collection efficiency without requiring manual intervention. In this paper, we present the technical details of our AWS as well as well some sample data collected using the same. |
