8th ATMOSPHERIC SCIENCES SYMPOSIUM, 01 Kasım 2017, (Tam Metin Bildiri)
A new 4-meter class of optical and near infrared astronomical observatory is under construction in the Erzurum province of Turkey. The Eastern Anatolia Observatory (DAG) is expected to become operational at the end of 2020. For this kind of astronomical observatory, atmospheric conditions such as percentage of yearly cloud coverage, amount of atmospheric precipitable water vapor (PWV), wind speed and direction, etc., are vital factors in determining the astronomical quality of the site. We present the first results of atmospheric PWV variations in Erzurum through the 2016 – 2017 seasons estimated by GNSS (Global Navigation Satellite System) communication. PWV measurements showed that the site of the observatory, at an elevation of 3170 meters above sea level, has a rather dry atmosphere and is a favorable place for near infrared observations. Comparison of these preliminary PWV estimations with a few other major observatories in the world shows the relative advantages of the site. Furthermore, we expect that the results of atmospheric PWV gathered from such an high location will be helpful for meteorological studies.
