Analysis on Characteristics of Radiosonde Bias Using GPS Precipitable Water Vapor [PDF]

Journal of Astronomy and Space Sciences, 2010
As an observation instrument of the longest record of tropospheric water vapor, radiosonde data provide upper-air pressure (geopotential height), temperature, humidity and wind. However, the data have some well-known elements related to inaccuracy.

Precipitable water vapor (PWV) estimations from the site of the Eastern Anatolia Observatory∗ (DAG), a new astronomical observatory in Turkey

Experimental Astronomy, 2018
We present preliminary statistics on the precipitable water vapor (PWV) content over the Karakaya Hills in Erzurum city, where the largest optical and near-infrared astronomical telescope in Turkey will be operated. Since the observatory will observe in the near-infrared (NIR), it is intended to perform PWV measurements of the atmosphere above the site
