Integrated water vapor and temperature profiles at Thule High Arctic Atmospheric Observatory, SOP winter 2018

In the frame of the OASIS-YOPP project measurements of Integrated Water Vapor (IWV) and Temperature Profile (TP) have been carried out at the Thule High Arctic Atmospheric Observatory (THAAO, thuleatmos-it.it/) for the winter Arctic Special Observing Period of the YOPP (February 1st to March 31st 2018). The Observatory is located at South Mountain at 220 m a.s.l. in proximity of the Thule Air Base (76.5 °N, 68.8° W).

IWV and TP are retrieved respectively from the 14 brightness temperatures (BTs) measured by a RPG HATPRO-G2 microwave radiometer (MWR) in the K and the V band (Rose, T., Crewell, S., and Löhnert, U.: A network suitable microwave radiometer for operational monitoring of the cloudy atmosphere, Atmos. Res., 75, 183-200, doi:10.1016/j.atmosres.2004.12.005, 2005). Values of IWV are derived by zenith measurements of BTs sampled at 2 s resolution, while TP are obtained by BTs sampled in the scanning mode with a temporal resolution of 15 minutes.
