| Description | The main goal of the presented study was to evaluate spatiotemporal variability of the climate conditions of the coastal ice-free zone of Petuniabukta, north-western branch of Billefjorden, Spitsbergen. Since 2008, several automatic weather stations (AWS) have been operated along the northern coast of Petuniabukta at different altitudes. To examine variation of the local climate conditions the meteorological data from lower (AWS1 – old marine terrace at 15 m a.s.l.) and higher part (AWS4 – mountain ridge of Mumien Peak at 475 m a.s.l.) of the coastal zone were used. Each AWS was equipped with an identical set of sensors to measure air temperature and relative humidity at a height of 2 m, soil temperature and volumetric water content (VWC) at the depths of 5 and 15 cm. Apart from that, an extended monitoring program was carried out at AWS1. It consisted of the measurements of global and reflected shortwave radiations, photosynthetically active radiation, wind speed and direction, air pressure, surface temperature and soil temperature profile up to 150 cm. The wind direction and air temperature at AWS1 were influenced by local orography of the coastal zone of Petuniabukta and location of the glacier valleys – Ragnarbreen, Horbyebreen, and Svenbreen. In the study period, the predominant wind was from the S to SE direction. |
