Summary

The main aim of the SIOS InfraNOR project is to successfully operate a multidisciplinary and state-of the-art observational system in Svalbard for marine, terrestrial and atmospherical research. In this subpart we work on upgrade of the existing automatic weather station (AWS) at Verlegenhuken with new sensors and establishment of a new permafrost borehole for long-term monitoring linked to the existing AWS. As part of the SIOS initiated InfraNOR Norwegian Research Council funded infrastructure project we will be improving the atmospheric monitoring and establish a unique borehole for long-term permafrost monitoring in northern Svalbard. The upgrade and permafrost borehole will provide new and more accurate knowledge on radiation, snow cover and permafrost temperatures and will be important for the monitoring of climate change towards the northern regions of Spitsbergen, where we currently have a poor observational base. Below is the details of the planned fieldwork, for which we apply for permits to carry out the planned upgrade and drilling. The AWS at Verlegenhuken has been in operation since 1997. The station provide real-time data, and data transfer and storage takes place through MET Norway operational systems. This secure fast data access for both operational weather forecasting, local rescue services, researchers, tourism and the general public. Network of meteorological/climate observatory stations, supplied with additional equipment addressing the radiation climate, are the backbone of any Earth System observation network. The site at Verlegenhuken is especially well suited for validation of satellite products due to the topography and surroundings, and the data are of great value for atmospheric, coastal/marine and terrestrial science. We will enhance the utilization of the existing infrastructure at Verlegenhuken by upgrading the existing station with additional sensors: short and long wave radiation sensors (pyranometer, pyrgeometer); infrared surface (skin) temperature sensors, snow depth sensors and permafrost temperature sensors down to 30-32m depth. The new sensors: 1) Upward and downward short and long wave radiation (pyranometer, pyrgeometer) 2) Infra Red Surface (skin) temperature 3) Snow depth measurements 4) Permafrost temperature monitoring The sensors 1-3 are planned to be mounted in the existing mast and connected to the existing loggerbox. The sensors are planned mounted in summer 2020 as part of the annual service of weather stations around Svalbard with the Norwegian Coast Guard. Sensor 4 is a thermistorstring (cable diameter 1-2 cm) that monitor ground temperatures in 20-25 levels down to 30-32m depth. The borehole is planned drilled in July 2019 and the thermistorstring is planed installed in summer 2020 together with the sensors in the mast (1-3 above). The borehole will be established 3-8 meter away from the existing AWS.
