The principal objective of the Northern Watch Project is to install and test the performance of sensors at the Arctic site near Gascoyne Inlet. To accomplish this task the meteorological conditions to be expected at the site need to be determined. As no data has yet been obtained at the site, historical data from the nearby Environment Canada station at Resolute Bay was used, along with a solar insolation model. This document shows the types of atmospheric conditions that are to be expected at the Arctic site based on the historical meteorological data sets and the insolation model. It shows that, if the Gascoyne Inlet installation is to operate year-round, equipment and personnel must withstand quite rigorous conditions. Equipment must be able to support winds gusting to 40 m/s and temperatures between -45 and 13°C. It also shows that the sky is clear 17 % of the time, cloudy 43 % of the time, foggy 18 % of the time, and that there is likely to be some kind of precipitation 30 % of the time. Finally, using historical solar irradiance data from Barrow, Alaska, and an insolation model, it shows that for equipment requiring 100 A-h at 12 V, a 1 square meter 100 % efficient solar panel could not provide more than 190 days of power and that alternate power would need to be available for at least 175 days or about half the year.
