Climate station data from Purple Valley at the head of Milne Fiord, northern Ellesmere Island, Nunavut, Canada.

This dataset provides a long-term weather record from Purple Valley, Ellesmere Island. This location is near the head of Milne Fiord and can serve as an index location for the region adjacent to the ice shelves of northern Ellesmere Island. Weather data were observed every 4 minutes by an automated weather station, averaged and recorded hourly and transmitted daily using a satellite data connection. The station was a 3 m tripod with a Hobo Energy Pro logger, an Iridium satellite transceiver, a solar panel/battery bank, and the following data are available: air temperature at 1 m above surface, air temperature at 2 m above surface, relative humidity at 2 m above surface, wind direction and wind speed at 4 m above surface, incoming radiation at 3 m above surface, atmospheric pressure, and snow depth. The station is located at the east end of Purple Valley (82.483986°N, 80.7881122°W at 20 m asl) above the valley floor and a few hundred metres south of a little bay in Milne Fiord. It is on a small area of level ground at the top of a bench along the slope of an arrete that borders Milne Fiord. The immediate surroundings are bare, flat ground with sparse polar desert vegetation. Note that the snow conditions at this site are not representative of the general area as the bench where the station was located is exposed and often blows clear.
