Temperature and Dew Point
There is only a single weather station, Clyde River Climate, in our network suitable to be used as a proxy for the historical temperature and dew point records of Clyde River.
At a distance of 3 kilometers from Clyde River, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and Clyde River according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
