- Series
- 1951-1971
Series consists of environmental monitoring raw data in the form of anemograph charts (1955-1970), gauge cards (1955-1967), rainfall charts (1955-1959, 1971) and snow surveys (1963-1964). An anemograph chart is a paper record of the direction and force of the wind; gauge cards contain data recorded manually by gauge readers at gauge stations along the Grand River; rainfall charts contain daily entries recording rainfall; snow surveys consist of booklets containing pre-printed pages for entering snow data. Although this data is not complete it is nonetheless important for providing a means whereby climatic and environmental change over time can be analyzed.
