Hourly in-situ meteorological observations from 1953 to 2005 for Canada and from 1871 to 2001 for the former USSR. The dataset is a joint compilation by the Meteorological Service of Canada, Russia's Research Institute for Hydrometeorological Information, and NOAA's National Climatic Data Center. It includes data from up to 170 active Canadian stations and over 2,000 stations across the former Soviet Union.
Use Cases
- Analyzing long-term trends in surface air temperature and sea level pressure across Canada and Russia.
- Studying historical relationships between water vapor pressure, relative humidity, and cloudiness characteristics.
- Modeling wind patterns using hourly wind speed and direction data from specific station locations.
- Investigating changes in present weather conditions over the 20th century in the former USSR.
Strengths
- Over 50 years of hourly data for Canada (1953-2005).
- Historical coverage for the former USSR spans 130 years (1871-2001).
- Includes up to 2,095 station locations across the former Soviet Union prior to 1991.
Limitations
- Data recency is limited, with the latest updates from 2001 and 2005.
- The number of stations in the former USSR subset varies significantly over time, complicating longitudinal analysis.
- Approximately 350 Canadian stations are updatable only with a delay, indicating potential data gaps.
