About
Daily country average precipitation and air temperature data in metric units for Finland, Norway, and Sweden, spanning 2015 through 2019. The data was processed from observations collected across 1,306 distinct weather stations by the National Centers For Environmental Information (NCEI). This resource provides clean, aggregated daily measurements suitable for macro-level climate analysis and time series studies focused on the Nordic region.
Columns
- country: Identifies the nation of observation (Finland, Norway, or Sweden).
- date: The specific date of the observation, ranging from 1 January 2015 to 31 December 2019.
- precipitation: The amount of fallen rain, snow, or hail, measured in centimetres (cm).
- snow_depth: The height of collected snow on the ground, measured in millimetres (mm).
- tavg: The country-wide average of the daily mean temperatures, measured in degrees Celsius (°C).
- tmax: The country-wide average of the daily maximum temperatures, measured in degrees Celsius (°C).
- tmin: The country-wide average of the daily minimum temperatures, measured in degrees Celsius (°C).
Distribution
The product is provided as a data file, usually in CSV format, with a size of approximately 396.89 kB. It contains 7 columns and 5,478 total valid records. The data aggregates detailed raw observations (which totalled over 4.8 million) from weather stations across the three nations into consistent daily country averages. The original data had notable amounts of missing values, particularly for snow depth and temperature averages, which have been addressed through imputation using the daily mean.
Usage
Ideal applications for this resource include:
- Performing Time Series Analysis to model seasonal changes and long-term climate trends.
- Conducting Exploratory Data Analysis (EDA) of Nordic weather patterns.
- Developing and training environmental or meteorological models.
- Geographical comparison of climatic variables across the three countries.
Coverage
The scope is geographical, covering the three Nordic nations: Finland, Norway, and Sweden. The temporal coverage spans five full years, from 1 January 2015 to 31 December 2019. The data represents aggregated country averages, rather than individual station readings. Data availability notes indicate that the initial raw data exhibited high levels of missingness (up to 99% for some variables in certain countries), which necessitated the use of daily means for imputation prior to aggregation.
