    Total domestic expenditures on research and development (R&D) as percentage of gross domestic product (GDP). This table is included in Section D: Postsecondary education: Research and development of the Pan Canadian Education Indicators Program (PCEIP). PCEIP draws from a wide variety of data...

    Current Precipitation Compared to Historical Distribution

    Precipitation percentile products are created by comparing the accumulated precipitation amounts (mm) for the time period being processed against all available historical information from the same window of time. This comparison will rank the current amount and assign it a percentile value...

    Temperature Difference From Normal

    These values are computed by subtracting the normal monthly average temperature from the average monthly temperature of the month. The average monthly temperature is computed by obtaining the mean value of average daily temperatures for a month. If the month was colder than normal the value...

    Blended Index

    The Blended Index (BI) is a model which employs multiple potential indicators of drought and excess moisture (such as Palmer values, rolling precipitation amounts and soil moisture to name a few) and combines them into a weighted, normalized value between 0 and 100.The inputs and weights used in...

    Standardized Precipitation Index

    The Standardized Precipitation Index (SPI) is a widely used index to characterize meteorological drought on a range of timescales. The SPI can be compared across regions with markedly different climates. It quantifies observed precipitation as a standardized departure from a selected probability...

    Standardized Precipitation Evapotranspiration Index

    The Standardized Precipitation Evapotranspiration Index (SPEI) takes into account both precipitation and potential evapotranspiration (PET) and the resultant index is mostly used to highlight water deficits and droughts but can also show excesses. Thus, unlike the SPI, the SPEI captures the main...

    Palmer Drought Index

    The Palmer Drought Index (PDI) is a measurement of dryness based on recent precipitation and temperature and is based on a supply-and-demand model of soil moisture. The index has proven most effective in determining long-term drought, a matter of several months, but it is not as good with...

    Accumulated Precipitation

    Accumulated Precipitation represents the amount of total precipitation (solid and/or liquid in mm) which has been recorded over a given period of time. Products are produced for the following period types: Agricultural Year, Growing Season and Winter Season as well as rolling products for 7,...

    Minimum Temperature

    Minimum Temperature values hold the lowest recorded temperature value at each location in degrees Celsius for the given period type and date. Available period types are the previous 24 hours and the previous 7 days from the available date.

    Crop (corn) heat units

    Crop heat units (CHU) are based on a similar principle to growing degree days. CHUs are calculated on a daily basis, using the maximum and minimum temperatures; however, the equation that is used is quite different. The CHU model uses separate calculations for maximum and minimum temperatures....
