    Versatile Soil Moisture Budget

    The Versatile Soil Moisture Budget (VSMB) is a soil water budget model that is continuous and deterministic in nature and was developed by AAFC. It is based on the premise that the water available for plant growth is gained by precipitation or irrigation, and lost through evapotranspiration and...

    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....

    Percent of Average Precipitation

    Percent of Average Precipitation products compute the accumulated precipitation value for a location and divide it by the long term average value at that location. The long term average value is currently defined as the average amount over the period of 1981 – 2010. Products are produced for...

    Heat Wave

    Days above 25 and 30 degrees Celsius are defined as a count of the number of days within the date range where the maximum daily temperature was greater than 25 or 30 degrees respectively. Consecutive days above 25, 30 and 32 degrees Celsius is a count of the number of days, starting from the...

    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...

    Departure from Average Precipitation

    Departure from Average Precipitation products compute the accumulated precipitation value for a location and subtract the long term average value at that location from it. The long term average value is currently defined as the average amount over the period of 1981 – 2010. If the resultant value...

    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...

    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...
