    Argo Canada

    Argo is a global in situ ocean climate monitoring system consisting in an array of over 4,000 free-drifting floats that collect data on ocean temperature and salinity, and sometimes oxygen, in the upper 2000 m of the ocean. It is an international effort, with more than 30 nations contributing...

    Canadian National Tornado Database: Verified Events (1980-2009) - Public

    A database of verified tornado occurrences across Canada has been created covering the 30-year period from 1980 to 2009. The data are stored in a Microsoft Excel spreadsheet, including fields for date, time, location, Fujita Rating (intensity), path information, fatalities, injuries, and damage...

    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,...

    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...

    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....

    Dry Spell

    Dry spell periods are defined as a count of the number of days within the date range where daily precipitation was less than 0.5 mm. Consecutive days below 0.5 mm is a count of the number of days, starting from the date of the product and going back in time, since there has been a day with...

    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...

    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...
