This manual outlines the products and features of the "WeatherFarm Peace River District" website. The network represents Adcon, Davis and WeatherFarm stations in the Peace River region. Limited access to information is available to the general public on the home page; however, simply sign up and log in to gain access to a collection of management tools, historical and current weather data, maps and information.

Plot your Field
Add a virtual field of wheat, other, or beehive
My Fields Historical Weather (Metric or Imperial)
Compare My Fields Weather (Metric or Imperial) in both table and graph form
Compare all your registered fields at once with the following parameters:Daily Maximum Temperature (°C), Daily Minimum Temperature (°C), Daily Average Temperature (°C), Daily Rain (mm), Daily Average RH (%), Hourly Average Temperature (°C), and Hourly RH (%)
My Fields Forecast in both table and graph form
Compare My Fields Forecast
Compare all available forecasts in graph form, with the bolded line as the average
Maximum Temperature (°C), Minimum Temperature (°C), Rain (mm), RH (%)
Growing Degree Days
Calculate the GDD for your locations by choosing a start and end date, a base temperature, and metric or imperial
Displays the daily GDD value and the accumulated GDD value in both table and graph form
Forecasts bee flight activity based on behavioural and weather conditions for the next 3 days
Hourly flight activity is colour coded representing no activity, very low activity, low activity, medium activity, and high activity
Gives operators a quick visual of when the best time is to spray to minimize the impact on bee activity
Can adjust boom height from 0.6 metres (2 feet) to 1.2 metres (4 feet)
Check whether your field is getting enough rain by entering a start and end date
ET values can be used to determine whether irrigation is required, by estimating how much moisture is being lost
Soil Water Balance
Check whether your field is too wet or too dry by entering a planting date
SWB is displayed in colour blocks in 5 day increments, based on the percentage of available water (AW) in the soil between field capacity and wilting point
SWB is described as highly favourable (81-100% AW), favourable (61-80% AW), reasonable (51-60% AW), non-favourable (31-50% AW), or critical (0-30% AW)
Crop Heat Unit
Daily and accumulated CHU values are calculated for your location starting on May 1st
Displayed in both graph and table form
Forecasts the optimal time to turn on your bin fan based on the predicted Equilibrium Moisture Content (EMC) in the next 5 days, in 1 hour increments
Adjusts based on the type of grain in the bin
The darker the colour scale or the loser the EMC %, the better drying quality of the air
Receive an email or text on your field locations if it reaches certain customizable thresholds
Parameters include: Temperature (°C) both a minimum and maximum, Rain (mm), and Wind Speed (km/h)
Easily set the same alerts for all registered fields
Fusarium Head Blight Tool (Wheat)
Predicts your wheat fields risk of fusarium head blight based on the heading date
Daily risk is displayed as either Low, Moderate, or High, 5 days before your expected heading date and 4 days after, giving a 10 day colour coded FHB risk tool
Growth Stages (various crops)
Growth stage models are available for spring wheat, winter wheat, spring barley, canola, oats, flax, sunflower, chickpea, lentil, and pea
All GDD based and start accumulating on planting date
Estimates various stages of a particular crop based on raw weather data, forecast data, and normal data
Dew Point Information
The temperature at which air is sufficiently cooled to reach saturation and condense water vapour from the air is known as the dew point (Moran and Morgan, 1997). If this temperature is below freezing, frost (rather than dew) will form. This is often referred to as the frost point. If there is a large difference between the air temperature and the dew point, the air is drier, and vice versa. Consequently, dew point is a measure of atmospheric moisture.
Forecast data is generated using a combination of several forecasting model that has proved to more accurately reflect some weather patterns. Daily forecast includes the parameters Tmax, Tmin, rain and RH for the next 12 days.
Hourly forecast includes temperature, rain, RH, wind speed and wind direction values for the next 12 days.
Both daily and hourly forecasts can be view as a graph or table.
Growing Degree Days Information
Growing degree days are a measure of how many heat units are accumulated in a single day or over time. They are calculated on a daily basis using the daily maximum and minimum temperature. WIN calculates GDD using the following formula:
(Daily Tmax + Daily Tmin) /2 - Base
The GDD are presented in a table of growing degree days. This table is shown in the figure below. A user can subsequently choose a start and end date and the total accumulated GDD for that period is displayed immediately above the table. This information will give growers a sense of the week, the month, the year, or any time period that is chosen, in terms of it accumulating more or less heat units
The GDD calculation runs from March 1 to October 31.
The historical data is available in hourly and daily formats. Users can select the format, as well as the time period they are interested in. Please note that login is required to access these features. User can also view the graph and data is available to download in spreadsheet. All data is archived at the beginning of April every year, in order to enable access to the entire winter season. Consequently, between the months of January to March, WIN enables 13-15 months of accessible daily data. Nevertheless, archived data can be made available upon request. Please note that a fee may be required, depending on the application.
Individual Grower Defined Alerts for Temperature, Wind, and Rain
Growers can set specific alerts for forecast data at their network station. The thresholds can be changed and alerts can be turned off any time from the user's dashboard. Alerts are sent out daily using 4km grid of hourly weather forecast which is loaded in WIN's database everyday.
