Learn More about the Forecast

Wind

Wind forecasts display the forecasted sustained wind speed (in kilometres per hour) and wind direction, based on a 2-minute average, at approximately 1 metre above ground height. Wind forecasts are based on a blend of National Oceanic & Atmospheric Administration’s (“NOAA”) models and a unique algorithm from The Climate Corporation. The unique algorithm converts NOAA’s data, which forecast wind at 10 metres above the ground on a grid, into a forecast that displays the wind at boom height (50 cm above crop canopy). Wind speeds typically increase with height, so our boom height forecasts may be lower than wind forecasts from other sources. Wind can be impacted by many local factors, including topography, buildings and surrounding vegetation, so Wind forecasts are not a substitute for measuring wind with an anemometer or a similar device at the time of application. NOAA’s data classify each grid segment based on the dominant underlying surface characteristics and topography (e.g., farmland, forest, urban, water, etc.). As a result, Wind forecasts for fields in close proximity to varying land surfaces may have degraded accuracy due to the limitations of a discrete grid.

Inversion

Inversion Risk displays the forecasted probability, in percent, of a surface temperature inversion occurring at a specific location and time, which due to model variances is rounded to the nearest 5%. Inversion Risk forecasts are based on a blend of NOAA forecast models  and a unique algorithm from The Climate Corporation that combines multiple meteorological variables. Inversions can be impacted by many local factors, including topography, soil temperature, cloud cover or fog, wind, and water bodies, so Inversion Risk forecasts are not a substitute for assessing whether an inversion is present at the time of application. NOAA’s data classify each grid segment based on the dominant underlying surface characteristics and topography. As a result, Inversion Risk forecasts for fields in close proximity to varying land surfaces (e.g., nearby urban areas, water bodies and forests) may have degraded accuracy due to the limitations of a discrete grid.

Weather forecasts are updated throughout the day.

Temperature and Relative Humidity

Temperature and Relative Humidity forecasts are based on information from the National Weather Service’s (“NWS”) National Digital Forecast Database, which uses data from local NWS forecast offices and the National Centres for Environmental Prediction.

Legal

The RRXtend Spray app provides forecasts for locations within Canada. Forecasts are developed using publicly available weather data from the U.S. National Oceanic and Atmospheric Administration (NOAA) and unique models developed by The Climate Corporation. Do not use this app for forecasts outside of Canada. Forecasts are for planning purposes only and are not a substitute for checking actual weather conditions at your location at the time of application and complying with the product label and other legal requirements.
