Improved Daily Light Integrals with Satellite Data

Improved Daily Light Integrals with Satellite Data

From its introduction forty years ago, the Daily Light Integral (DLI) metric has become an important tool for determining monthly daylight availability for crops and estimating supplemental electric lighting requirements for greenhouses. DLI charts for the continental United States have been available for nearly two decades, but it has only been in the past year or so that DLI information for geographic locations worldwide has been made available through various online DLI calculators.

Our Food Security:

Recent public health events have highlighted the need for food security in local communities. In northern (and less hospitable) climates like Canada long term, year round food growth will depend on indoor facilities such as greenhouses, vertical farms (plant factories), and hybrid facilities. Proper lighting is critical for these facilities to successfully produce the necessary quality and quantity of food to sustain the population at a reasonable cost. SunTracker has developed CAD modelling tools to allow the horticultural industry to assess and specify the most efficient and effective commercial lighting for the horticulture industry, lighting that is critical for the sustainability of food security.
