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.
