Daily Light Integral (DLI) maps display the ambient light delivered daily during each month across the entire U.S. These maps were researched and developed by James Faust of Clemson University and Joanne Logan of The University of Tennessee. They are unique because DLI is a measurement of light that is particularly valuable for estimating plant growth. Other solar radiation maps created for photovoltaic purposes, i.e., installing solar panels, are not directly applicable to horticultural applications.<\/p>\n\n\n\n

According to Faust, the project leader, the DLI maps are valuable because they allow growers to better manage the light environment of their plants. \u201cFor example, one can estimate the number of days per year that supplemental lighting may be necessary to achieve the desired plant growth during winter months or how much shade cloth may be required to reduce the light intensity delivered to crops during the summer months,\u201d says Faust.<\/p>\n\n\n\n

The new maps provide high-resolution data. For example, an individual data point for every 10 km2<\/sup> across the U.S., from 21st-century data. GPN Magazine published the previous version of the maps in 2002. The editor said that this issue was the most requested one that they have ever had.<\/p>\n\n\n\n
