Daily Light Integral (DLI) measurement using LI-COR Light Sensors
Definition of DLI
The daily light integral (DLI) is a measure of the amount of light received in a single day in a particular area. For example, the number of moles of Photosynthetically Active Radiation (PAR) photons received during a single day in a square meter, or: mol m-2 d-1. Another example is the total solar radiation received during a single day in a square meter, or: W m-2. Depending on the application or research question the time integral of…
