Daily Light Integral (DLI) measurement using LI-COR Light Sensors

January 8, 2013 LI-COR Biosciences

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…

Turn Ons and Turn Offs

October 5, 2009 LI-COR Biosciences

The LI-1400 Datalogger is often used for collecting environmental data using a variety of LI-COR Biosciences sensors. These include the LI-190 Quantum Sensor, the LI-192 Underwater Quantum Sensor, the LI-193 Spherical Quantum Sensor, and the LI-200 Pyranometer, among others. You can either program their LI-1400 to collect data automatically or set it up to collect data manually.

The LI-1400 has a power-saving mode to help conserve the batteries by…

It’s Pyranometer Calibration Season

July 5, 2009 LI-COR Biosciences

The LI-200 Pyranometer Calibration schedule will be reaching its annual suspension on October 1st, 2011 and continuing through until February 28th, 2012.

LI-COR encourages our customers to return their LI-200 Pyranometer Sensors for recalibration (suggested every 2 years after field deployment) between the months of March and September. Why? Because pyranometer sensors need to be calibrated outdoors in natural sunlight in order to construct an accurate relationship between the output of each sensor and incoming solar radiation. During LI-COR’s 40…
