Daylight Solarimeter to PPFD Calculator

Calculate PPFD



Formula

The formula to calculate PPFD (\(µmol m^{-2} s^{-1}\)) from Solar Radiation (W/m²) is:

\[ PPFD = Solar\ Radiation \times Conversion\ Factor \]

Where:

Definition

PPFD (Photosynthetic Photon Flux Density) is a measure of the number of photons in the photosynthetically active radiation (PAR) range that are incident on a surface every second.

Solar Radiation is the radiant energy emitted by the sun, particularly electromagnetic energy.

How to calculate PPFD from Solar Radiation

Let's assume the following value:

Using the formula:

\[ PPFD = 200 \times 2.15 \]

Evaluating:

\[ PPFD = 430 \]

The PPFD is 430 µmol m⁻² s⁻¹.
