Taking readings

Using the Emulator mode

You have now configured all the settings necessary to start taking readings, including setting SunData into emulator mode, with BFS, and setting the display to LAI At its simplest, you only need to press Enter twice to take, display and store each Leaf Area Index reading, and the values it is derived from:

♦Press Enter once to collect and display an (emulated) reading.

♦Press Enter again to

store that reading, and return to the Next

Reading screen.

....or possibly

Use the ← → arrow keys to select DISCARD before pressing Enter, in which case the reading will not be stored, ...and optionally

♦Use the ← → arrow keys to select NOTE

before pressing Enter, so that you can add a note to the reading before it is stored.

Reading labels uniquely identify each reading. They can be edited in the Next Reading screen by using the ↑ key.

PAR in ∝ mol.m-2.s-1above the canopy, measured by Beam Fraction sensor.

PAR within the canopy, measured by the SunScan probe (or emulated).

Fraction of PAR in the direct solar beam compared to total incident PAR (Direct + Diffuse) above the canopy.

Leaf Area Index, calculated from the readings shown and the parameters entered earlier.

Current time, and calculated solar angle.

Spread of readings from individual photodiodes along the probe wand.
