In photobiologySun: Data for Sunlight Spectra
ppfd_LICOR.data R Documentation
Ground level solar PAR photon irradiance (measured)
Description
Dataset containing mean, maximum, minimum and standard deviation values for
photosynthetically active radiaition expresed as photon irradiance. Each value is a summary
60 consecutive readings acquired once every second.
Usage
ppfd_LICOR.data
Format
A data frame with 24479 rows and 5 variables.
Details
The variables are as follows:
time_EEST POSIXct Local time according to EET coordinates.
ppfd_mean numeric (umol m-2 m-2)
ppfd_min numeric (umol m-2 m-2)
ppfd_max numeric (umol m-2 m-2)
ppfd_sd numeric (umol m-2 m-2)
Note
Instrument used: LI-COR LI-190 quantum sensor, mounted
on tripod at approximately 2 m height. Data collected with a Campbell
Scientific CR6 datalogger. Sensor connected through a LI-COR millivolt adaptor
(604 ohm). Wavelength sensitivity range of the quantum sensor
is 400 nm to 700 nm. Location: Viikki campus of the University of Helsinki.
Coordinates: 60.226803 N, 25.019205 E.
