CENMET (Solar Radiation (PAR))
Site description: Clearcut Nov 1986, natural regeneration
Latitude: 44-14-36 Longitude: 122- 8-30 Elevation (MSL): 1018 meters
Aspect: 260 degrees Slope: 12 degrees
Measurement period: 19980123 - Present
Comments:
Daily Variables:
23 Jan 1998 to Present:
Mean and max daily photosynthetically active radiation (PAR)
Time of max
High Resolution Variables:
23 Jan 1998 to Present:
Mean PAR in 15 minute intervals
Sensor height: 627 cm
Notes: Max solar radiation is based on instantaneous micromoles per second per square meter, and
the time of max is accurate to the minute.
It is common for solar radiation sensors to read negative at night (-1 to -7). Negative nighttime
readings are changed to 0. The daily values average in these negative values, creating a minor
error in the daily values.
