AIR TEMPERATURE (RS01__)

Measurement period:: 19700417 - 19950715

Comments:

Daily Variables:
17 Apr 1970 to 31 Dec 1972:
Mean, max, min sunrise to sunrise temperature
Mean daytime, mean nighttime temperature
31 Dec 1972 to 22 Jan 1981:
Mean sunrise to sunrise temperature
Mean, max daytime temperature
Mean, min nighttime temperature
22 Jan 1981 to 07 Jan 1987:
Mean, max, min sunrise to sunrise temperature
Mean daytime, mean nighttime temperature
07 Jan 1987 to 15 Jul 1995:
Mean, max, min daily (midnight to midnight) temperature
Mean, max, min daytime temperature
Mean, max, min nighttime temperature
Time of max, time of min for daily, daytime, nighttime

Sensor height: 100 cm
80 cm (repositioned 911001)

Notes: Before 31 Dec 1972, daytime length was determined for the 15th of the
month, and used for the entire month. After this time, an algorithm
was developed to determine daily day length. Changes in measured
temperature parameters were due to changes in the digitizing program
used to process chart data. All daily summaries are based on a
sunrise to sunrise day before 07 Jan 1987.
Beginning 07 Jan 1987, a true daily summary is available due to the use
of a revised digitizing program. The revised program produces output
similar to the CR10 dataloggers used for thermographs.
Measurement at this site discontinued 15 Jul 1995.

SOIL TEMPERATURE (RS01__)

Measurement period:: 19700417 - 19950715

Comments:

Daily Variables:
17 Apr 1970 to 07 Jan 1987:
Mean sunrise to sunrise temperature only
07 Jan 1987 to 15 Jul 1995:
Mean, max, min daily (midnight to midnight) temperature
Mean, max, min daytime temperature
Mean, max, min nighttime temperature
Time of max, time of min for daily, daytime, nighttime

Sensor depth: 20 cm

Notes: Soil temperature was digitized on a sunrise to sunrise basis.
After 07 Jan 1987, a true daily summary is available due to the use
of a revised digitizing program. The revised program produces
output similar to the CR10 dataloggers used for thermographs.
