AIR TEMPERATURE (RS03__)

Measurement period:: 19700413 - 19950710

Comments:

Daily Variables:
13 Apr 1970 to 27 Dec 1972:
Mean, max, min sunrise to sunrise temperature
Mean daytime, mean nighttime temperature
27 Dec 1972 to 20 Jan 1981:
Mean sunrise to sunrise temperature
Mean, max daytime temperature
Mean, min nighttime temperature
20 Jan 1981 to 10 Dec 1981:
Mean, max, min sunrise to sunrise temperature
Mean daytime, mean nighttime temperature
10 Dec 1981 to 10 July 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 (before 10 Sep 1980)
300 cm (beginning 10 Sep 1980, but sensor moved to 100cm
in summer until 1987, exact dates unknown)
235 cm (repositioned 01Oct 1991)

Notes: Before 27 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 10 Dec 1981.
Beginning 10 Dec 1981, 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.

SOIL TEMPERATURE (RS03__)

Measurement period:: 19700413 - 19950710

Comments:

Daily Variables:
13 Apr 1970 to 10 Dec 1981:
Mean sunrise to sunrise temperature only
10 Dec 1981 to 10 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 10 Dec 1981, 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.
