AIR TEMPERATURE (RS15__)

Measurement period:: 19720701 - 19941013

Comments:

Daily Variables:
01 Jul 1972 to 03 Dec 1972:
Mean, max, min sunrise to sunrise temperature
Mean daytime, mean nighttime temperature
03 Dec 1972 to 21 Jan 1981:
Mean sunrise to sunrise temperature
Mean, max daytime temperature
Mean, min nighttime temperature
21 Jan 1981 to 11 Jan 1982:
Mean, max, min sunrise to sunrise temperature
Mean daytime, mean nighttime temperature
11 Jan 1982 to 13 Oct 1994:
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
180 cm (repositioned 01 Oct 1991)

Notes: Before 03 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 11 Jan 1982.
Beginning 11 Jan 1982, 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 (RS15__)

Measurement period:: 19720701 - 19941013

Comments:

Daily Variables:
01 Jul 1972 to 11 Jan 1982:
Mean sunrise to sunrise temperature only
11 Jan 1982 to 13 Oct 1994:
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 11 Jan 1982, 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.
