PRIMET (Water Vapor Pressure Deficit)
Site description: Maintained clearing
Latitude: 44-12-43 Longitude: 122-15-21 Elevation (MSL): 430 meters
Aspect: - degrees Slope: 0 degrees
Measurement period: 19880706 - Present

Daily Variables:
06 Jul 1988 to 13 Sep 1994:
Mean, max, min daily (midnight to midnight) vapor pressure deficit
Mean, max, min daytime vapor pressure deficit
Mean, max, min nighttime vapor pressure deficit
Time of max, time of min for daily, daytime, nighttime
13 Sep 1994 to Present:
Mean, max, min daily (midnight to midnight) vapor pressure deficit
Daily time of max, time of min
Fine Resolution Variables:
06 Jul 1988 to Present:
Mean hourly vapor pressure deficit
Sensor height: 06 Jul 1988 to 30 May 2000 : 150 cm cotton shelter (probe 05)
04 Jun 1998 to present: 150 cm on tower (probe 04)
30 May 2000 to present: 450 cm on tower (probe 01)
Notes: After 06 Jul 1988, water vapor pressure deficit is calculated from air temperature
and relative humidity sensors located in the 150 cm cotton shelter every 15 seconds (in
millibars). Since 04 Jun 1998, an additional probe at 150 cm on the tower was used to calculate
water vapor pressure deficit. On 30 May 2000, use of the 150 cm cotton shelter probe to calculate
water vapor pressure deficit was discontinued and replaced with the use of the 450 cm probe on the
tower .
Daytime and nighttime calculations are discontinued 13 Sep 1994.
