CANOPY: None overhead, though insolation affected slightly from trees on adjacent hillsides.
CONTINUOUS, OPEN CANOPY TYPE.

SURFACE: Short grass/dirt, generally clear of vegetation.

SENSOR: Cotton shelter, enclosed sensor (1.5 m).  Also a thermister tower (1.5, 2.5, 3.5, 4.5 m),
but long-term sensor is enclosed one.

GENERAL SITE CHARACTERISTICS:
Level, open MET site at HJA headquarters, one of the long-term benchmark sites in the HJ Andrews. 
Long-term temperature measurements are from an enclosed sensor in a cotton shelter.  Site is close
to Lookout Creek, at the bottom of the valley; cold-air drainage possibly influences this site.
Little difference between topographic and canopy insolation blocking, except during winter months. 
Trees to north much closer than trees to the south.  Along with CS2MET, appears have cooler and
somewhat unusual long-term temperature trends compared to the rest of the HJ Andrews.

CANOPY: Closest site to having 45 degree cone overhead.  Canopy slightly more open to the east than
other directions.  CONTINUOUS, OPEN CANOPY TYPE.

SURFACE: Tends to be bushy with thick short shrubbery and grass.

SENSOR: 1.3 m thermister, shielded above with PVC.

GENERAL SITE CHARACTERISTICS:
The longest running site in the HJ Andrews.  Surrounded on all sides by thick forest with tall trees,
located directly in middle of clearing (15-20m from trees).  Located in a clearing up and across the
main road from Lookout Creek, with cold-air drainage possibly affecting temperature regime.  Surrounding forest plays a major role in insolation regime, though site is completely open directly
above.  Along with PRIMET, , appears have cooler and somewhat unusual long-term temperature trends
compared to the rest of the HJ Andrews.

CANOPY: The most open site in the HJ Andrews.  Horizon visible east-south-west.  Trees not a
factor for insolation.

SURFACE: Mixed short grass, brush, dirt

SENSOR: 1.5 m thermister, shielded above with PVC, on thermister tower (1.5, 2.5, 3.5, 4.5 m
sensors).  Recording sensor height varied during operating period between .5 and 2.5 m.


GENERAL SITE CHARACTERISTICS:
One of the benchmark MET sites.  On a south-facing slope with horizon fully visible in that
direction.  Sparse forest begins 20-30 m to the north.  In a large clear-cut with an expansive

SURFACE: Mixed short grass, brush, dirt.

SENSOR: 1.5 m thermister, shielded above with PVC, on thermister tower (1.5, 2.5, 3.5, 4.5 m
sensors).

GENERAL SITE CHARACTERISTICS:
The highest of the benchmark MET sites.  On gentle east-facing slope, with horizon visible in all
directions, though slight topographic shading to the southwest in winter.  Very open, in a large
clear-cut.  Presence of young trees growing in clearcut provides some insolation blockeage; nearest
forest starts due east 70-80 m.  Due to openness and reliability of insolation and temperature
data, this site was used to determine percentages of diffuse and direct radiation for each month
in the study.

CANOPY: None directly overhead, but site surrounded by moderate forest.
CONTINUOUS, OPEN CANOPY TYPE.

SURFACE: Gravel and dirt.

SENSOR: 1.5 m thermister, shielded above with PVC.  Recording sensor height varied during period
of operation between 1.5 m (6 years) and 4.8 m (1.5 years).

GENERAL SITE CHARACTERISTICS:
At the confluence of 2 roads in moderate forest.  Site is thus unusual by having large open areas
radiating out from it through the surrounding forest.  Attenuation is completely by surrounding
trees, about 20 m from sensor in each direction.  More open to direct radiation from the southwest
for most months (direct sun in the mornings).  During June and July site receives direct radiation
through much of the day but during other months sun is blocked by forest wall to the south.
