Data provided herein is for the Shingle Creek Ridge weather station  (SCR) of Dry Creek Experimental Watershed, Boise, Idaho.

DATA STREAM:  

1. Measurement site was installed by Boise State University (Student Dave Eirikkson) of Boise, Idaho, late 2010 with 
data collection initiated 9/26/2010.  Data collection and site maintenance is provided by Boise State University 
Hydrologic Sciences. Instrumentation installed includes air temperature, relative humidity, wind direction and speed,
4 component radiation, shielded precipitation by Hach OTT weighing bucket gage. One soil moisture sensor and thermocouple 
was installed at 5 cm depth adjacent to the weather station tower, south side. 

2. Data files collected via Campbell Scientific datalogger are telemetered and compiled. This is level 0, raw data 
(CUAHSI HIS standards).  
(CUAHSI HIS standards, 0 = raw data,  1 = Quality controlled data that have passed quality assurance procedures such as 
routine estimation of timing and sensor calibration or visual inspection and removal of obvious errors, 2 = Derived products 
that require scientific and technical interpretation and may include multiple-sensor data. An example is basin average 
precipitation derived from rain gages using an interpolation procedure.) 

3.  Data as collected and provided is, by protocol in mountain standard time, year-round. 


SITE NOTES:

The Shingle Creek Ridge weather station is located on a low ridge spur within the Shingle Creek headwater catchment. 
This headwater catchment is overall west-facing, originating on the eastern edge of Dry Creek Watershed as a perennial spring 
fed tributary to Dry Creek. At 1720 m elevation, SCR is located within the rain-snow transition zone for winter precipitation 
on the Boise Front. Soil at the site is primarily sandy loam, with depth varying from 0-100 cm above fractured crystalline 
bedrock. Vegetation includes grass, low brush, tall shrub and sparse Ponderosa pine and Douglas fir.


DATA/INSTRUMENT NOTES:

SOIL MOISTURE, TEMPERATURE - data assessed as invalid to date. 'CR10XTCR Thermistor Temperature (Located on multiplexor to be used 
as ref temp for thermocopules) '1 Copper Constantine Thermocouples (MUX), '1 CS616 Soil moisture sensors(MUX), moved from mux to CR1000. 
'Note:  As of 10/18/2010 one out of four soil moisture sensors installed -- located ~5 m south of main 'tripod at 5cm depth.  
**Currently calibrated using default settings. Published values are INSTANTANEOUS on the hour measurement.
HOURLY AVERAGE MEASUREMENTS are available upon request.
Hourly average measurement is a function of scan rate, as frequent as 1 minute, 10 minute used when necessary to reduce power consumption.
