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

DATA STREAM:  

1. Measurement site was installed by Boise State University (Student Dave Eirikssen) of Boise, Idaho, October 2012 with 
partial data collection initiated 11/24/2012.  Data collection and site maintenance is provided by Boise State University 
Hydrologic Sciences. 

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. Selected timeseries are quality checked and post processed for gapfilling, noise filtering and/or corrected according 
to established instrument calibrations. Data is NOT GAPFILLED after 4/1/2014. See ERRORS/GAPS/UPDATES below.

4.  Data as collected and provided is, by protocol in mountain standard time, year-round. Data was collected at 15min 
interval to June 10, 2013. A data gap occurs until 4/1/2014 when data collection resumed as hourly.



SITE NOTES:
   
BRW is located on the northern ridge line of east-facing Clear Creek watershed, immediately adjacent to DCEW headwater basin.  
At 2114 m elevation, BRW is located above the rain-snow transition zone for winter precipitation on the Boise Front.   
Based on historical records from adjacent sites, average annual precipitation at BRW is expected to be between 700 and 800 mm, 
with snowpack generally two meter s deep or less, December through May.   Soil at the site is sandy loam, zero to one meter depth 
above fractured crystalline bedrock.  Vegetation includes minor low profile grass and forbs, broad thickets of ceanothus,sparse 
Ponderosa pine and Douglas fir. The Hillslope location at which the two soil pits are located is forested, south facing.


DATA/INSTRUMENT NOTES:

Soil measurements - HILLSLOPE LOCATION EAST OF WEATHER STATION TOWER: 

Location is approximately 40m east of the weather station tower. 
Sensors are Stevens Hydraprobes. Two pits are emplaced at BRW hillslope measurement site, upper and lower.   
4 Stevens sensors are located in each pit. Depths of sensor emplacement  is 5, 15, 30 and bedrock
81 cm lower, 55 cm upper. Total pit depth 70 cm at upper pit.  Sensor SDI and serial numbers, in order from lower 
pit 5 cm to bedrk and upper pit 5 cm to bedrock.

Data available from the Stevens Hydraprobes include a Basic data table and an All data table.  The data provided in the files
herein are from the Basic data table.  We periodically collect the All data table which includes soil conductivity and 
additional geophysical soil parameters related to soil moisture. The Lysimeter and All data tables are available on request. 


Snowmelt Lysimeters are installed adjacent to the soil pits. Tipping buckets measure snowmelt over time. Four 
tipping buckets are installed, with two parallel buckets per snowmelt plot. 



ERRORS/GAPS/UPDATES:


2012-2013
Hillslope - The hillslope soil pit(s) and lysimeter plot have been installed under the supervision of HP Marshall 2012-2014
with work accomplished by students, Dave Eirikssen, Hank Hetrick and Andrew Karlson.  These students have
also provided data retrieval, processing and site maintenance. 15 minute data 11/24/2012 to 6/10/2013, 
at which point data collection ends for 2013. Minor gap 3/11/2013.


2014
Hillslope -Data collection resumes 4/1/2014.  Due to logger failure to communicate, a replacement logger SN 60719 CR1000, purchased by Jim 
McNamara Fall 2013, is being installed by Andrew. 04/11/14  confirm two working tipping buckets that 
are also producing data, TB2 and TB4...confirmed that 2, 3, and 4 buckets are actually functional, while bucket 1 is not.  
pulse port 1 = tip bucket 2  and pulse port 2 = tip bucket 4.  This means that in the data output after today,the column 
that states TB1 is actually TB2, similarly for TB2  = TB4.  control port(com) 3 = tip bucket 1 and 
control port(com) 4 = tip bucket 3;   

2015
Hillslope - May data download.  site is functional. Data collection ends 5/29/2015. 

2016
Hillslope - Data collection resumes 3/1/2016.  Data gap 3/18 to 4/24/2016. Data continues through 2016. 

2017
No data gaps. Late spring sporadic no data values occur, NAN, replaced by -6999. 



NOTE:  CURRENT YEAR DATA IS PROVISIONAL.  

All data sets may be error corrected at year-end.
Precipitation data and snow data undergo smoothing 
and additional data filter processing at year end 
in contrast to raw data that may be published "realtime".
