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

DATA STREAM:  

1. Measurement site was installed by Boise State University (Student Reggie Walters) of Boise, Idaho, October 2011 with 
partial data collection initiated 11/15/2011, complete collection on 1/27/2012.  Data collection and site maintenance is 
provided by Boise State University Hydrologic Sciences. Soil moisture sensors, 
thermocouples and heat flux plates are installed adjacent to the weather station tower. 

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 hourly timeseries are quality checked and post processed for gapfilling, noise filtering and/or corrected according 
to established instrument calibrations. 

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


SITE NOTES:

As the fifth weather station established in support of ongoing hydrologic research in Dry Creek Experimental Watershed (DCEW), 
this site is officially named “Bogus Ridge Weather” station (BRW). Instrumentation with corresponding data series provides 
measurement of soil temperature, soil moisture, soil heat flux and four component shortwave/longwave radiation, IR,
along with additional meteorological variables.   
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.


DATA/INSTRUMENT NOTES:

RIDGE LOCATION AT WEATHER STATION TOWER, Soil measurement variables:

Campbell Scientific CS-650 Soil Moisture SDI-12 Sensor measurements VWC, EC, T ; Huxeflux HFP-01 Soil Heat Flux

Soil is sandy loam with weathered granite bedrock at approximately 35 cm. 
Soil Moisture (T and EC) Sensors are installed at 5 cm and 20 cm in each of the two pits.  
Two soil pits were installed proximate to the weather tower, at approximately 4.5 meters Northwest and Southeast of the tower. 
SE pit 1 includes sensors #1 and #2. Sensors #3 and #4 are in the NW pit 2. 
Sensor #1 and sensor #3 are the shallow sensors, 5 cm; #2 and #4 are at 20 cm.  
SDI adress #4, #5 are sensors 1 and 2, while address #6, #7 are sensors 3 and 4.
 

Soil moisture, temperature and ec are hourly instantaneous values.  
Precision soil moi 0.001, T 0.1 C, EC .001 dS/m (0.001 mS/cm)


ERRORS/GAPS/UPDATES:

2011
Ridge - partial data collection initiated 11/15/2011.

2012
Ridge - no data for below ground prior to Jan 27, 2012  1515. Gap 8/31-9/3. sporadic gaps from 10/4/12. 

2013
Ridge -  program changed on 1/22/13. Minor gap 2/26-2/27.

2014
Ridge - Data gap April 16 to May 29 via data loss, 2014. 
soil data failure 8/2- 9/19. 
 
2015

2016
minor gap 4/21. 10/12 1400. 10/22. 

2017
Data gap March 10-14. Gap 8/18 1200-1700, site visit. 8/18-8/24 temporary logger program (data column) change.

2018
Anomalies in battery power values occur summer 2018. Gap 10/19 - 10/22 due to work on site, program change, logger failed to maintain 
program loaded. Gaps 12/21-12/26 due to possible power-regulator error, possible logger corruption, potentially due to sensor open
circuit.
Fall 2018 datalogger program is updated to output hrly avg soil moisture, as well as hrly sample measurements.  
Heat flux remains as hrly avg. 

2019
Gap 1/10/ - 1/21. Data gap from 1/31 5:00 to 3/1/2019 1800.

2020
Gap 3/29-4/20 low bat. 

2021
Gap 2/18-2/25 low bat. 

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".
