Site
Location
Site is located in the NEED camp of the Whiskeytown-Shasta-Trinity Recreational Area, under the auspices of the US National Park Service. WDC is also a cooperative station with the Advanced National Seismic System.
Network
BK, BARD (Berkeley Digital Seismic Network and Bay Area Regional Deformation Network)
Geology
Gneiss
Vault/Borehole Conditions
The sensors are located approximately 150' into a tunnel and encased in a steel tank which is located on a poured concrete pad. Approximately 25 meters of overburden cover the tunnel. The datalogger and supporting equipment is located in an external building and connected via conduits.GPS Monument Description
Steel four-pod, driven 10ft to refusal -

GPS Data Quality
Completeness
Data completeness is defined both as "Completeness of observations" and "Cycle slips per observation". "Completeness of Obs." is the number of epochs in the final RINEX file normalized to the expected number. This percentage will go down if time is missing from the RINEX file. "Cycle slips per Obs." is the total number of detected cycle slip normalized to the total number of observations in the RINEX file. This number will increase as the receiver loses lock on satellites more frequently.

Multipath
The effects of multipath on the data are estimated by parameters for L1 and L2 (MP1 and MP2 respectively); see Estey and Meertens (GPS Solutions, 1999) for derivation. The daily value is the RMS of MP1 and MP2 throughout the day and for all satellites. Higher values indicate a greater prevalence and/or strength of multipathing, i.e. objects on the ground are providing multiple reflection pathways from the satellite to antenna.
