ORV - Oroville Dam, Oroville, CA, USA
|Station Name||ORV (ORVB)|
|In Operation||1992/07/31 18:50:00 - Present|
LocationSite is located near the Oroville Dam, and is under the auspices of the CA Department of Water Resources.
NetworkBK, BARD (Berkeley Digital Seismic Network and Bay Area Regional Deformation Network)
Vault/Borehole ConditionsThe vault is made of concrete, orientated north/south, and excavated into a hilltop. Approximately 1 meter of backfilled soil covers the top of the vault. The datalogger is located in an adjacent building (90' away) connected by conduits. The seismometers are thermally insulated with 4" of polyurethane foam. The accelerometer is co-located with the datalogger.

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.

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.
