Northern and central Walker Lane horizontal velocities in North America and Sierra Nevada reference frames.

The data in this file contains east and north velocities covering the northern and central sections of the Walker Lane, USA. The velocities were obtained from GPS time series, available at Nevada Geodetic Laboratory (NGL): http://geodesy.unr.edu/NGLStationPages/gpsnetmap/GPSNetMap.html (24 hour final solutions). The position time series were manually screened and corrected for offsets, and a local common-mode filter was applied following the methodology of Kreemer & Blewitt (2021, https://doi.org/10.1007/s00190-020-01466-5). Velocities in the North America frame were obtained using MIDAS, a robust median trend estimator (Blewitt et al., 2016,  https://doi.org/10.1002/2015JB012552). Two sets of stations were used to rotate the velocities into the Sierra Nevada frame: CAOV, CAPV, P140, P276, P310 for the northern section and CMBB, P245, P305, P308, P512 for the central section.

The file contains the following columns:

sta: station ID

lon: longitude of station (decimal degree)

lat: latitude of station (decimal degree)

ve_NA: east velocity in North America frame (mm/yr)

vn_NA: north velocity in North America frame (mm/yr)  

ve_SN: east velocity in Sierra Nevada frame (mm/yr)  

vn_SN: north velocity in Sierra Nevada frame (mm/yr)  

region: denotes whether the set of stations used to rotate the velocities into the Sierra Nevada frame are located in the northern (N) or central  (C) Walker Lane

sve: east velocity uncertainty (mm/yr)

 svn: north velocity uncertainty (mm/yr)

network: who operates the station
