This field holds a 1 (TRUE) or 0 (FALSE) depending on whether the station in question is located at an airport. [UNITS: none, FIELD: One digit integer]
This information was determined by using Google maps.
This field holds a 1 (TRUE) or 0 (FALSE) depending on whether the station in question is located on grazing land. [UNITS: none, FIELD: One digit integer]
Aerial and satellite imagery were manually referenced to create this designation
This field holds a 1 (TRUE) or 0 (FALSE) depending on whether soil moisture has been manually sampled at the station. [UNITS: none, FIELD: One digit integer]
This value is determined by the GPS reflections group.
This field holds a 1 (TRUE) or 0 (FALSE) depending on whether vegetation water content has been sampled at the station. [UNITS: none, FIELD: One digit integer]
This field holds a 1 (TRUE) or 0 (FALSE) depending on whether the station in question has meteorological sensors. [UNITS: none, FIELD: One digit integer]
This information was provided by http://pbo.unavco.org.
This field holds the average MP1 value for the station. [UNITS: none, FIELD: Decimal with three degrees of precision]
This information was calculated by the GPS Reflections team. Typically it is based on a five year average after snow-contaminated data have been removed.
This field holds a value representing the station correlation to NDVI. [UNITS: none, FIELD: Decimal with two degrees of precision]
This value was calculated from a comparison of five years of NDVI data and MP1rms data made by the GPS reflections team. Both time series were cleared for snow. Correlations were calculated for lags between 0 to 5 weeks, and the best correlation is reported.
This field holds the maximum observed normalized difference vegetation index (NDVI) value for the station in question. [UNITS: none, FIELD: Decimal with three degrees of precision]
This information was calculated by the GPS Reflections group, reporting the average of the 95th percentile.
This field holds the minimum observed normalized difference vegetation index (NDVI) value for the station in question. [UNITS: none, FIELD: Decimal with three degrees of precision]
This information was calculated by the GPS Reflections group, reporting the average of the 5th percentile.
This field holds a 1 (TRUE) or 0 (FALSE) depending on whether the station in a Plate Boundary Observatory (PBO) site. [UNITS: none, FIELD: One digit integer]
This information was provided by http://pbo.unavco.org.
This field holds a 1 (TRUE) or 0 (FALSE) depending on whether the station in question is co-located with a SNOTEL station. [UNITS: none, FIELD: One digit integer]
The GPS reflections group calculated which GPS sites were within 25 km of SNOTEL sites.
This field holds the distance between the co-located SNOTEL station and the station in question. [UNITS: km, FIELD: Decimal with one degree of precision]
This distance was calculated by the GPS reflections group based on station locations provided by SNOTEL.
This field holds the two-character abbreviation for the state where the station is located. [UNITS: none, FIELD: Two character text] Special Note: CN/CS = CA North/South
This information was provided by http://pbo.unavco.org.
This field holds modeled annual snow water equivalent (SWE) at the station. [UNITS: mm, FIELD: Decimal with one degree of precision]
Armstrong, R.L., M.J. Brodzik, K. Knowles, and M. Savoie, Global monthly EASE-Grid snow water equivalent climatology. Boulder, CO: National Snow and Ice Data Center. Digital media. Available at http://nsidc.org/data/nsidc-0271.html, 2005.
This field holds a value representing the correlation between MP1RMS to NLDAS average temperature. [UNITS: none, FIELD: Decimal with two degrees of precision]
This information was calculated by the GPS reflections group.
This field holds a 1 (TRUE) or 0 (FALSE) depending on whether the station produces a vegetation water content product. [UNITS: none, FIELD: One digit integer]
Reflected GPS signals are sensitive to snow, soil moisture, and vegetation. The PBO H2O Data Portal makes hydrologic products based on GPS data available directly through your web browser.
