Data Notes and References
: See the certifications page
to learn more about the farm certifications Everyvine tracks.
: Bedrock value set to "-" is not available. Available water capacity units are cm/cm.
: Area Solar radiation has been calculated in watt hours per square meter (WH/m2)
: Topography values are averaged over the block area. Aspect is expressed in positive degrees from 0 to 359.9, measured clockwise from north.
: For use in various statistical averages, Everyvine defines the vineyard growing season as the period April 1st to October 31st.
The vineyard data presented here is most often sourced from the public data sources listed below. However, Everyvine also accepts data from vineyard owners who often have even better data they have collected themseleves.
If you have more accurate data on a vineyard go to: Data Submission page.
: Topographic and solor radiation calculations are based on 1/3 arc-second (approx. 10m) elevation models. Data provided by U.S. Geological Survey (USGS), EROS Data Center, National Elevation Dataset, http://ned.usgs.gov/
: Using monthly and annual temperature data. Calculations based on methodologies described by Gregory Jones and John Gladstones. See the following:
