Standards

  • Three types recorded: speed, direction, and gusts.
  • Instantaneous velocities are sampled every 30 seconds.
  • Wind direction is recorded in degrees from true north [5.5.1].
  • Average wind direction and speed is determined by averaging the values over a 2-minute period [5.4].
  • Wind gusts are the maximum instantaneous speed in the past 10 minutes [5.5.4].

Documents

Federal Meteorological Handbook

Indiana State Climate Office

METAR

  • http://metar.noaa.gov/ - METAR is the international standard code format for hourly surface weather observations which is analogous to the SA coding currently used in the US.

World Meteorological Organization

Databases

Indiana Climate Data Access

Farmland

Damping Techniques

  • The mode is consisidered the prevailing wind direction.
  • Dividing each recording into a north-south and east-west vector, averaging them, and then reassembling the vectors.
