Wind Measurements from Buoys (F101)

This file format is used for time-series measurements of wind and other surface meteorological parameters taken at fixed locations. The instrument arrays may be deployed on automated buoys, ships, or towers. Position, platform type and height, and instrument elevation are reported for each station. The data record comprises values of east-west (u) and north-south (v) wind components at specified date and time. Wind values may be subject to averaging or filtering and are typically reported at time intervals of 10-15 minutes. Air temperature, atmospheric pressure, and dewpoint temperature may also be reported.

File Structure:

Three 60-character records: (1) Text Record, (2) Station Header Record, and (3) Data Record.
