Description: | Wind speed calibration factors were reversed between wind speed sensors 1 (upper) and 2
(lower). Results in less than 1% error, but correction factors may be used.
To correct wind speed #1 (upper) add 0.03 m/s.
To correct wind speed #2 (lower) subtract 0.03 m/s. |

Description: | On April 1, 2001 at 00:00:00 new data header with consistent variable naming conventions,
etc were to be used for all sites, all data streams. At the TWP sites the time of the
movement to the new convention did not occur precisely at 00:00:00. The following data
files contain between 40 seconds and 20 minutes of data from 4/1/02 in the old format. The
delayed format change did not affect data quality in any way.
