Sensor Calibration and Quality Assurance Procedures
Wind Speed and Direction
Equipment:
- RM Young 05103 Wind Monitor
- NOAA Wind Monitor
Procedure:
NOAA has a suite of meteorological sensors established at the Bodega Marine Reserve. Data from these sensors can be downloaded from the internet at http://www.etl.noaa.gov/et7/data/archive/UneditedActive/.
These data are used for sensor comparison by downloading a data set from an entire day. Data are imported into Matlab, where values are converted into the same units as those logged by the BML sensor.
Since NOAA data are logged at two minute intervals, BML data are also selected at two minute increments, but data are not averaged to determine the two minute mean of the 10 second data points. They are simply instantaneous values recorded every two minutes.
The two independent data sets are compared graphically in Matlab to look for general agreement. Any gross differences are investigated further.
