Campbell summary data

Sensor elevations are height above the ground. The ground is approximately 6.5 meters above sea level

Most of the data parameters include valus for the mean and median value as well as the standard deviation of the variable. The table below shows the field name suffix used to differentiate amoung the different values:

Field name	Description
_mean	The mean value of the variable over the averaging period
_m50	The median value of the variable over the averaging period
_std	The standard deviation of the variable over the averaging period
_length	The number of valid data points collected over the averaging period
