Observation Values
Depending on the selected sensor configuration, the AWS330 system
produces various statistical and derived meteorological outputs.
The following tables list outputs by category.
Values with 1 minute or shorter period are regarded as instant values, that
is, they are averaged from several samples. These values are used further
to calculate statistical values for longer periods.
