1. Range Check
A Value is ok
if
"lower range" <= Value <= "upper range"
If the Value is out of this range, it is set to "Measurement
Error / Missing" Value.
2. Clipping
if a Value
< "lower clip" then this particular value is set to
Value = lower Clip
e.g. to set a shortwave radiation of -1.3 Wm-2 during night
(instrument offset) back to 0.
if a Value
> "upper clip" then this particular value is set to
Value = upper clip
e.g. to set a relative humidity of 105% back to 100%.
The range check is done before clipping.
