speed is measured 10 meters above the ground.
The two temperatures are measured at a height of 2 and 10 meters.
Night and day are determined by the measurement of solar radiation. Below 3 W/m

is considered
night, while above day.

Gifford (P-G) Stability Categories (October 1993) and Meteorological Moni-toring Guidance for Regulatory
Modeling Applications - EPA (February 2000).
To access the configuration:
1. From section Estensions,
select Calculation Modules.

3. Set Enable Pasquill-Gifford
elaboration to Yes.
Then proceed to fill in the required fields based on the measurements available on the data logger.
The elaboration results are stored in a specific file in ASCII text format (§) and sent to remote reception
systems, as already provided for the statistical elaborated data normally produced by the data logger.
4.2.3.6 Dew point temperature
The calculation of the dew point temperature is based on UNI EN ISO 7726. It requires measurements of
temperature and relative humidity of the air.
