- UseGlobalRad: flag indicating whether global radiation has been used.
- MaxRH: maximum relative humidity value.
- Date: indicates the day of the result.
- AveWindSpeed: mean wind speed value.
- AveRad: mean radiation value.
- VairMeasHeight: height of wind speed sensor.
- SiteLat: latitude used in the calculation.

4.2.7 Pasquill-Gifford stability class elaborated data files
The result of Pasquill-Gifford stability class calculation (§4.2.3.5) are contained in text files (*.txt). The file
naming is the same as the original files with the addition of “.SRDT.” before the extension. Following an
example of a processed:
Example 1: C20210527162230-B00- E20210528084000.SRDT.txt
Example 2: M21030052-C20210527162230-B00-E20210528084000-L20210528084000.SRDT.txt
For further information refer to §0.
The file, created by Alpha-Log as soon as all the data necessary for the calculation are available, is made up
as follows:
- the number of lines corresponds to the file originally processed
- the first column contains the same processing date and time as the source file (it considers the time
zone)
- the second column contains the numerical (non-literal) value of the calculated atmospheric stability
class (§4.2.3.5)
Following is an example of a processed file:
