Additional info:

All A2.5 humidity/temperature files state "Ta_2m/Huma_2m" in the data column headings, but data were only taken at 2 m height in files titled "understorey"; measurement heights in mid-storey (lower canopy) and overstorey (upper canopy) vary with tree height -- please contact us in case you need to know exact heights above ground/below canopy of measurements taken in forest canopy or within the crowns of isolated trees in pastures. Hemispherical photographs taken right above the data loggers and the resulting transmission/canopy openness values are also available upon request.

Climate Parameter Quality Check for site El Libano

Checking modules:

1. Does a value exist?
Quality flag is set to 
"d = missing"

2. Checking of site specific threshold value.
If the value is not inbetween the thresholds the quality flag is set to "c = out of range":
Windspeed max = 5
Global Radiation max = 1400
Soil temperature in 0cm depth max = 45
Soil temperature in 0cm depth min = 5
Soil temperature in 10cm depth max = 25
Soil temperature in 10cm depth min = 10
Soil temperature in 60cm depth max = 25
Soil temperature in 60cm depth min = 10
Air temperature in 2m max = 30
Air temperature in 2m min = 5
Air humidity max = 100
Air humidity min = 10

3. Checking the plausibility of air temperature and air humidity within the measurement intervals by comparing the previous and current values.
If the temperature amplitude is higher then 10°C and humidity amplitude is higher than 30% the plausibility of this variation is checked by comparing to the variation of the other parameter.  
The quality flag is set to "e = variation implausible".

4. Precipitation check
If precipitation is more than 40 mm then quality flag is set to "c = out of range"
If precipitation is more than 15 mm and air temperature increases more than 0.2 °C inbetween a temporal interval then quality flag is set to "e = variation impossible".

5. Wind direction is not quality checked and flag is set to "nqc = not quality checked"

All other values are set to "a = valid".

Climate Parameter Quality Check for Cajanuma Forest
Checking modules:

1. Does a value exist?
Quality flag is set to 
"d = missing"

2. Checking of site specific threshold value.
If the value is not inbetween the thresholds the quality flag is set to "c = out of range":
Windspeed 8m max = 15
windspeed 2m max = 4
Rad Max = 500
graddown max = 50
Air temperature in 2m max = 20
Air temperature in 2m min = 0
Air temperature in 30cm max = 20
Air temperature in 30cm min = 0
Air humidity in 2m max = 100
Air humidity in 2m min = 10
Air humidity in 30cm max = 100
Air humidity in 30cm min = 10



3. Wind direction and soil moistures are not quality checked and flag is set to "nqc = not quality checked"

4. Soil moisture is not quality checked

All other values are set to "a = valid".
