Climate Parameter Quality Check for site Cajanuma Refugio

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 = 30
Global Radiation max = 1400
Soil temperature in 0cm depth max = 45
Soil temperature in 0cm depth min = 2
Soil temperature in 10cm depth max = 20
Soil temperature in 10cm depth min = 2
Soil temperature in 60cm depth max = 20
Soil temperature in 60cm depth min = 2
Air temperature in 2m max = 30
Air temperature in 2m min = 0
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 25 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 site ECSF
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 = 25
Global Radiation max = 1400
Air temperature in 2m max = 30
Air temperature in 2m min = 5
Air humidity max = 99.9
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 25 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. Relative air humidity values are corrected by a standarized method and quality flag is set to "m = manually corrected".

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

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

Hemispherical photographs taken in understorey (2m height; canopy stratum 1 - Johansson-zone 1), lower canopy (canopy stratum 3 - Johansson-zome 3) and upper canopy (canopy stratum 5 - Johansson-zone 5). Microclimate measurement at sime N-side of tree trunks are available in database, too. Camera: Nikon Coolpix 4500, lens: Nikon EZ-8 (180° fish-eye). Analysed using GLA 2.0 software (Frazer et al. 1999; Simon Fraser University, Burnaby, British Columbia, and the Institute of Ecosystem Studies, Millbrook, New York). Air temperature and relative humidity were logged at he exactly same positions on the same trees where these photos were taken (FOR816 databank files no. 525-664). We give % values (percent of canopy openness, total radiation, total (in-)direct radiation etc.) that can be transformed to radiation values using the watt/m² means given for the climate station ecsf by Paul (PhD dissertation; 2007). "Indirect" radiation means diffuse radiation.
Several dozens of additional hemispherical photographs have been taken for stratum 1  (1.3 m height: understorey) in undisturbed forest (Q2, T2, Q5 at RBSF), edges of (logging) treefall gaps (Q5) and below isolated remnant trees in a recent clearing (above the nearby village of Sabanilla), all at 2000 m but haven't been anylysed yet.
