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".

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".

Dies dient der Dokumentation...
und wurde dem Datensatz kurz vor dem löschen hinzugefügt.

So, wir haben uns nun geeinigt die Datensätze 353 und 709 zu löschen und Rütger legt den Datensatz komplett neu an (im Januar 2011). Bis dahin sind die Daten nicht verfügbar.

Fehlerhaft in den Daten ist zum einen die Version 353_1 (als der erste Upload von PCP). Da sind in Rütgers DB bereits falsche Tageswerte gerechnet worden.
In 353_2 sind die korrigierten Tagessätze, aber teilweise 0 statt NULL eingetragen.
Alle Daten sind fälschlicherweise ohne Quality Flag hchgeladen worden.
Die Daten in dem Attribut Ta_8m sollten eigentlich in dem Attribut Ta_2m sein.

Die Datensätze sind nach dem Löschen nicht mehr in der DB enthalten, sondern nur noch im Archiv (von gelöschten Datensätzen) verfügbar.

Außerdem werden die Datensätze 352 und 708 ebenfalls gelöscht. Sie enthalten keine Quality Flags und Rütger meint der Datensatz ist inhaltlich nicht brauchbar.

Additional info:

all A2.5 humidity/temperature files state "Ta_2m/Huma_2m" in the data column headings, but data were only taken at this height in files titled "understorey"; measurements in mid-storey and canopy vary with tree height -- please contact us in case you need to know the exact heights of midstorey/canopy measurements.
