Attention: The old weatherstation was replaced by a new one on 9.6.2010

The data are quality checked by a standardised method.

Climate Parameter Quality Check for site El Tiro
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
Rad Max = 1350
tsoil0cm max = 30
tsoil0cm min = 2
tsoil10cm max = 20
tsoil10cm min = 9
Tsoil60cm max = 15
tsoil60ccm min = 7
Air temperature in 2m max = 25
Air temperature in 2m min = 3
Air humidity max = 100
Air humidity min = 10


3. 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.

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".

Climate Parameter Quality Check for site Vilcabamba

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 = 10
Global Radiation max = 1400
Soil temperature in 0cm depth max = 45
Soil temperature in 0cm depth min = 5
Soil temperature in 10cm depth max = 35
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 = 35
Air temperature in 2m min = 10
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".
