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.

Long term series of weekly total of incident pricipitation (mean of 5 replicates), pH and EC of bulked PCP samples.
NOTE: PCP volumes from > April 2003 need to be quality checked (rate 50 to 20). 

Taken from Fleischbein et al. (2005):
Rainfall interception in forests is influenced by properties of the canopy that tend to vary over small distances. Our objectives were: (i) to determine the variables needed to model the interception loss of the canopy of a lower montane forest in south Ecuador, i.e. the storage capacity of the leaves S and of the trunks and branches S-t, and the fractions of direct throughfall p and stemflow p(t); (ii) to assess the influence of canopy density and epiphyte coverage of trees on the interception of rainfall and subsequent evaporation losses.
The study site was located on the eastern slope of the eastern cordillera in the south Ecuadorian Andes at 1900-2000 m above sea level. We monitored incident rainfall, throughfall, and stemflow between April 1998 and April 2001. In 2001, the leaf area index (LAI), inferred from light transmission, and epiphyte coverage was determined.

The mean annual incident rainfall at three gauging stations ranged between 2319 and 2561 mm. The mean annual interception loss at five study transects in the forest varied between 591 and 1321 mm, i.e. between 25 and 52% of the incident rainfall. Mean S was estimated at 1(.)91 mm for relatively dry weeks with a regression model and at 2(.)46 mm for all weeks with the analytical Gash model; the respective estimates of mean S-t were 0(.)04 mm and 0(.)09 mm, of mean p were 0(.)42 and 0(.)63, and of mean pt were 0(.)003 and 0(.)012. The LAI ranged from 5(.)19 to 9(.)32. Epiphytes, mostly bryophytes, covered up to 80% of the trunk and branch surfaces. The fraction of direct throughfall p and the LAI correlated significantly with interception loss (Pearson's correlation coefficient r = -0(.)77 and 0(.)35 respectively, n = 40). Bryophyte and lichen coverage tended to decrease S, and vascular epiphytes tended to increase it, although there was no significant correlation between epiphyte coverage and interception loss. Our results demonstrate that canopy density influences interception loss but only explains part of the total variation in interception loss. Copyright (c) 2004 John Wiley & Sons, Ltd.

updating and correcting dataset 709. Please contact data creator for more information

We sampled streams in two pasture catchments (ECQC and ECQP), two entirely forested streams (Quebrada Milagro ECQM and Quebrada Ramon ECQR), two disturbed catchments (Quebrada Zurita ECQZ and Quebrada Navidades ECQN) and three times in the main San Francisco river: once, before the compuerta (ECFH), once down at the ECSF station (ECSF) and once at the Planta (ECPL). We also samples rain once in a while (own collector right at the station).

For more information on the exact coordinates of the station and the detection limits and analysis methods please contact us. 
It is best to be sent a map with the locations of the sampling stations on it because the geographical coordinates sometimes are too imprecise and are then on solid ground and not in the river..
