Platform data

Overview

Detailed view

Orthomosaic containing Georeferenced NDVI Values from ecsf forest aquired with a low flying UAV.

Weekly time series of measured concentrations of Al, Mn, Zn, Cl, PO4-P, Total P, NH4-N, NO3-N, Total N, K, Na, Mg, Ca and Total organic C in precipitation in the ECSF area at the FN3 site on T2 near the ECSF meteorological station. The weekly time series extends between May 2000 and May 2013. Precipitation was sampled with 5 Hellmann-type collectors. Replicates were collected, volume-weighted and bulked to one sample per plot. Samples were immediately filtered (4-7 µm) in the laboratory of the ECSF and stored at -20 °C until transport in frozen state to Germany or to Switzerland for concentration measurements.

Monthly measurement of soil temperature and soil gas fluxes (CO2, N2O) in the NUMEX plots in Bombuscaro, ECSF und Cajanuma

Monthly measurements of gas fluxes were performed using static vented chambers.
Soil temperature was taken simultaneously with gas measurements.

Measurements of gas flux (CO2, CH4, N2O) in canopy soils of NUMEX plots on four dates (Sept/Nov 2011 and Jan/April 2012). Measurements were taken in 3 of the 4 NUMEX blocks at each elevation; treatments measured included C, N, NP and P.

Gas fluxes were measured by incubating intact soil cores.
Gas samples were analyzed on a gas chromatograph with a FID and ECD.
Note that the units for CO2 are mg CO2-C m-2 h-1 (not g CO2-C).

GPS points of the ECSF_PINOS PLOT, original files and corrected with the NCI GPS data.

Arbuscular mycorrhizal root colonization (%), colonized root length (cm/cm³) and fine root parameters in response to nutrient additions (N, P and NP) are reported. Samples were taken in October 2010 at the NUMEX plots at 2000m.

Weekly time series of precipitation data from the ECSF area at the measuring station FN3 located on T2 near the ECSF meteorological station. Precipitation was measured with 5 Hellmann-type pluviometers. The resulting weekly replicates of precipitation were volume-weighted and bulked to one sample per collecting interval. Electrical conductivity and pH values were measured immediately in unfiltered aliquots in the laboratory at the ECSF.

The table is a  list of arbuscular mycorrhizal fungi with their host plants. The sequences are deposited in the NCBI GenBank.

Due to technical problems the former weather station ECSF (established 1998) was shut down in 2010. At the same time a new weather station called "Climate Station ECSF established 2010" was installed 3m beside the former ECSF weather station on the same measuring plot.

The data are quality checked by a standardised method.

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".
