Abstract:

Quality assessment ECSF climate station hourly data: Version 2; Dataset supersedes ver. 1 which is left for reference. Please be aware, that aggregated values may be wrong, due to the data gaps. This is especcially critical for precipitation. Variables: Ta2m =Air Temperature at 2 m (T) PCP = Precipitation at 1 m (P) Huma_2m = relative humidity at 2m (rH) Irradiation = global radiation at 2 m (gRad), widspeed. Emitted radiation, wind direction and soil-temperatures are not yet published For each variable, a measure of uncertainty is given in the original dimension. This value can be considered as the potential deviation from real conditions. Where no parallel measurements exist, the uncertainty is given as the standard deviation of that difference.

Abstract:

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

Abstract:

AMF root colonization of roots extracted from the upper soil layer (5cm) at all NUMEX plots. Roots are stained with Trypan Blue, AMF root colonization is examined by the line-intersect method.

Abstract:

Weekly time series of throughfall data from the ECSF area in the microcatchment Q2 (transects Q2.1, Q2.2 and Q2.3). Throughfall was measured weekly with 20 Hellmann-type pluviometers at each transect. The weekly replicates were volume-weighted and bulked to one sample per collecting interval and transect. Electrical conductivity and pH values were measured immediately in unfiltered aliquots in the laboratory at the ECSF.

Abstract:

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.

Abstract:

Rainfall data from the ECSF area in hourly resolution at the FN2 site located at the intersection of Camino Canal and Camino Zig-Zag. Rainfall was measured with an automatic rain gauge (Campbell ARG100, Palo Alto, USA) coupled with a HOBO H07-002-04 datalogger (Onset, Bourne, USA). Event-based recordings were aggregated to hourly data. Rain events occuring during one hour interval were aggregated to the next full hour. Data values are complete unless otherwise indicated by the data gaps below:

Data gaps during the observation period:
03/05/2012 19:02:20.5 to 17/05/2012 15:28:52.0	
20/12/2013 10:36:58.5 to 08/01/2014 15:51:25.0
28/07/2014 15:57:55.0 to 01/09/2014 17:14:27.0
06/10/2014 14:48:25.0 to 15/10/2014 18:09:26.0

Data gaps during the observation period are indicated by values = NULL. Please take these data gaps into account when aggregating precipitation values.
