Platform data

Overview

Detailed view

Orthomosaic containing georeferenced NDVI Values from Bombuscaro forest aquired with a low flying UAV.

Weekly time series of water fluxes, electrical conductivity, pH values and 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 throughfall in Bombuscaro at 1000 m a.s.l. in NUMEX Plot 12 (control). The weekly time series extends between March 2018 and December 2019. Throughfall was sampled weekly with 20 Hellmann-type collectors. Replicates were collected, volume-weighted and bulked to one sample per plot and sampling period. Electrical conductivity and pH values were measured immediately in unfiltered aliquots in the laboratory at the ECSF. Samples were filtered (4-7 µm) in the laboratory of the ECSF and stored at -20 °C until transport in frozen state to Germany for concentration measurements.

Weekly time series of water fluxes, electrical conductivity, pH values and 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 from the Bombuscaro site at 1000 m a.s.l. located at the climate station. The weekly time series extends between March 2018 and December 2019. Precipitation was sampled with 5 Hellmann-type collectors. Replicates were collected, volume-weighted and bulked to one sample per plot. Electrical conductivity and pH values were measured immediately in unfiltered aliquots in the laboratory at the ECSF. Samples were filtered (4-7 µm) in the laboratory of the ECSF and stored at -20 °C until transport in frozen state to Germany for concentration measurements.

For the seedling transplantation experiment conducted in NUMEX plots in Bombuscaro using as a target species Pouteria torta for monitoring during one year the effects of fertilization in a common species. This data set correspond to the initial measurements of the experiment

Corrected plots from Bombuscaro, ECSF, Cajanuma, Zamora and Laipuna region as shape files.

Analyses if morphological and physiological attributes of seedlings from the two most common species in NUMEX experiment at the three elevations. Changes in this attributes are altered by nutrient availability in this case fertilization might showed specific limitation for N or P.

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.

Ongoing data collected from Bombuscaro Thies climate station.

Raw data, initial visual control only. Use data with great care, errors might be included.

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).
