  • This data package contains net photosynthesis rates and methanol and isoprene leaf emissions as a function of light, temperature, and leaf age. Data was collected from the species V. guianensis in Manaus, Brazil, and is used in the publication "Methanol and Isoprene Emissions from the Fast Growing Tropical Pioneer Species Vismia guianensis (Aubl.) Pers. (Hypericaceae) in the Amazon Basin." See the below field, Dataset References, for the full citation.

  • Fine-root length and diameter measured from minirhizotron images collected at AmazonFACE plots, Manaus, Brazil, from November 2016 through December 2017. calculated values of root productivity, mortality, and standing crop, and associated files necessary for converting length and diameter to biomass.

  • CO2 response (ACi curves) gas exchange of sunlit canopy leaves of GUATDU, MICOBO, TERMAM and VOCHFE species from PA-SLZ, February 2017. CO2 response measured on young, mature and old leaves collected before dawn on 3 days. Fitted Vc,max and Jmax photosynthetic parameters derived from measured data. This data was collected as part of the 2017 BNL–STRI leaf traits by age campaign. See related datasets for further sample details, leaf water potential, leaf spectra, diurnal gas exchange, sap flow, LMA and leaf chemistry.

  • We used entropy and wavelet techniques to identify temporal variability in geochemical constituents and their controls along three transects within a contaminated floodplain system near Rifle CO. The objectives of this study were to: (1) identify hot moments of conservative and redox sensitive species as short time-periods with disproportionally high levels of concentration, and (ii) associate the transport and/or biogeochemical factors controlling this temporal variability. This data package includes tables from Arora et al. 2016a: Identifying geochemical hot moments and their controls on a contaminated river floodplain system using wavelet and entropy approaches, Environmental modelling & software, 85, 27-41. In particular, files include sampling frequency for geochemical data at the Rifle site, and results of entropy analysis.

  • Leaf water potential of sunlit canopy leaves of APEIME, GUATDU, MICOBO, TERMAM, VIROSP and VOCHFE species from PA-SLZ, February 2017. Leaf water potential measured on young, mature and old leaves collected before dawn and around midday on 21 Feb and 22 Feb. This data was collected as part of the 2017 BNL–STRI leaf traits by age campaign. See related datasets (existing and future) for further sample details, leaf spectra, sap flow, LMA, gas exchange and leaf chemistry.

  • Raw leaf surface temperature data from K34 tower site on a plateau near Manaus, Brazil including automated and manually collected time series data on leaf surface temperature (thermocouples, IR radiometer, thermocamera). Leaf surface temperature (LST) is determined throughout diurnal periods using individual type T thermocouples (Omega Engineering) on 8 individual leaves of a single tree. Mature leaves at the same height and general area near the tower are selected. LST measurements every 15 s are recorded on a field portable self-powered data logger (OM-CP-OCTTEMP-A, Omega Engineering). Measurements are stopped in the case of a storm or rain which can remove the attached thermocouple wires from the leaf due to large wind-driven branch movements. See dataset references for associated metadata package. This dataset replaces the leaf surface temperature data of two retired packages, http://dx.doi.org/10.15486/ngt/1507764 and http://dx.doi.org/10.15486/ngt/1507767

  • Heat was used as a tracer to quantify seasonal changes in vertical Darcy velocity through the streambed at three different locations about Meander A of East River, Colorado. The file Raw_Temp.csv represents raw temperature data (in degrees Celsius) collected from the three locations, A, B, and C, at depths of 5, 10, 20, and 35 cm below the sediment-water interface. Darcy velocity estimates were calculated from these data using 1DTempPro and are shown in 1DTempPro_estimates.csv file. Positive values represent upwelling conditions, while negative values indicate downwelling conditions.
