Title: NGEE Arctic Tram: Visible to Near-infrared Spectral Reflectance, Barrow, Alaska, 2015-2018

Abstract

Canopy spectral reflectance collected from the NGEE-Arctic automated tram platform using a PP-Systems UniSpec-DC spectrometer. Downwelling radiance was measured using a 2 meter fiber optic cable connected to a cosine diffuser. Upwelling (i.e. reflected) radiance was measured using a 2 meter cable connected to a 12 degree field-of-view (FOV) lens. Canopy reflectance was calculated using the ratio of upwelling to downwelling radiance measured over a 99.99% reflectance Spectralon standard measured at the start of each measurement set.

NGEE Arctic Tram: HR1024i Manual Cart Canopy Spectral Reflectance, Barrow, Alaska, 2015-2017

Dataset Serbin, Shawn ; Lieberman-Cribbin, Wil ; Ely, Kim ; ...

Measurements of full-spectrum (i.e. 350-2500nm) canopy spectral reflectance along the Barrow, BEO NGEE-Arctic tram using the BNL manually operated instrument cart. Spectra was collected using the manual cart with the HR-2014i instrument and a Spectralon white plate to calibrate each measurement under variable illumination conditions. Data were collected in Barrow, Alaska during the 2015-2017 period. Additional details can be found in the resulting publications.
NGEE Arctic Tram: Overview of Tram-mounted Instruments, Co-located Data, Measurement Position, Elevation and Polygon Characterization, Barrow, Alaska, 2014-2018

Dataset Torn, Margaret ; Dafflon, Baptiste ; Dengel, Sigrid ; ...

The NGEE-Arctic Tram operated from 2014 - 2018. It was installed on the Barrow Environmental Observatory in Barrow, Alaska in late May of 2014 and operated through mid-November 2014. The subsequent 2015 through 2018 years followed a similar schedule, but with different deployment dates and data gaps, with the goal always to capture the surface dynamics of the snow melt, growing, and freeze-up seasons. This Tram overview dataset has three objectives: (1) provide new data users with a brief description of the Tram system and its research purposes; (2) provide generally useful Tram site characterization details, including measurement position groundmore »« less

NGEE Arctic Tram: Periodic Soil Moisture, Temperature, and Thaw Depth Measurements across Polygonal Tundra, Barrow, Alaska, 2014-2015

Dataset Curtis, Bryan ; Chafe, Oriana ; Peterson, John ; ...

Manual measurements of soil moisture, temperature, and thaw depth were collected in the footprint of the NGEE Arctic Tram starting 2014-07-20 and continuing through 2015-07-16. There were 10 periodic sampling events. These measurements were collected under the Tram observational platform. Probes were inserted into ground beneath the track closest to Tram sensors measurement locations at each Tram measurement position (Position # marked on the tracks). A MiniTrase Time Domain Reflectometry (TDR) instrument was used to measure volumetric water content (VWC; units = m3/m3). Soil temperature was measured with a thermocouple probe. Depth of thawed soil was measured from the topmore » of the moss layer or top of soil.« less
NGEE Arctic Leaf Spectral Absorptance, Barrow, Alaska, 2015-2016

Dataset Serbin, Shawn

Leaf level reflectance on each sample leaf was measured using a portable, full range (i.e. 0.35 to 2.5 microns) Spectra Vista Corporation (SVC) HR-1024i spectroradiometer, together with a leaf clip assembly with an internal, calibrated light source (SVC, Poughkeepsie, NY, USA). Each measurement was referenced against a LabSphere Spectralon (R) standard (LabSphere, Inc., North Sutton, NH, USA) to calculate leaf reflectance from the ratio of target and standard calibrated radiance measurements for each leaf. For each leaf, we collected two to five measurements over the leaf adaxial surface to calculate an average, depending on the leaf size and morphology. Spectralmore »« less
