End-of-Winter Snow Depth, Temperature, Density, and SWE Measurements at Teller Road Site, Seward Peninsula, Alaska, 2019

| Summary: | Measurements of end-of-winter snow properties were collected at the NGEE Arctic TellerRoad Site at mile marker 27 (TL_MM27) from March 31 to April 7, 2019. This dataset contains three *.csv data files of spatiallydistributed values of snow depth, snow water equivalent (SWE), and temperature at the snow surface and at the bottom of the snowpack. Data were collected toward the end of the winter season from late March to early April, when the snowpack would be near itsmaximum.ASnow-Hydro MagnaProbe ( http://www.snowhydro.com/products/column2.html ) was used to improve collectionefficiency and enhance spatial coverage. A user guide included as a *.pdf.This dataset is a continuation of the previous end-of-wintersnowsurveysconducted attheTeller RoadSitein 2016-2018 (Wilson et al., 2020; https://doi.org/10.5440/1592103 ). The Next-Generation Ecosystem Experiments: Arctic (NGEE Arctic), a research effort to reduce uncertainty in Earth System Models by developing apredictiveunderstanding ofcarbon-richArcticecosystemsandfeedbackstoclimate. NGEEArcticwas supportedbytheDepartmentofEnergy?s OfficeofBiologicalandEnvironmentalResearch. The NGEE Arctic project had two field research sites: 1) located within the Arcticpolygonal tundra coastal region on the Barrow Environmental Observatory (BEO) and theNorth Slope near Utqiagvik (Barrow), Alaska and 2) multiple areas on the discontinuouspermafrostregion of theSewardPeninsula north ofNome,Alaska. Through observations, experiments, and synthesis with existing datasets, NGEE Arcticprovided an enhanced knowledge base for multi-scale modeling and contributed toimproved process representation at global pan-Arctic scales within the Department ofEnergy?s Earth system Model (the Energy Exascale Earth System Model, or E3SM), and specifically withintheE3SMLand Modelcomponent(ELM). |
