title: Analysis of Projection Effects in OSIRIS-REx Spectral Mapping Methods

description: We search for an optimized mapping protocol and explore the characteristics of mapping remote sensing observations from a point spectrometer onto a shape model comprised of triangular facets - in the context of NASA's Asteroid Sample Return Mission: OSIRIS-REx. The shape model used was created from ground based radar observations by \citet{nolan2013shape}. Our study is conducted before the spacecraft arrives at Bennu and we use observational sequence plans of the OSIRIS-REx Visible and Infrared Spectrometer (OVIRS). We explore 6 methods of mapping data to the shape model facets, and using 3 different shape model spatial resolutions. We also attempt to increase map fidelity by increasing the observational coverage of the surface. We find that: (A) increasing shape model resolution increases mapping quality. However, once the shape model's mean facet edge length is smaller than about two fifths of the diameter of the instrument's field of view (FOV - or ``spot" size), the increase in quality tapers off and may not be worth the additional computation time. (B) The 6 mapping methods we have conceived can be broken into two categories: 1) selecting or 2) averaging observations when assigning values to each facet of the shape model. The quality differences between similar methods that average values from different spots together are insignificant, i.e. averaging, taking the median, or using the weighted average. Selecting the nearest observation to a facet best preserves an enclosed outcrop shape and signal, but averaging spots is more conservative against errors in spot positioning or signal. (C) A completely enclosed outcrop border expands into the surrounding region by 0.8-1.5 radii of the instrument's FOV after mapping. (D) Regions smaller than the instrument's FOV are present (detectable) in resulting maps, however their signal strength is reduced as a function of their size relative to the instrument FOV. We expected the sub-FOV detectability to depend on whether the contrast between the signal of the sub-FOV region and the surrounding area is greater than the instrument uncertainty. Lastly, (E) we have demonstrated that mapping quality can be improved by increasing the number of observations that cover the surface. For OSIRIS-REx, increasing the observation count requires adding together observations from the 3 dayside surveys that were obtained at different phase angles. Uncertainties due to photometric correction of these observations to a standard viewing and illumination geometry can result in systematic differences that result in map artifacts. We suggest that if combining data sets from different phase angles while mapping, averaging the spots together can help to de-emphasize any small systematic differences.

title: Polaris Project 2018: Vegetation biomass, plot characterization, point intercept, and thaw depth, Yukon-Kuskokwim Delta, Alaska.

description: This project is integrating scientific research in the Arctic with education and outreach, with a strong central focus on engaging undergraduate students and visiting faculty from groups that have had little involvement in Arctic science to date. The central element of the project is a month-long research expedition to the Yukon River Delta in Alaska. The expedition provides a deep intellectual and cultural immersion in the context of an authentic research experience that is paramount for "hooking" students and keeping them moving along the pipeline to careers as Arctic scientists. The overarching scientific issue that drives the research is the vulnerability and fate of ancient carbon stored in Arctic permafrost (permanently frozen ground). Widespread permafrost thaw is expected to occur this century, but large uncertainties remain in estimating the timing, magnitude, and form of carbon that will be released when thawed. Project participants are working in collaborative research groups to make fundamental scientific discoveries related to the vulnerability of permafrost carbon in the Yukon River Delta and the potential implications of permafrost thaw in this region for the global climate system. This data set includes vegetation biomass and elemental analysis, thaw depth, and point intercept results from the 2018 expedition.

title: Shake Table Testing of Single Rocking Wall_2 (SRW2) @ UNR

description: One of the essential considerations in seismic design of structures is to provide life safety. While the focus on life safety is to protect the buildings’ occupants, substantial economic losses ensue when an earthquake causes structural and nonstructural damage and permanent deformations. Beginning with the PREcast Seismic Structural Systems (PRESSS) program, one of the concepts that have been studied by several researchers is the use of seismic resilient systems to improve the earthquake performance of buildings beyond life safety, by mitigating structural damage. Rocking precast concrete wall is one of the practical examples originated from this concept. These walls designed with unbonded post-tensioning as primary reinforcement, which helps the system to self-center while minimizing structural damage during major seismic events. Main source of energy dissipation in Single Rocking Walls (SRW) generated from impact of the rocking body on the footing. However, in order to come up with supplemental damping for such systems, a PreWEC concept previously established. PreWEC systems are basically single rocking walls connected to side/ end steel columns using special energy dissipating oval “O” shaped mild steel connectors. These external dampers are welded to steel columns from one side and to wall steel embedment plates from the other side. While subjected to lateral loads, special, replaceable connectors placed between the wall and columns experience relative vertical displacements due to the gap opening at the base of the wall system. This results in connectors enduring large inelastic deformations and providing the necessary energy dissipation for the system.
Single Rocking Wall-2 (SRW2) consists of a concrete precast wall connected to a footing block with (6) 0.5" diameter PT strands.

title: LULUCF data based on National GHG inventories (NGHGI DB)

description: The National GHG Inventory database (NGHGI DB) presents a detailed, updated and comprehensive collection of LULUCF CO2 data, based on countries' submissions to the United Nations Framework Convention on Climate Change (UNFCCC). This file contains the main data included the paper "Carbon fluxes from land 2000-2020: bringing clarity on countries’ reporting" by Grassi et al. (2022), and aims supporting the analysis of country LULUCF data by the scientific and policy communities. For Annex I countries, data are sourced from annual GHG inventories. For non-Annex I countries, we compiled the most recent and complete information from different sources, including National Communications, Biennial Update Reports, submissions to the REDD+ (Reducing Emissions from Deforestation and Forest Degradation) framework and Nationally Determined Contributions. The data are disaggregated into fluxes from forest land, deforestation, organic soils and other sources (including non-forest land uses). The CO2 flux database is complemented by information on managed and unmanaged forest area as available in NGHGIs, in few cases using data from the Forest Resources Assessment report 2020. To ensure completeness of time series, we filled the gaps without altering the levels and trends of the country reported data. Expert judgement was applied in a few cases when data inconsistencies existed. For further methodological details, see: Grassi G, Conchedda G, Federici S, Abad Viñas R, Korosuo A, Melo J, Rossi S, Sandker M, Somogyi Z, Vizzarri M, Tubiello F.

title: Comparison of heat transfer and pressure drop correlations for evaporation of zeotropic mixtures in plate heat exchangers.

description: Zeotropic mixtures offer a possibility of optimizing heat pump cycle design by matching the working fluid temperature glide to the heat source and sink temperature profiles. Suitable heat transfer and pressure drop prediction methods are of paramount importance to evaluate the performance of plate heat exchangers (PHE) using such fluids. It is therefore relevant to evaluate the uncertainty in PHE performance estimation when zeotropic mixtures are used as working fluids. In this work, different correlations for the (Silver, 1947) and (Bell and Ghaly, 1973) method were compared to evaluate the evaporation heat transfer coefficient of mixtures of CO2 and hydrocarbons at different mass compositions and subject to heat source temperature glides of 10 K, 15 K and 20 K. Moreover, the impact of using different pressure drop models and correlations was included in the sensitivity study on the evaporator performance. Maximum deviations of 6 % and 10 % were obtained on the total heat transfer rate, depending on the prediction method chosen for the heat transfer coefficient and pressure drop, respectively. Larger discrepancies were found in the estimation of the mean UA value and total frictional pressure drops. Working fluids subject to the largest glide of 20 K resulted to be more sensitive to the choice of the prediction method. No recommended set of correlation was found, but similarities and differences between the different mixtures were identified and discussed.

title: Effects of aufeis on the structure and function of Arctic river-floodplain ecosystems, Alaska, 2016-2017

description: The goal of this study is to assess the potential effects of aufeis (i.e., river icings) on the structure and function of arctic river-floodplain ecosystems in a warming climate. Aufeis are massive accumulations of ice that are features of many arctic rivers. They form during freeze-up when thickening surface ice causes local overflows. Successive cycles of overflow result in accumulations of enormous volumes of ice, with aufeis on some Alaskan rivers attaining thicknesses of 3-5 meters, covering more than 20 square kilometers, and storing as much as 30% of the annual river discharge. Although aufeis have been studied by hydrologists and are known to be required for winter and spawning habitat for some fish, understanding of their ecology is poor. We propose that aufeis be viewed as winter oases due to their wet bases that supply water and heat to otherwise frozen habitats. Aufeis function as summer oases by providing a stable supply of water to hyporheic and downstream habitats. These data come from intensive study of the Kuparuk River Aufeis field. We collected stage and water temperature data in 50 wells that were ~1 meter deep, and stage, temperature, electrical conductivity, and dissolved oxygen data from several points in the surface channel of the aufeis field. Where we could deploy loggers, we have continuous data collection.
