title:  Non-additivity of the mid-latitude circulation response to regional Arctic temperature anomalies: the role of the stratosphere: Data

description: Previous studies have documented the impact of the Arctic sea ice loss and associated warming on the mid-latitude weather and climate, especially the influence of sea ice retreat over the Barents-Kara Sea on the North Atlantic and Europe regions. However, less attention has been given to other geographical locations over the Arctic, and to the linear additivity of the circulation response to regional Arctic sea ice loss and temperature anomalies. Using a simplified dry dynamical core model, we demonstrate that, responses to regional Arctic temperature anomalies over the Barents-Kara Sea, Baffin Bay-Davis Strait-Labrador Sea and East Siberia-Chukchi Sea, separately, cause similar equatorward shift of the tropospheric jet, but different stratospheric polar vortex responses. Furthermore, responses to regional Arctic temperature anomalies are not linearly additive, and the residual resembles a positive Northern Annular Mode-like structure. Additional targeted experiments highlight the stratospheric influence in the non-additivity of the mid-latitude tropospheric response. This processed data is for peer-review, we will share a new version of the data more openly upon publication of this study.

title:  On the suitability of second-order accurate finite-volume solvers for the simulation of atmospheric boundary layer flow

description: The present work analyzes the quality and reliability of an important class of general-purpose, second-order accurate finite-volume (FV) solvers for the large-eddy simulation of a neutrally stratified atmospheric boundary layer (ABL) flow. The analysis is carried out within the OpenFOAM® framework, which is based on a colocated grid arrangement. A series of open-channel flow simulations are carried out using a static Smagorinsky model for subgrid scale momentum fluxes in combination with an algebraic equilibrium wall-layer model. The sensitivity of the solution to variations in numerical parameters such as grid resolution (up to 1603 control volumes), numerical solvers, and interpolation schemes for the discretization of nonlinear terms is evaluated and results are contrasted against those from a well-established mixed pseudospectral–finite-difference code. Considered flow statistics include mean streamwise velocity, resolved Reynolds stresses, velocity skewness and kurtosis, velocity spectra, and two-point autocorrelations. A quadrant analysis along with the examination of the conditionally averaged flow field are performed to investigate the mechanisms responsible for momentum transfer in the flow. It is found that at the selected grid resolutions, the considered class of FV-based solvers yields a poorly correlated flow field and is not able to accurately capture the dominant mechanisms responsible for momentum transport in the ABL. Specifically, the predicted flow field lacks the well-known sweep and ejection pairs organized side by side along the cross-stream direction, which are representative of a streamwise roll mode. This is especially true when using linear interpolation schemes for the discretization of nonlinear terms. This shortcoming leads to a misprediction of flow statistics that are relevant for ABL flow applications and to an enhanced sensitivity of the solution to variations in grid resolution, thus calling for future research aimed at reducing the impact of modeling and discretization errors.

title:  Seasonal dynamics of vegetation over the past 100 years inferred from tree rings and climate in Hulunbei'er steppe, northern China: Supplementary data

description: Supplementary data: The relationship between monthly vegetation cover anomalies and climate in the Hulunbei'er steppe were studied through analyzing the relationship between regional normalized difference vegetation index (NDVI) and climatic variables, and NDVI and tree-ring width during the growing season (May–October). The local moisture (dry/wet) and temperature (cold/warm) variations largely affected the vegetation cover and the radial growth of Mongolian pines (Pinus sylvestiris Linnaeus var. mongolica Litvinov) in the steppe. Monthly precipitation and Palmer drought severity index (PDSI) data from the previous to the current growing seasons were positively correlated to regional vegetation cover and radial growth of Mongolian pines; however, negative correlations were found between temperature and vegetation variables. A reconstruction of monthly vegetation cover dynamics for the growing season was created and spans 116 years (from 1891 to 2006). The results show that the total numbers of anomalies for dense and sparse seasonal vegetation cover is 22 years over the 116 year record; about 5–7 relatively dense or sparse periods; and ∼2–8 years significant periodicities (p &gt; 0.05). Linkages to the Pacific Ocean and Arctic Ocean regimes were also detected.

title:  Sensitivity of tropospheric ozone over the Southeast USA to dry deposition: Data

description: Dry deposition (DD) is a major loss process for tropospheric ozone and some reactive nitrogen and carbon precursors. We investigate the response of summertime ozone and its production chemistry over the Southeast United States (USA) to variability in this sink. Turning off DD of oxidized nitrogen, ozone, or all species over the USA in the GFDL AM3 model increases regional mean surface ozone by 5, 18 or 25 ppb, respectively. Additional sensitivity simulations demonstrate that, assuming linearity, surface ozone has a similar sensitivity to ozone DD as to NOx emissions. Trends in ozone production efficiency derived from observed relationships between ozone and precursor oxidation products may not solely reflect precursor emission changes if ozone DD varies (e.g. with meteorology). We conclude that DD variability merits consideration when interpreting observed ozone trends. Quantifying the impact of changes in sinks versus sources will require long-term DD measurements across the region of interest.

title:  Silk Road Health Project mobility-migration-hiv SPSS data

description: [Objectives] We examined whether mobility, migrant status, and risk environments are associated with sexually transmitted infections (STIs) and HIV risk behaviors (e.g. sex trading, multiple partners, and unprotected sex). [Methods] We used Respondent Driven Sampling (RDS) to recruit external male migrant market vendors from Kyrgyzstan, Uzbekistan, and Tajikistan as well internal migrant and non-migrant market vendors from Kazakhstan. We conducted multivariate logistic regressions to examine the effects of mobility and migration status and risk environment on STIs and sexual risk behaviors. [Results] Mobility was associated with increased risk for biologically-confirmed STIs, sex trading, and unprotected sex among non-migrants, but not among internal or external migrants. Condom use rates were low among all three groups, particularly external migrants. Risk environment factors of low-income status, debt, homelessness, and limited access to medical care were associated with unprotected sex among external migrants. [Conclusion] Study findings underscore the role mobility and risk environments play in shaping HIV/STI risks. They highlight the need to consider mobility in the context of migration status and other risk environment factors in developing effective prevention strategies for this population.

title:  Simulating Gas Inflow at the Disk-Halo Interface

description: The interaction between inflowing gas clouds and galactic outflows at the interface where the galactic disk transitions into the circumgalactic medium is an important process in galaxy fueling, yet remains poorly understood. Using a series of tall-box hydrodynamic ENZO simulations, we have studied the interaction between smooth gas inflow and supernovae-driven outflow at the disk-halo interface with pc-scale resolution. Please see Melso et al. 2019 for details. Here we have uploaded movies for the BURST50, BURST100, and IMD10 simulations. They are also embedded in-text in the Appendix of the ApJ publication.

title:  Spatiotemporal controls on observed daytime ozone deposition velocity over Northeastern U.S. forests during summer: Data and analysis scripts

description: Spatiotemporal variability in ozone dry deposition is often overlooked despite its implications for interpreting and modeling tropospheric ozone concentrations accurately. Understanding the influences of stomatal vs. nonstomatal deposition processes on ozone deposition velocity is important for attributing observed changes in the ozone depositional sink and associated damage to ecosystems. Here, we aim to identify the stomatal versus nonstomatal deposition processes driving observed variability in ozone deposition velocity over the northeastern United States during June-September. We use ozone eddy covariance measurements from Harvard Forest in Massachusetts, which span a decade, and from Kane Experimental Forest in Pennsylvania and Sand Flats State Forest in New York, which span one growing season each, along with observation-driven modeling. Using a cumulative precipitation indicator of soil wetness, we infer that high soil uptake during dry years and low soil uptake during wet years may contribute to the twofold interannual variability in ozone deposition velocity at Harvard Forest. We link stomatal deposition and humidity to variability in ozone deposition velocity on daily timescales. The humidity dependence may reflect higher uptake by leaf cuticles under humid conditions, noted in previous work. Previous work also suggests uptake by leaf cuticles may be enhanced after rain, but we find that increases in ozone deposition velocity on rainy days are instead mostly associated with increases in stomatal conductance. Our analysis highlights a need for constraints on sub-seasonal variability in ozone dry deposition to soil and fast in-canopy chemistry during ecosystem stress.

title:  Spherical Indentation Equilibrium Mechanical Data of Nonpregnant Human Cervical Tissue

description: These files contain experimental data from a mechanical study evaluating the four-level, ramp-hold tissue material response to spherical indentation on human cervical samples for 52 locations of 13 cervical samples from 7 cervices. The data in this file correspond to the manuscript entitled, "Anisotropic Material Characterization of Human Cervix Tissue based on Indentation and Inverse Finite Element Analysis", to be published in the ASME Journal of Biomechanical Engineering in 2019 in the special issue honoring Y.C. Fung’s 100th Birthday. The manuscript is co-authored by Lei Shi, Wang Yao, Yu Gan, Lily Zhao, W. Eugene McKee, Joy Vink, Ronald Wapner, Christine Hendon, and Kristin Myers. The RawData folder contains .csv files corresponding to each tested location. Each file includes the experimental indentation equilibrium force and strain data – see manuscript for methods. The name of the file indicates the sample ID, which includes the gestation status (NP = nonpregnant), the sample number identifier, the location in the cervix (EO = External OS & IO = Internal OS), and the indentation location on the sample (A, P, L, and R = Anterior, Posterior, Left, and Right, respectively). For example, NP1-IO_A corresponds to the experimental data for nonpregnant sample #1 internal os in the anterior quadrant. In these files, the columns correspond to: the indentation depth [mm], Lagrangian strain exx, eyy, and exy, and force [N] of the tests. The force and depth are recorded from a universal testing machine and the exx, eyy, and exy are calculated via Vic2D (Correlated Solutions Inc.) using the figures recorded using VicSnap (Correlated Solutions Inc.). The strain data are taken directly under the indenter tip, where the coordinate system is rotated such that exx and eyy align with the circumferential and radial directions of the cervical slices, respectively. In the manuscript they correspond to exx_EXP, eyy_EXP, and exy_EXP.

title:  State-dependent function of neocortical chandelier cells

description: Chandelier (axo-axonic) cells are a distinct group of GABAergic interneurons which innervate the axon initial segments of pyramidal cells. However their circuit role, and the function of their clearly defined anatomical specificity, remains unclear. Recent work has demonstrated that chandelier cells can produce depolarizing GABAergic PSPs, occasionally driving postsynaptic targets to spike. On the other hand, other work suggests that ChCs are hyperpolarizing and thus may have a purely inhibitory role. These disparate functional effects may reflect heterogeneity amongst ChCs. Here, using in vitro brain slices from transgenic mouse strains we first demonstrate that across different neocortical areas and genetic backgrounds, upper layer 2/3 ChCs belong to a single electrophysiologically and morphologically defined population, extensively sampling layer 1 inputs with asymmetric dendrites. Consistent with being a single cell type, we find electrical coupling between ChCs. We then investigate the effect of chandelier cell activation on pyramidal neuron spiking in several conditions, ranging from the resting state to stimuli designed to approximate in vivo membrane potential dynamics. We find that under quiescent conditions, chandelier cells are capable of both promoting and inhibiting spike generation. However, during in vivo-like membrane potential fluctuations, the dominant postsynaptic effect was inhibition. Thus, neocortical chandelier cells, even from within a homogeneous population, appear to play a dual role in the circuit, helping to activate quiescent pyramidal neurons, while at the same time inhibiting active ones.

title:  Storage ring cross section measurements for electron impact ionization of Fe⁸⁺: Data

description: We have measured electron impact ionization (EII) for Fe⁸⁺ forming Fe⁹⁺ from below the ionization threshold to 1200 eV. These measurements were carried out at the TSR heavy ion storage ring. The objective of using a storage ring is to store the ion beam initially so that metastable levels decay, thereby allowing for measurements on a well-defined ground-level ion beam. In this case, however, some metastable levels were too long lived to be removed. We discuss several methods for quantifying the metastable fraction, which we estimate to be ~30%–40%. Although metastables remain problematic, the present storage ring work improves upon other experimental geometries by limiting the metastable contamination to only a few long-lived excited levels. We discuss some future prospects for obtaining improved measurements of Fe⁸⁺ and other ions with long-lived metastable levels. In the attached file, the first column is collision energy in eV, the second column is cross section in cm^-2, and the last column gives the statistical uncertainty.

title:  Strategic Applications of Tandem Reactions in Complex Natural Product Synthesis: Rapid Access to the (Iso)Cyclocitrinol Core: Spectral Analysis

description: This is the spectral analysis accompanying a thesis that describes the efforts of Professor James Leighton and myself toward the synthesis of the tetracyclic core of a class of steroidal natural products known as the cyclocitrinols. Our initial work in this area was performed on racemic model systems in order to validate our ring contraction-Cope rearrangement strategy. Novel chemistry was then identified to access the functionalized core in enantio-enriched form. Finally, in line with our efforts to probe the transition state of our key tandem Claisen-Cope reaction, additional substrates were prepared supporting our proposed transition state and improving the efficiency of this transformation.

title:  Supplemental Data: Climatology, variability and trends in United States vapor pressure deficit, an important fire-related meteorological quantity

description: Unlike the commonly used relative humidity, vapor pressure deficit (V P D), is an absolute measure of the difference between the water vapor content of the air and its saturation value and an accurate metric of the ability of the atmosphere to extract moisture from the land surface. V P D has been shown to be closely related to variability in burned forest area in the western United States. Here the climatology, variability and trends in V P D across the U.S. are presented. V P D reaches its climatological maximum in summer in the interior southwest U.S. due to both high temperatures and low vapor pressure under the influence of the northerly, subsiding eastern flank of the Pacific subtropical anticyclone. Maxima of variance of V P D are in the southwest and southern Plains in spring and summer and are to a large extent driven by temperature variance but vapor pressure variance is also important in the southwest. La Niña-induced circulation anomalies cause subsiding, northerly flow that drive down actual vapor pressure and increase saturation vapor pressure in fall through spring. High spring and summer V P D can also be caused by reduced precipitation in preceding months, as measured by Bowen ratio anomalies. Case studies of 2002 (the Rodeo-Chediski and Hayman fires) and 2007 (the Murphy Complex fire) show very high V P D caused by antecedent surface drying and subsidence warming and drying of the atmosphere. V P D has increased in the southwest U.S. since 1961, driven by warming and a drop in actual vapor pressure, but decreased in the northern Plains and midwest, driven by an increase in actual vapor pressure.

title:  Sunflower damage and bird diversity data 2014-2015

description: The “sunflower damage and bird data” provides a summarized dataset on the amount of bird and insect damage to commercial sunflower seed crops in 30 fields in Yolo County, California. Data was collected over 2 years and was spread geographically across the sunflower regions of the county to incorporate fields that were varying distances from remnant natural habitat in the county. Fields had either bare/weedy margins (the linear areas along the edges of fields that are not planted with crops), or had woody vegetation along margins (trellises, riparian corridors, or hedgerows). Sunflower damage was measured by randomly sampling from 10 plants at distances from 0-200m from the field margin and estimating the proportion of all seeds removed by birds or damaged by sunflower head moth. Avian diversity metrics were calculated using data from two site visits in the summer and two in the fall- each visit included a 200m one-sided line transect to count birds utilizing field margin habitat, and a 10- minute point count to count birds utilizing field interiors. Data includes the mean proportion of 10 sampled sunflowers at each distance from the field edge that was damaged by insects or birds. Information on the field margin habitat complexity, the proportion of natural habitat within varying distance bands (50m-800m) from the center of the field margin, and numerous avian diversity and abundance metrics collected in both summer and fall are also included. The exact locations of fields and names of sites are not included to protect farmer privacy. A metadata tab is included in the spreadsheet to provide information about each column of data. Data is presented as an excel file including two tabs- one with the data, and one containing metadata explaining each column.
