COVID-19 measures have necessarily disrupted vaccinations and have been detrimental to measles prevention. As of October 2021, nearly 41 countries had paused their measles campaigns, leaving more than 94 million people at risk of missing vaccines. Therefore, it is critical for public health officials to continue to provide resources, promote vaccination, and change behaviors despite the pandemic. The study’s purpose is to enhance the information-environment level, population-level, and system-level outcomes to determine infectious disease outbreak...

Improving the Analysis and Forecast of Hurricane Dorian (2019) with Simultaneous Assimilation of GOES-16 All-Sky Infrared Brightness Temperatures and Tail Doppler Radar Radial Velocities

C.M. Hartman, X. Chen, E.E. Clothiaux & M. Chan
Recent studies have shown that the assimilation of all-sky infrared (IR) observations can be beneficial for tropical cyclone analyses and predictions. The assimilation of tail Doppler radar (TDR) radial velocity observations has also been shown to improve tropical cyclone analyses and predictions; however, there is a paucity of literature on the impacts of simultaneously assimilating them with all-sky IR brightness temperatures (BTs). This study examines the impacts of assimilating combinations of GOES-16 all-sky IR brightness...

Idealized atmospheric boundary layer and tornado simulations for Wang et al. (2022) two-layer-model study.

A. Wang, Y. Pan, G. Bryan & P. Markowski
This dataset contains the numerical simulations used in the Wang et al. (2022) study of two-layer-model in an idealized atmospheric boundary layer and an idealized tornado. That work modifies a wall model from the engineering community known as two-layer model (TLM) to a widely used atmospheric LES mode, Cloud Model 1 (CM1). LES of an idealized, neutral atmospheric boundary layer are performed first, in order to validate the implementation of the TLM in CM1. Next,...

Model Input, Analysis Code, and Select Model Output for the Murdzek et al. (2022) Ordinary Convection Sensitivity Study

S. Murdzek, P. Markowski, Y.P. Richardson & M.R. Kumjian
This dataset contains all relevant Cloud Model 1 (CM1) input files, python analysis code, and select CM1 output for the Murdzek et al. (2022, MWR) study that explores how the sensitivity of simulated ordinary convection changes in environments with different lifting condensation levels (LCLs). Enough CM1 output is provided to recreate most of the figures from Murdzek et al. (2022), and the rest of the output can be recreated using the supplied input files.

Data for Coco et al. 2022 Oecologia, More phylogenetically diverse polycultures inconsistently suppress insect herbivore populations

A.M. Coco, E.C. Yip, I. Kaplan & J.F. Tooker
Because the diet of many herbivorous insects is restricted to closely related taxa with similar chemistry, intercropping with diverse plant communities may reduce both pest populations and reliance on chemical pesticides in agroecosystems. We tested whether the effectiveness of intercropping against herbivorous insects depends on the phylogenetic relatedness of neighboring crops, using butternut squash (Cucurbita moschata) as a focal crop species in a series of different intercropping combinations. We found that increased phylogenetic divergence of...

Assessing a century of maize and soybean polyculture for silage production: Data

A.B. Burton & A.R. Kemanian
This dataset and accompanying supplemental materials are companion pieces to the journal article “Assessing a century of maize and soybean polyculture for silage production” published in Agronomy Journal in 2022 by Burton & Kemanian. Maize (Zea mays L.) silage is an important source of feed for ruminant animals. However, maize monocultures are exposed to both abiotic and biotic stresses that can reduce yield and contribute to environmental degradation. Over the past century, maize + soy...

Prodigious amounts of hydrogen oxides generated by corona discharges on tree leaves

J.M. Jenkins, G.A. Olson, P.J. McFarland & W.H. Brune
Prodigious amounts of the hydroxyl radical (OH) are generated by weak electrical discharges, such as corona discharges induced on trees during thunderstorms. As was observed in studies of sparks and subvisible discharges, corona discharges on leaves produce OH and hydroperoxyl (HO2) amounts that are several orders of magnitude larger than usual. Our laboratory studies demonstrate that production rates of OH and HO2 depend on the applied electric field that generates the corona discharge, leaf dryness,...

Seesaw production and pollution associated with COVID-19-like supply chain disruptions in an agroecosystem model, Cycles Data

R. Rozum
Sudden global disruptions in agricultural commodities demand or input supply have local immediate effects on the economy and the environment. Recognizing these patterns can help society and agricultural stakeholders prepare and react to these disruptions. This research addresses the use of agricultural decision support systems (DSS) to quickly assess the impacts of disruptions like the COVID-19 pandemic on agroecosystem production output and pollution. We diagnosed the effect of assumed labor and agrochemical supply disruptions on...

Coarse-Grained Models for Local Density Gradients

M.R. DeLyser & W.G. Noid
Coarse-grained (CG) models provide superior computational efficiency for simulating soft materials. Unfortunately, CG models with conventional pair-additive potentials demonstrate limited transferability between bulk and interfacial environments. Recently, a growing number of CG models have supplemented these pair potentials with one-body potentials of the local density (LD) around each site. These LD potentials can significantly improve the accuracy and transferability of CG models. Nevertheless, it remains challenging to accurately describe interfaces where the LD varies rapidly....

Electrodynamic Levitation Diffusion Chamber Measurements of the Mass Growth of Ice Crystals Grown from the Vapor at -65 to -40C

G. Pokrifka, A. Myle & J.Y. Harrington
This data set comprises individual time-series for ice crystals grown in an electrodynamic levitation diffusion chamber at temperatures between -65 and -40C. Descriptions of the chamber and experimental proceedure can be found in Harrison et al. (2016), Pokrifka et al. (2020), and Pokrifka et al. (submitted to J. Atmos. Sci. 2022). Experiments were conducted by freezing small (approximately 10 micrometer radius) droplets either homogeneously or heterogeneously with a 0.2 g/L Snomax mixture. Frozen droplets were...

Supplementary data, code, and information for ‘Interhemispheric antiphasing of neotropical precipitation during the past millennium’ (PNAS, Steinman et al. 2022)

B.A. Steinman, N. Stansall, M.E. Mann, C.A. Cooke, M.B. Abbott, M. Vuille, B.W. Bird, M.S. Lachniet & A. Fernandez
Uncertainty about the influence of anthropogenic radiative forcing on the position and strength of convective rainfall in the Intertropical Convergence Zone (ITCZ) inhibits our ability to project future tropical hydroclimate change in a warmer world. Paleoclimatic and modeling data inform on the timescales and mechanisms of ITCZ variability; yet a comprehensive, long-term perspective remains elusive. Here, we quantify the evolution of neotropical hydroclimate over the pre-industrial past millennium (850 to 1850 CE) using a synthesis...

Strategies to Mitigate Enteric Methane Emissions by Ruminants

C. Arndt, A.N. Hristov, W.J. Price, S.C. McClelland, A.M. Pelaez, A.R. Bayat, L.A. Crompton, J. Dijkstra, M.A. Eugène, D. Enahoro, E. Kebreab, M. Kreuzer, M. McGee, C. Martin, C.J. Newbold, C.K. Reynolds, A. Schwarm, K.J. Shingfield, J.B. Veneman, D.R. Yáñez-Ruiz & Z. Yu
To meet the 1.5°C target, methane (CH4) from ruminants must be reduced by 11 to 30% of the 2010 level by 2030 and by 24 to 47% by 2050. A meta-analysis identified strategies to decrease product-based [PB; CH4 per unit meat or milk (CH4I)] and absolute (ABS) enteric CH4 emissions while maintaining or increasing animal productivity (AP; weight gain and milk yield). Next the potential of different adoption rates of one PB and/or ABS strategies...

Extreme hydroxyl amounts generated by thunderstorm-induced corona on grounded metal objects

W.H. Brune, J.M. Jenkins, G.A. Olson, P.J. McFarland, D.O. Miller, J. Mao & X. Ren
It has now been established that atmospheric electrical discharges generate unexpectedly large amounts of the atmosphere’s primary oxidant, hydroxyl (OH) in thunderstorm anvils, where lightning and weak electrical discharges are caused by atmospheric charge separation. The question is “Do other atmospheric electrical discharges also generate large amounts of oxidants?’ In this paper, we demonstrate that coronas formed on grounded metal objects produce extreme amounts of hydroxyl (OH), hydroperoxyl (HO2), and ozone (O3) when thunderstorms are...
