Metadata entry - Inferring changes in summertime surface ozone NOx-VOC chemistry over U.S. urban areas from two decades of satellite and ground-based observations

Urban ozone (O3) formation can be limited by NOx, VOCs, or both, complicating the design of effective O3 abatement plans. A satellite-retrieved ratio of formaldehyde to NO2 (HCHO/NO2), developed from theory and modeling, has previously been used to indicate O3 formation chemistry. Here, we connect this space-based indicator to spatiotemporal variations in O3 recorded by on-the-ground monitors over major U.S. cities. High-O3 events vary nonlinearly with OMI HCHO and NO2, and the transition from VOC-limited to NOx-limited O3 formation regimes occurs at higher HCHO/NO2 value (3 to 4) than previously determined from models, with slight intercity variations. To extend satellite records back to 1996, we develop an approach to harmonize observations from GOME and SCIAMACHY that accounts for differences in spatial resolution and overpass time. Two-decade (1996-2016) multisatellite HCHO/NO2 captures the timing and location of the transition from VOC-limited to NOx-limited O3 production regimes in major U.S. cities, which aligns with the observed long-term changes in urban-rural gradient of O3 and the reversal of O3 weekend effect. Our findings suggest promise for applying space-based HCHO/NO2 to interpret local O3 chemistry, particularly with the new-generation satellite instruments that offer finer spatial and temporal resolution.

A multiphase CMAQ version 5.0 adjoint

We present the development of a multiphase adjoint for the Community Multiscale Air Quality (CMAQ) model, a widely used chemical transport model. The adjoint model provides location- and time-specific gradients that can be used in various applications such as backward sensitivity analysis, source attribution, optimal pollution control, data assimilation, and inverse modeling. The science processes of the CMAQ model include gas-phase chemistry, aerosol dynamics and thermodynamics, cloud chemistry and dynamics, diffusion, and advection. Discrete adjoints are implemented for all the science processes, with an additional continuous adjoint for advection. The development of discrete adjoints is assisted with algorithmic differentiation (AD) tools. Particularly, the Kinetic PreProcessor (KPP) is implemented for gas-phase and aqueous chemistry, and two different automatic differentiation tools are used for other processes such as clouds, aerosols, diffusion, and advection. The continuous adjoint of advection is developed manually. For adjoint validation, the brute-force or finite-difference method (FDM) is implemented process by process with box- or column-model simulations. Due to the inherent limitations of the FDM caused by numerical round-off errors, the complex variable method (CVM) is adopted where necessary. The adjoint model often shows better agreement with the CVM than with the FDM. The adjoints of all science processes compare favorably with the FDM and CVM. In an example application of the full multiphase adjoint model, we provide the first estimates of how emissions of particulate matter (PM2.5) affect public health across the US.

Relative contributions of select multigeneration products to chamber SOA formed from photooxidation of a range (C10-C17) of n-alkanes under high NOx conditions

A series of chamber experiments was conducted to investigate the change in the relative contribution of multigeneration reaction products to total secondary organic aerosol (SOA) mass across a range of parent n-alkanes (C10-C17) that has a high potential for SOA formation in urban atmospheres. Contributions of select first, second, and higher generation products to SOA was investigated using online speciation by an aerosol mass spectrometer and varied substantially across the range of investigated alkanes. As expected, the presence of first-generation species in SOA is limited primarily by volatility with small contributions at the low end of the investigated n-alkane range and increasing gradually as the number of carbons is increased. The formation of lower volatility second and higher generation nitrate-containing species, in contrast, appears to be mechanistically limited leading to lower average contributions of organic nitrates to OA as the size of the parent n-alkane is increased. The impact of increased water vapor concentrations similarly varied with the size of the parent alkane with diminished effect as both alkane carbon number and generation number increased. The largest impacts of water, however, were between dry (~3%) and slightly humid (~14%) with little change observed at higher relative humidities.

Maternal High Fat Diet Modify Offspring Susceptibility to Inhaled Ozone-Induced Systemic Metabolic Alterations

Maternal high-fat diet (HFD) and obesity can increase the susceptibility of offspring to inhaled pollutants. In this study, we examined the influence of maternal HFD on metabolic responses to ozone in young Long-Evans rat offspring. F0-females began control (CD; 10%kcal from fat) or high-fat diet (HFD; 60%kcal from fat) at post-natal day (PND)-30. Rats were bred on PND-72 and allowed to give birth. Dietary regimen was maintained until PND-30 and then all offspring were switched to CD. On PND-40, female and male offspring-F1 (n=10/group) were exposed to air or 0.8-ppm ozone for 5h and within 1h serum samples were collected for neuroendocrine hormones and global metabolomic analysis. Offspring from HFD-dams had increased body fat and weight relative to CD, however, no major changes in circulating hormones were noted. Metabolomic analysis revealed significant sex, diet, and exposure-related changes in metabolites. Maternal HFD increased free fatty acids and decreased phospholipids (female>male). Also, microbiome-associated histidine and tyrosine metabolites were increased in both sexes of offspring, while 1,5-anhydroglucitol levels decreased in males. Ozone exposure increased free fatty acids in males from CD-dams but decreased in females from HFD-dams. Ozone also decreased monohydroxy fatty acids and acyl carnitines in females (HFD>CD). Moreover, it increased pyruvate along with TCA cycle intermediates in females suggesting an increase in glucose utilization. Ozone increased various amino acids, polyamines and metabolites of gut microbiota in HFD female offspring. Collectively, these data suggest that maternal HFD increases offspring susceptibility to metabolic alterations in a sex-specific manner when challenged with environmental stressors.

Divergent trends in life expectancy across the rural-urban gradient and association with specific racial proportions in the contiguous United States 2000-2005

We used individual-level death data to estimate county-level life expectancy at 25 (e25) for Whites, Black, AIAN and Asian in the contiguous US for 2000-2005. Race-sex-stratified models were used to examine the associations among e25, rurality and specific race proportion, adjusted for socioeconomic variables. Individual death data from the National Center for Health Statistics were aggregated as death counts into five-year age groups by county and race-sex groups for the contiguous US for years 2000-2005 (National Center for Health Statistics 2000-2005). We used bridged-race population estimates to calculate five-year mortality rates. The bridged population data mapped 31 race categories, as specified in the 1997 Office of Management and Budget standards for the collection of data on race and ethnicity, to the four race categories specified under the 1977 standards (the same as race categories in mortality registration) (Ingram et al. 2003). The urban-rural gradient was represented by the 2003 Rural Urban Continuum Codes (RUCC), which distinguished metropolitan counties by population size, and nonmetropolitan counties by degree of urbanization and adjacency to a metro area (United States Department of Agriculture 2016). We obtained county-level sociodemographic data for 2000-2005 from the US Census Bureau. These included median household income, percent of population attaining greater than high school education (high school%), and percent of county occupied rental units (rent%). We obtained county violent crime from Uniform Crime Reports and used it to calculate mean number of violent crimes per capita (Federal Bureau of Investigation 2010).

E1 E2 metabolism v1

Feminization of male fish and the role of endocrine-active chemicals in this phenomenon has been an area of intense study for many years. Estrone (E1), a natural steroid, is found in aquatic environments sometimes at relatively high concentrations. However, E1 has been less thoroughly studied than 17β-estradiol (E2) or 17α-ethynylestradiol due in part to a relatively lower potency in metabolically-limited estrogen receptor (ER) binding/activation assays. Recent evidence suggests that in vivo biotransformation of E1 to E2 may occur in fathead minnows (Pimephales promelas) residing in environments with high concentrations of E1, such as near wastewater treatment plants. The enzymes likely responsible for this biotransformation, 17β-hydroxysteroid dehydrogenases (17βHSDs), have been well characterized in mammals but to a lesser extent in fish species. In the current study, a novel systematic analysis of amino acid sequence data from the National Center for Biotechnology Information database demonstrated that multiple 17βHSD isoforms are conserved across different fish species. Experimentally, we showed that metabolically-active hepatic cytosolic preparations from two commercially important salmonid species, rainbow trout and lake trout, biotransformed E1 to E2 to a degree sufficient to alter results of competitive ER binding assays. These results from in silico and in vitro analyses indicate E1 and biotransformation may play a significant role in the feminization of a variety of fish species in contaminated aquatic environments.
