Material Property Database of Organic Liquids, Ices, and Hazes on Titan
<p>Titan has a diverse range of materials in its atmosphere and on its surface: the simple organics that reside in various phases (gas, liquid, ice) and the solid complex refractory organics that form Titan's haze layers. These materials all actively participate in various physical processes on Titan, and many material properties are found to be important in shaping these processes. Future in-situ exploration on Titan would likely encounter a range of materials, and a comprehensive database to archive the material properties of all possible material candidates will be needed.</p> <p>Here we archive several important material properties of the organic liquids, ices, and the refractory hazes on Titan that are available in the literature and/or that we have computed. These properties include thermodynamic properties (phase change points, sublimation and vaporization saturation vapor pressure, and latent heat), physical property (density), and surface properties (liquid surface tensions and solid surface energies).</p> <p>We have archived all the data involved in our first paper (https://arxiv.org/abs/2210.01394 for the Arxiv version and https://doi.org/10.3847/1538-4365/acc6cf for the publisher version) here to make them available to the science community. These data can be used as inputs for various theoretical models to interpret current and future remote sensing and in-situ atmospheric and surface measurements on Titan. The material properties of the simple organics may also be applicable to giant planets and icy bodies in the outer solar system, interstellar medium, and protoplanetary disks.</p> <p>The "Summary of Data Tables and Jupyter Notebook Files" summarizes the names of all the data files (.csv) and Jupyter Notebook files (.ipynb) and their corresponding Tables in the paper.</p> <p><strong>Please cite our paper in your use of the data: Yu et al.

3D simulations of TRAPPIST-1e with varying CO2, CH4 and haze profiles [dataset]
<p>Dataset of 3D simulations of TRAPPIST-1e with varying CO2, CH4 and haze profiles</p><p> </p><p>Using a 3D General Circulation Model, the Unified Model, we present results from simulations of a tidally locked TRAPPIST-1e with varying CO2 and CH4 gas concentrations, and their corresponding prescribed spherical haze profiles. Our results show that the presence of CO2 leads to a warmer atmosphere globally due to its greenhouse effect, with the increase of surface temperature on the day side surface up to ∼14.1 K, and on the night side up to ∼21.2 K. The presence of CH4 can lead to a peak in the change of surface temperature on the day side due to the balance of tropospheric warming and stratospheric cooling. A thin layer of haze, formed when CH4/CO2 = 0.1, leads to a day side warming of ∼4.9 K due to a change in the water vapour and cloud distribution. The haze reaches an optical threshold thickness when CH4/CO2 ∼0.4 beyond which the day side mean surface temperature does not vary much. The planet is more favourable to habitability (surface temperature above 273.15 K) when pCO2 is high, pCH4 is low and the haze layer is thin. The effect of CO2, CH4 and haze on the day side is similar to that for a rapidly-rotating planet. On the contrary, their effect on the night side depends on the wind structure and the wind speed in the simulation.</p>

Important contribution of N2O5 hydrolysis to the daytime nitrate in Xi'an, China during haze periods: isotopic analysis and WRF-Chem model simulation
<p>To quantify the contributions of major formation pathways to nitrate, a field observation, coupling with a WRF-Chem model simulation, was conducted in Xi’an, an inland megacity of China. Here is the dataset of ions, stable isotope compositions of nitrogen and oxygen of nitrate, T, RH and the results simulated by WRF-Chem model.</p>
Enhanced oxidation of SO2 by H2O2 during haze events: constraints from sulfur isotopes
<p>Sulfate aerosols play a critical role in atmospheric chemistry and climate change. However, the mechanism of sulfate formation during haze events remains highly uncertain. In this work, sulfur isotopic compositions of SO<sub>2</sub> and sulfate in PM<sub>2.5</sub> samples collected in Tianjin, China as well as a Rayleigh distillation model are used to constrain SO<sub>2</sub> oxidation pathways. Here, we show the sulfur isotopic compositions of SO<sub>2</sub> and sulfate as well as concentrations of major ions in PM2.5. Our results show that a large sulfur isotope fractionation between SO<sub>2</sub> and sulfate observed in the first stage of haze events may be attributed to an enhanced oxidation of SO<sub>2</sub> by H<sub>2</sub>O<sub>2</sub>. This study highlights the important role of SO<sub>2</sub> oxidation by H<sub>2</sub>O<sub>2</sub> during the haze events. In addition, it is particularly important to note that the sulfur isotopic fractionation factors during haze events dispaly a distinct trend to other periods, indicating that this isotopic approach is useful in understanding the sulfate formation during haze events.</p>
3D simulations of the Archean Earth including photochemical haze profiles [dataset]
<p>Dataset of 3D simulations of the Archean Earth including photochemical haze profiles</p> <p>We present results from 3D simulations of the Archean Earth including a prescribed spherical haze generated through a 1D photochemical model. Our simulations suggest that a thin haze layer, formed when CH4/CO2 = 0.1, leads to global warming of ~10.6K due to the change of water vapour and cloud feedback, compared to the simulation without any haze. However, a thicker haze layer, formed when CH4/CO2 > 0.1, leads to global cooling of up to ~65K as the scattering and absorption of shortwave radiation from the haze reduces the radiation from reaching the planetary surface. A thermal inversion is formed with a lower tropopause as the CH4/CO2 ratio increases. The haze reaches an optical threshold thickness when CH4/CO2 ~ 0.175 beyond which the atmospheric structure and the global surface temperature do not vary much.</p> <p> </p> <p>The IRIS python package developed by the Met Office is needed to analyse the data.</p>
