Abstract Tropospheric ozone plays a major role in Earth’s atmospheric chemistry processes and also acts as an air pollutant greenhouse gas. Due to its short lifetime, dependence on sunlight precursor emissions from natural anthropogenic sources, tropospheric ozone’s abundance is highly variable space time seasonal, interannual decadal time-scales. Recent, sometimes rapid, changes observed mixing ratios inspired us produce this up-to-date overview of global distribution trends. Much the text...
We define the radiative forcings used in climate simulations with SI2000 version of Goddard Institute for Space Studies (GISS) global model. These include temporal variations well‐mixed greenhouse gases, stratospheric aerosols, solar irradiance, ozone, water vapor, and tropospheric aerosols. Our illustrations focus on period 1951–2050, but we make full data sets available those which have earlier data. illustrate response to these model specified sea surface temperature a simple Q ‐flux...
Planets, embedded in their natal discs, harbour hot envelopes. When pebbles are accreted by these planets, the contained volatile components may sublimate, enriching envelope and potentially changing its thermodynamical properties. However, envelopes of planets actively exchange material with disc, which would limit buildup a vapour-rich atmosphere. To properly investigate processes, we have developed new phase change module to treat sublimation process hydrodynamical simultions. Combined...
Context. Protoplanetary disks, the birthplaces of planets, commonly feature bright rings and dark gaps in both continuum line emission maps. Accreting planets interact with disk, not only through gravity, but also by changing local irradiation elemental abundances, which are essential ingredients for disk chemistry. Aims. We propose that giant planet accretion can leave chemical footprints gas to planet, potentially leads spatial coincidence molecular emissions ALMA observations. Methods....

New results are reported from a measurement of $\pi^0$ electroproduction near threshold using the $p(e,e^{\prime} p)\pi^0$ reaction. The experiment was designed to determine precisely energy dependence $s-$ and $p-$wave electromagnetic multipoles as stringent test predictions Chiral Perturbation Theory (ChPT). data were taken with an electron beam 1192 MeV two-spectrometer setup in Hall A at Jefferson Lab. For first time, complete coverage $\phi^*_{\pi}$ $\theta^*_{\pi}$ angles $p \pi^0$...
Abstract. Trace gas measurements of TOPSE and TRACE-P experiments corresponding global GEOS-CHEM model simulations are analyzed with the Positive Matrix Factorization (PMF) method for evaluation purposes. Specially, we evaluate simulated contributions to O3 variability from stratospheric transport, intercontinental production urban/industry biomass burning/biogenic sources. We select a suite relatively long-lived tracers, including 7 chemicals (O3, NOy, PAN, CO, C3H8, CH3Cl, 7Be) 1 dynamic...
