Abstract NRLMSIS® 2.0 is an empirical atmospheric model that extends from the ground to exobase and describes average observed behavior of temperature, eight species densities, mass density via a parametric analytic formulation. The inputs are location, day year, time day, solar activity, geomagnetic activity. NRLMSIS major, reformulated upgrade previous version, NRLMSISE‐00. now couples thermospheric densities entire column, effective profile transitions each fully mixed region below ~70 km...

Retrieval of abundances atmospheric species from limb infrared emission spectra requires accurate knowledge the pointing instrument in terms elevation, as well temperature and pressure profiles. An optimal estimation‐based method is presented to infer these quantities measured spectra. The successful efficient joint retrieval largely correlated depends strongly on proper selection space, spectral microwindows, choice reasonable constraints which force solution be stable. proposed strategy...

Abstract. The MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) instrument has been operating on-board the ENVISAT satellite since March 2002. In first two years, it acquired in a nearly continuous manner high resolution (0.025 cm−1 unapodized) emission spectra of Earth's atmosphere at limb middle infrared region. This paper describes level 2 near real-time (NRT) and off-line (OL) ESA processors that have used to derive geophysical products from calibrated geolocated 1b...
Pronounced upper stratospheric and mesospheric NO x enhancements were measured by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) in Southern Hemisphere (SH) polar vortex from May to August 2003, reaching average abundances of 60 ppbv at 50–60 km July. Peak mixing ratios around 200 night, representing highest values ever recorded SH. The observed are attributed production electron precipitation mesosphere lower thermosphere subsequent descent with meridional...
Abstract. Solar eruptions sometimes produce protons, which impact the Earth's atmosphere. These solar proton events (SPEs) generally last a few days and high energy particles that precipitate into The protons cause ionization dissociation processes ultimately lead to an enhancement of odd-hydrogen odd-nitrogen in polar cap regions (>60° geomagnetic latitude). We have used Whole Atmosphere Community Climate Model (WACCM3) study atmospheric SPEs over period 1963–2005. very largest were...

In this paper, we analyze the strong unidentified emission near 3.28 μm in Titan's upper daytime atmosphere recently discovered by Dinelli et al. We have studied it using NASA Ames PAH IR Spectroscopic Database. The polycyclic aromatic hydrocarbons (PAHs), after absorbing UV solar radiation, are able to emit strongly 3.3 μm. By current models for redistribution of absorbed energy, explained observed spectral feature and derived vertical distribution abundances atmosphere. PAHs been found be...
Evaluating the representation of processes controlling tropical and subtropical tropospheric relative humidity (RH) in atmospheric general circulation models (GCMs) is crucial to assess credibility predicted climate changes. GCMs have long exhibited a moist bias mid upper troposphere, which could be due mis‐representation cloud or large‐scale circulation, excessive diffusion during water vapor transport. The goal this study use observations isotopic ratio understand cause bias. We compare...
