This paper presents the project Earth Cooling by Water Vapor Radiation, an observational programme, which aims at developing a database of spectrally resolved far infrared observations, in atmospheric dry conditions, order to validate radiative transfer models and test quality water vapor continuum line parameters. The provides very first set far‐infrared spectral downwelling radiance measurements, are complemented with Raman Lidar‐derived temperature profiles.
We present a new retrieval model designed to analyze the observations of Michelson Interferometer for Passive Atmospheric Sounding (MIPAS), which is on board ENVIronmental SATellite (ENVISAT). The geo-fit multitarget (GMTR) implements two-dimensional inversion simultaneous several targets including set atmospheric constituents that are not considered by ground processor MIPAS experiment. describe innovative solutions adopted in algorithm and main functionalities corresponding computer code....

Measuring water vapor (WV) in the troposphere, where nearly all atmospheric WV is concentrated, critical for understanding composition and dynamics comprehensively. A particularly challenging issue conducting systematic measurements lower troposphere (approximately 5–6 km) on a global scale, as this would significantly enhance both climate modeling numerical weather prediction (NWP) capabilities over short time scales.Based theoretical studies conducted European Space Agency (ESA),...
Pollutants information can be retrieved from visible (VIS) and ultraviolet (UV) diffuse solar spectra exploiting Multi-AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) instruments. In May 2021, the Italian research institute CNR-ISAC acquired deployed a MAX-DOAS system SkySpec-2D. It is located in “Giorgio Fea” observatory San Pietro Capofiume (SPC), middle of Po Valley, where it has constantly zenith off-axis since 1st October 2021. This work presents tropospheric NO2 aerosol...

This study motivated by current understanding streamer nature sprites: streamers are known to produce NO x , thus expected lead a enhancement background abundances, and possibly ozone. We adopted following strategy: middle atmosphere MIPAS/GMTR 2 satellite measurements were correlated with ground‐based WWLLN detections large tropospheric thunderstorms as proxy sprite activity. found no evidence any significant at global...

Abstract. We examine volume mixing ratios (vmr) retrieved from limb emission spectra recorded with the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on board Envisat. In level 2 (L2) data products of three different retrieval processors, which perform one dimensional (1-D) retrievals, we find significant differences between species' profiles ascending and descending orbit parts. The relative vary systematically time year, latitude, altitude. lower stratosphere their...
Recent research on sprites shows these and other transient luminous events can exert a local impact atmospheric chemistry, although with minor effects at global scales. In particular, both modelling remote sensing work suggest perturbations to the background NOx up few tens of per cent occur above active sprite-producing thunderstorms. this study we present detailed investigation MIPAS/ENVISAT satellite measurements middle NO2 in regions high likelihood sprite occurrence during period August...

Observations from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) were analysed with two-dimensional GMTR retrieval system in order to obtain fields of ozone and several molecular species related chemistry: HNO3, N2O, NO2, N2O5, ClONO2, COF2, CFC-11 CFC-12.

<p class="Default">MIPAS is a midinfrared Fourier Transform spectrometer that sounded the atmospheric emission at limb onboard ENVISAT satellite. It was launched on 31 March 2002 in sun-synchronous polar orbit of about 800 km altitude and operated until 8 April 2012. The scanning sequence observed by instrument made spectra sound atmosphere different tangent altitudes (the minimum reached line sight also from where most signal originates). inversion measurements allows determination...

We report the first measurement of isotopic partitioning between stratospheric H 14 NO 3 and 15 . The vertical distribution isotope ratio two isotopologues nitric acid was derived using ν 5 band Q branch that recently identified in measurements from MIPAS experiment newly generated spectral line parameters for minor isotopologue. Because very low intensity features adopted retrieval, we established an “ad hoc” inversion procedure based on a regularized linear Kalman filter approach. This...
