Seasonal changes in Titan's polar trace gas abundance observed by cassini by Teanby, N, Irwin, P, De Kok, R, Nixon, C

“…During most of Cassini's mission Titan's northern hemisphere has been in winter, with an intense stratospheric polar vortex highly enriched in trace gases, and a single south-to-north circulation cell. …”

Characteristics of Titan's stratospheric aerosols and condensate clouds from Cassini CIRS far-infrared spectra by de Kok, R, Irwin, P, Teanby, N, Nixon, C, Jennings, D, Fletcher, L, Howett, C, Calcutt, S, Bowles, N, Flasar, F, Taylor, F

“…Haze B is much more abundant in the northern hemisphere compared to the southern hemisphere. …”

Saturn’s tropospheric particles phase function and spatial distribution from Cassini ISS 2010–11 observations by Pérez-Hoyos, S, Sanz-Requena, J, Sánchez-Lavega, A, Irwin, P, Smith, A

“…Results for the particle phase function are also used to describe the spatial distribution of tropospheric particles both vertically and latitudinally in the Northern hemisphere.…”

Saturn's tropospheric particles phase function and spatial distribution from Cassini ISS 2010-11 observations by Pérez-Hoyos, S, Sanz-Requena, J, Sánchez-Lavega, A, Irwin, P, Smith, A

“…Results for the particle phase function are also used to describe the spatial distribution of tropospheric particles both vertically and latitudinally in the Northern hemisphere.…”

Constraints on Uranus's haze structure, formation and transport by Toledo, D, Irwin, P, Rannou, P, Teanby, N, Simon, A, Wong, M, Orton, G

“…However, these timescales are too big to explain the observed variations in the haze structure over Uranus's northern hemisphere after 2007 equinox (e.g. de Pater et al., 2015). …”

Observations of upper tropospheric acetylene on Saturn: No apparent correlation with 2000 km-sized thunderstorms by Hurley, J, Irwin, P, Fletcher, L, Moses, J, Hesman, B, Sinclair, J, Merlet, C

“…It is likely that the magnitude of the enhancement theorised is too generous or that enhancements are not advected into the upper troposphere as vertical mixing rates in models would suggest, since Cassini/CIRS can only detect C 2H 2 above the 200 mbar level - although the massive northern hemisphere thunderstorm of 2010/2011 seems able to decrease stratospheric concentrations of C 2H 2. …”

Seasonal variations of temperature, acetylene and ethane in Saturn's atmosphere from 2005 to 2010, as observed by Cassini-CIRS by Sinclair, J, Irwin, P, Fletcher, L, Moses, J, Greathouse, T, Friedson, A, Hesman, B, Hurley, J, Merlet, C

“…Ethane exhibits a general enrichment at mid-northern latitudes from 2005 to 2009. As the northern hemisphere approaches summer solstice in 2017, this feature might indicate an onset of a meridional enrichment of ethane, as has been observed in the southern hemisphere during/after southern summer solstice. © 2013 Elsevier Inc.…”

Climatology and first-order composition estimates of mesospheric clouds from Mars Climate Sounder limb spectra by Sefton-Nash, E, Teanby, N, Montabone, L, Irwin, P, Hurley, J, Calcutt, S

“…They form in equatorial regions (30°S-30°N) during the aphelion season/northern hemisphere summer (Ls<150°), which is in agreement with previous published observations of mesospheric clouds. …”

Characterising Saturn's vertical temperature structure from Cassini/CIRS by Fletcher, L, Irwin, P, Teanby, N, Orton, G, Parrish, P, de Kok, R, Howett, C, Calcutt, S, Bowles, N, Taylor, F

“…The para-hydrogen fraction in the 100-400 mbar range is greater than equilibrium predictions for the southern hemisphere and parts of the northern hemisphere, and less than equilibrium predictions polewards of 40° N. …”

Hunting for water with MCS by Lolachi, R

“…In the final part, a two-stage retrieval method was applied to MCS observations for MY28 northern hemisphere summer (Ls=111–173°). Nightside vertical profiles of water vapour were retrieved for the first time showing interaction with the aphelion cloud belt directly. …”

Mid-infrared mapping of Jupiter’s temperatures, aerosol opacity and chemical distributions with IRTF/TEXES by Fletcher, L, Greathouse, T, Orton, G, Sinclair, J, Giles, R, Irwin, P, Encrenaz, T

“…Jupiter's stratosphere is notably warmer at northern mid-latitudes than in the south in both 2000 and 2014, although the latter can be largely attributed to strong thermal wave activity near 30°N that dominates the 2014 stratospheric maps and may be responsible for elevated C2H2 in the northern hemisphere. A vertically-variable pattern of temperature and windshear minima and maxima associated with Jupiter's Quasi Quadrennial Oscillation (QQO) is observed at the equator in both datasets, although the contrasts were more subdued in 2014. …”

Evidence for anomalous cloud particles at the poles of Venus by Wilson, C, Guerlet, S, Irwin, P, Tsang, C, Taylor, F, Carlson, R, Drossart, P, Piccioni, G

“…We find no persistent latitudinal variation in cloud properties a low to midlatitudes, nor do we find asymmetry between the southern and northern hemispheres. These findings arise from analysis of the relative brightness of 1.74 and 2.30 [mu]m infrared radiation thermally emitted from the deep atmosphere of Venus. …”
