    Construction of the sunpath diagrams for Pekan area for simulating the solar radiation effects to a building by Syamimi Soliha, Mohd

    Published 2013
    “…It is because the sun is directly in line with the equator, it is called as the equinox, where the declination angle for equinox is equal to zero. …”

    Uranus in northern midspring: persistent atmospheric temperatures and circulations inferred from thermal imaging by Roman, MT, Fletcher, LN, Orton, GS, Rowe-Gurney, N, Irwin, PGJ

    Published 2020
    “…Using a combination of inverse and forward modeling, we analyze these northern midspring (Ls ~ 46°) images and compare them to archival data to assess seasonal changes since the 1986 southern solstice and subsequent equinox. We find the data are consistent with little change (<0.3 K) in the upper tropospheric temperature structure, extending the previous conclusions of Orton et al. well past equinox, with only a subtle increase in temperature at the emerging north pole. …”

    Longitudinal variations in the stratosphere of Uranus from the Spitzer infrared spectrometer by Rowe-Gurney, N, Fletcher, LN, Orton, GS, Roman, MT, Mainzer, A, Moses, JI, de Pater, I, Irwin, PG

    Published 2021
    “…NASA's Spitzer Infrared Spectrometer (IRS) acquired mid-infrared (5–37 μm) disc-averaged spectra of Uranus very near to its equinox in December 2007. A mean spectrum was constructed from observations of multiple central meridian longitudes, spaced equally around the planet, which has provided the opportunity for the most comprehensive globally-averaged characterisation of Uranus' temperature and composition ever obtained (Orton et al., 2014a,b). …”

    Spatial and seasonal variations in C3Hx hydrocarbon abundance in Titan’s stratosphere from Cassini CIRS observations by Lombardo, NA, Nixon, CA, Achterberg, RK, Jolly, A, Sung, K, Irwin, PGJ, Flasar, FM

    Published 2018
    “…We retrieve vertical abundances profiles between 125 km and 375 km for these gases for latitude averages between 60°S–20°S, 20°S–20°N, and 20°N–60°N over two time periods, 2004 through 2009 representing Titan’s atmosphere before the 2009 equinox, and 2012 through 2015 representing time after the equinox. …”
