Transport into the polar stratosphere from the Asian monsoon region by X. Yan, P. Konopka, F. Ploeger, F. Ploeger, A. Podglajen

“…We use SF<span class="inline-formula">₆</span> observations and the Lagrangian chemistry transport model Chemical Lagrangian Model of the Stratosphere (CLaMS), driven by the ERA5 reanalysis data for the period 2010–2014, to assess the impact of the Asian monsoon (AM) region (15–45° N, 30–120° E) as a significant source of pollutants for the stratosphere, in particular in polar regions. We examine the contribution of transport from the AM region to the Northern Hemisphere polar region (NP) (60–90° N) and to the Southern Hemisphere polar region (SP) (60–90° S). …”

Reply to Comment by A. G. Davies on “Io Hot Spot Distribution Detected by Juno/JIRAM” by F. Zambon, A. Mura, F. Tosi

“…They identified 242 hot spots, including 23 not previously reported in other catalogs, observing a higher hot spot number density in the northern polar region. Davies (2024) disputes location and counting of part of these hot spots, attributing the differences between the Zambon et al. (2023, https://doi.org/10.1029/2022gl100597) results and those obtained by Davies et al. (2024, https://doi.org/10.1038/s41550‐023‐02123‐5) to a misregistration of the JIRAM images. …”

Impact of Annually Variable Dust Activity on the Recession of the Martian South Polar Seasonal Cap by Zhibin Li, Jianjun Liu, Renhao Tian, Zhaopeng Chen, Qing Zhang, Jingjing Zhang, Wei Yan, Qiang Fu, Shaoran Liu, Nannan Ma

“…Continuous observations of SPSC/South Polar Residual Cap (SPRC) across several Martian years, alongside segmented analyses of annual dust activity, will provide new insights into the climate conditions of Martian south polar region. Here, we performed a combined analysis on the extents of SPSC from MY28-MY31 and MY36, together with the concurrent Martian atmospheric optical thickness, to assess the influence of dust activity at various recession time steps. …”

The Deuterium Isotopic Ratio of Water Released From the Martian Caps as Measured With TGO/NOMAD by Geronimo L. Villanueva, Giuliano Liuzzi, Shohei Aoki, Shane W. Stone, Adrian Brines, Ian R. Thomas, Miguel Angel Lopez‐Valverde, Loic Trompet, Justin Erwin, Frank Daerden, Bojan Ristic, Michael D. Smith, Michael J. Mumma, Sara Faggi, Vincent Kofman, Séverine Robert, Lori Neary, Manish Patel, Giancarlo Bellucci, Jose Juan Lopez‐Moreno, Ann Carine Vandaele

“…We investigated the release of seasonal water from the polar caps during southern and northern summer, by mapping water and its D/H near the polar regions. Above the hygropause, the D/H drops substantially below 2 VSMOW, and both seasonal polar caps show a consistent and enriched D/H of 5–7 VSMOW within the hygrosphere.…”

Latitudinal Dependence of Cosmic Rays Modulation at 1 AU and Interplanetary Magnetic Field Polar Correction by P. Bobik, G. Boella, M. J. Boschini, C. Consolandi, S. Della Torre, M. Gervasi, D. Grandi, K. Kudela, S. Pensotti, P. G. Rancoita, D. Rozza, M. Tacconi

“…This treatment of the IMF, implemented in the HelMod Monte Carlo code (version 2.0), was used to determine the effects on the differential intensity of Proton at 1 AU and allowed one to investigate how latitudinal gradients of proton intensities, observed in the inner heliosphere with the Ulysses spacecraft during 1995, can be affected by the modification of the IMF in the polar regions.…”

Analyzing the observational capabilities of a Moon-based platform for monitoring Earth’s outgoing radiation by Guang Liu, Runbo Dong, Yin Jin, Mengxiong Zhou, Hanlin Ye, Rui Song, Jan-Peter Muller, Huadong Guo

“…The results show that: 1) the lowest daily ground coverage rate is about 88.8% and global coverage including polar regions can always be achieved within a month; 2) the sampling interval needs to be less than 4 hours to ensure the accuracy of reconstruction; 3) the image captured by a multi-spectral camera is capable of reconstructing the distribution of the Earth’s outgoing radiation, while the data obtained from a radiometer facilitates the reconstruction of the global Earth’s outgoing radiation, thereby enabling a comprehensive assessment of the Earth’s outgoing radiation. …”

Effects of Level of Retrieval Success on Recall-Related Frontal and Medial Temporal Lobe Activations by Daniela Montaldi, Andrew R. Mayes, Anna Barnes, Donald M. Hadley, Jim Patterson, David J. Wyper

“…The frontal activations occurred mainly in the dorsolateral region, but extended into the ventrolateral and, to a lesser extent, the frontal polar regions. It is argued that whereas the medial temporal lobe activation increased as the proportion of response words successfully recalled increased, the bilateral frontal lobe activation increased in proportion to retrieval effort, which was greater when learning had been less good.…”
