Assessment of Observed and Projected Extreme Droughts in Perú—Case Study: Candarave, Tacna by Ana Cruz-Baltuano, Raúl Huarahuara-Toma, Arlette Silva-Borda, Samuel Chucuya, Pablo Franco-León, Germán Huayna, Lía Ramos-Fernández, Edwin Pino-Vargas

“…Additionally, it was concluded that the VCI also detected the droughts identified by the SPEI; however, a more detailed analysis of its use is necessary due to the limited availability of suitable satellite images in the area. On the other hand, a high-resolution dataset of climate models from the sixth phase of the Coupled Model Intercomparison Project (CMIP6) under the SSP3-7.0 scenario was used to project future droughts. …”

Greening of Svalbard in the twentieth century driven by sea ice loss and glaciers retreat by Gianmarco Ingrosso, Chiara Ceccarelli, Federico Giglio, Patrizia Giordano, Jens Hefter, Leonardo Langone, Stefano Miserocchi, Gesine Mollenhauer, Alessio Nogarotto, Mathia Sabino, Tommaso Tesi

“…Abstract The greening of previously barren landscapes in the Arctic is one of the most relevant responses of terrestrial ecosystem to climate change. Analyses of satellite data (available since ~1980) have revealed a widespread tundra advance consistent with recent global warming, but the length is insufficient to resolve the long-term variability and the precise timing of the greening onset. …”

Variability of Ionosphere Over Indian Longitudes to a Variety of Space Weather Events During December 2006 by Alok Kuman Ranjan, M. V. Sunil Krishna, C. Amory‐Mazaudier, R. Fleury, S. Sripathi, Geeta Vichare, W. Younas

“…The variability of the ionosphere over the Indian longitude sector due to these intense space weather fluctuations is presented by utilizing the magnetometers, ionosonde, GPS vTEC, and satellite‐based observations in the same region. This study reports the influence of prompt penetration of the magnetospheric convection electric field and the disturbance dynamo on several key ionospheric and magnetic parameters within the Indian longitude sector.…”

Weak magnetism of Martian impact basins may reflect cooling in a reversing dynamo by S. C. Steele, R. R. Fu, A. Mittelholz, A. I. Ermakov, R. I. Citron, R. J. Lillis

“…Abstract Understanding the longevity of Mars’s dynamo is key to interpreting the planet’s atmospheric loss history and the properties of its deep interior. Satellite data showing magnetic lows above many large impact basins formed 4.1-3.7 billion years ago (Ga) have been interpreted as evidence that Mars’s dynamo terminated before 4.1 Ga—at least 0.4 Gy before intense late Noachian/early Hesperian hydrological activity. …”
