Habitat dynamics of flagship species for conservation prioritization in southern Europe. [PDF]
Conserv BiolAbstract Biodiversity loss is accelerating due to human actions, and decision‐making for conservation needs to be streamlined. Ex situ biodiversity modeling and monitoring based on satellite time‐series data could be an affordable and cost‐efficient tool for improving the prioritization of conservation areas.

Space Weather, Volume 21, Issue 9, September 2023., 2023 Abstract This paper investigates the effects of a minor G1 Co‐rotating Interaction Region (CIR)/High‐Speed Stream (HSS)‐driven geomagnetic storm that occurred on (13–14 October 2018), during deep solar minimum. We used simultaneous observations from multiple instruments, namely; ground‐based Global Navigation Satellite Systems (GNSS) receivers, a ...

PPP at Low Latitudes With Ionospheric Model Exclusively Based on Single Frequency GNSS Measurements
Space Weather, Volume 21, Issue 8, August 2023., 2023 Abstract Single frequency users of the Global Navigation Satellite System (GNSS) should correct the ionospheric delay to obtain positioning solutions. A valuable source of ionospheric delay corrections is the global ionospheric models (GIMs) of Vertical Total Electron Content.

Trattato di Geodesia Teoretica [PDF]
Nature, 1905 SIGNOR PIZZETTI has treated the subject of geodesy in a thoroughly exhaustive manner. The theoretical portion of the book, dealing with the formulae used in geodesy, is very ably demonstrated, and the mathematical proofs of the various problems are sufficiently clear to be easily followed by those practically uninitiated in the subject.
