Geolocation error compensation method for geocoded SAR images using pixel-offset series without control points

International Journal of Digital Earth
SAR spatial geolocation of synthetic aperture radar (SAR) is crucial for SAR/interferometric (In)SAR applications. Geolocation errors often arise owing to factors such as platform instability, instrument degradation, and environmental variations. Current

Development and Initial Validation of the Response to Suicidal Ideation Inventory (RSII)

Journal of Clinical Psychology, EarlyView.
ABSTRACT Objectives Young adults (18–29 years old) often report difficulties coping during suicide crises. However, the responses that young adults employ to manage suicidal ideation (SI) are underexplored. This study developed a new measure to quantify how young adults with a history of suicidal thoughts and behaviors (STBs) respond to their SI, and ...

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

Limnology and Oceanography: Methods, EarlyView.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

Nordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Systemic bio‐inequity links poverty to biodiversity and induces a conservation paradox

People and Nature, EarlyView.
Abstract Biodiversity is declining globally while inequity is growing, and poverty rates are not improving. Global sustainable development and conservation initiatives aim to address biodiversity loss and poverty simultaneously. Through text analysis of global biodiversity policies, we identified a consistent narrative that countries with high ...

The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first

Fine-Grained Arabic Post (Tweet) Geolocation Prediction Using Deep Learning Techniques

Information
Leveraging Twitter data for crisis management necessitates the accurate, fine-grained geolocation of tweets, which unfortunately is often lacking, with only 1–3% of tweets being geolocated.
