Enhancing Millimeter-Wave Computational Interferometric Imaging
IEEE Access, 2020 Recently a progress in computational imaging has been noticed with the potential to improve the capabilities of millimeter-wave imaging systems. In this paper, an interferometric synthetic aperture systems is considered to be the conventional approach to

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract Snow on sea ice modulates the Earth's radiation budget and sea ice mass balance, yet satellite retrievals of Arctic snow depth remain subject to substantial algorithmic uncertainty. We develop a multi‐model machine learning (ML) framework for retrieving spring snow depth over Arctic sea ice from Advanced Microwave Scanning Radiometer 2 (AMSR2).

, 2001 The measurement of light and colour has always been a peripheral science. Light became a 'disciplined' quantity over the period of a century, but the specialist communities that measured it did not.

Geoscience Data Journal, Volume 13, Issue 3, July 2026.ABSTRACT The Mesosphere and Lower Thermosphere establish an essential connection between Earth's lower atmosphere and upper atmosphere because wind patterns essential for atmospheric movement also influence energy distribution and chemical movements during geomagnetic storms that disrupt satellite operations and space weather prediction systems.

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform
Limnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.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,

Assessment of Trace Element Daily Intake Based on Consumption Rate of Foodstuffs in Bandung City
Atom Indonesia, 2012 Trace elements are required by human body and have a variety role in biochemical functions mostly as catalyst for enzymatic activity in human body. Some trace elements are essential since they are inadequately or not synthesized by human body.

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data
Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Weather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day. Within these “haystacks” of lightning are a handful of “needles” of bolides (aka bright fireballs, or exploding meteors). We have

Statistical Inversion of Sea Surface Temperature to Predict Submesoscale Near‐Surface Ocean Currents
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.Abstract Direct in situ measurements of sea surface currents (SSC) at submesoscales (1–100 km) are challenging. For this reason, inversion techniques have been utilized to infer SSC from satellite sea surface temperature (SST) data, which are straightforward to obtain. However, existing inversion methods often do not adequately account for uncertainty.

Soil Moisture Impact on Convective Initiation
Water Resources Research, Volume 62, Issue 7, July 2026.Abstract The influence of soil moisture on convective storm initiation remains an open question, with previous studies showing conflicting results regarding whether storms preferentially form over wet or dry soils. Here, we analyze the soil moisture‐convection relationship using satellite observations across North America, Africa, and Australia from ...

Training‐Domain Gaps in Data‐Driven Ocean Color Algorithms
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Bio‐optical algorithms serve a critical role, enabling satellite‐based monitoring of the global ocean and its ecosystems. These largely empirical algorithms invert satellite measurements of water leaving reflectance (“ocean color”) to biogeochemical parameters such as chlorophyll a, but often fail to generalize beyond their training data ...
