Uncertainty assessment for a novel optically shallow water radiometric acquisition platform
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,

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data
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
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
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
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 ...

Assessment of Trace Element Daily Intake Based on Consumption Rate of Foodstuffs in Bandung City
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.

Abstract Strong Thermal Emission Velocity Enhancement (STEVE) is a nightsky optical phenomenon of great research interest in recent years. STEVE is recognized to be co‐located with a latitudinally narrow channel of fast westward ion drifts, also known as “subauroral ion drifts” (SAID).

Gravity Wave Activity in the Stratosphere and Mesosphere During Hurricane Sam
Abstract Multi‐instrument observations of gravity wave (GW) activity during Hurricane Sam (2021) were made using AIRS (Atmospheric Infrared Sounder) satellite data, ERA5 reanalysis, and TIMED/SABER temperature profiles. Two GW extraction methods, vertical high‐pass filtering and empirical mode decomposition, were applied to quantify wave‐induced ...

WACCM‐RR: A Regionally‐Refined Version of the Whole Atmosphere Community Climate Model
Abstract We introduce the Whole Atmosphere Community Climate Model with Regional Refinement (WACCM‐RR) and study the impact of directly resolving gravity waves (GWs) in the mesosphere and lower thermosphere (MLT; 70–140 km). Two simulations of 2010 are compared: “Non‐RR” is a standard WACCM case with a horizontal resolution of ∼1° (111 km) globally ...
