Deriving All‐Hour Aerosol Optical Depth Over China From Automated Visibility Observations
Abstract All‐hour aerosol monitoring remains challenging due to limited spatiotemporal coverage of current observational systems. Here we developed a machine‐learning based framework that derives 24‐hr aerosol optical depth (AOD) from automated visibility measurements.

Retrieval and Attribution of Tropical Cyclone Vertical Tilt From SAR and Infrared Satellite Imagery
Abstract Tropical cyclones (TCs) are destructive natural hazards, and their vertical tilt, defined as the displacement between the sea surface center and cloud top center, plays a key role in storm structure and intensity changes. This study constructed a global satellite‐based tilt data set from 1,024 paired synthetic aperture radar (SAR) and infrared

CNN‐Based Retrieval of 3D Cloud Structures Solely From Geostationary Satellite Imagery
Abstract The cloud vertical structure (CVS) is important, yet operational CVS products depend on active observation or reanalysis fields, limiting high‐frequency monitoring. In this study, we propose a lightweight and satellite‐only model that reconstructs volumetric cloud masks from geostationary multispectral imagery.

Generating himawari-8 time series data for meteorological application
Optical remote sensing images have been widely used for temporal monitoring. The data is acquired by sensors on satellites with better spatial resolution compared to in-situ measurements by meteorological stations. The problem with utilizing optical images is the cloud, which blocks the ground and near-ground information collected by satellites.

Abstract Cherenkov detectors have been used in space for decades to measure Galactic Cosmic Rays (GCRs), Solar Energetic Particles (SEPs) and trapped particles. We present proof‐of‐concept GRAS/Geant4 simulations to both show that a cubic fused silica Cherenkov detector with SiPM in LEO has a good sensitivity to SEP and GCR protons as a function of cut‐

New interpretable deep learning model to monitor real-time PM2.5 concentrations from satellite data
Particulate matter with a mass concentration of particles with a diameter less than 2.5 μm (PM2.5) is a key air quality parameter. A real-time knowledge of PM2.5 is highly valuable for lowering the risk of detrimental impacts on human health.

The biological response triggered by a tropical cyclone (TC) passage has attracted much attention due to its possible impacts on regional oceanic, ecological environment, and regional climate balance. However, the detailed progress of TC-induced chlorophyll-a (Chl-a) responses (TICRs) remains unclear due to the inherent limitation of observations in ...

Abstract This study presents simultaneous measurements of electron phase space density (PSD) gradients in geostationary orbit using data from GK2A, GOES‐16, and GOES‐17. By leveraging a three‐satellite configuration, we provide statistical results of PSD gradient estimation in invariant coordinates.
