Radiometric Stability Monitoring of the Suomi NPP Visible Infrared Imaging Radiometer Suite (VIIRS) Reflective Solar Bands Using the Moon

Remote Sensing, 2015
The Suomi NPP (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) performs the scheduled lunar roll maneuver on a monthly basis. The lunar calibration coefficients and lunar F-factor are calculated by taking the ratio of the lunar observed radiance

Localization and Classification of Gravity Wave Events From VIIRS Day/Night Band Satellite Imagery Using Machine Learning Techniques

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Gravity waves in the upper mesosphere produce diverse spatial patterns in nighttime airglow, but their global morphology has been difficult to characterize because manual identification is impractical for the massive satellite image archive. We developed a machine learning framework to detect and classify gravity wave events in imagery from ...

Satellite‐Observed Hourly Chlorophyll Variability Associated With Solar Radiation in China's Marginal Seas

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Understanding sub‐daily variability in phytoplankton proxies is essential for interpreting satellite estimates of ocean productivity in marginal seas. Using high‐frequency observations from the Geostationary Ocean Color Imager (GOCI), we assess daytime (08:00–15:00 local time) hourly surface chlorophyll‐a (Chla) variability across China's ...

Mapping the “Supply–Demand–Flow” of Ecosystem Services for Ecosystem Management in China

Advanced Science, Volume 13, Issue 39, 13 July 2026.
This study develops a “supply–demand–flow” framework clarifies how ecosystem services move between regions by distinguishing potential and actual supply and demand. Using integrated biophysical–socioeconomic modeling, nine services in China were mapped.
