OCO‐3 Meets ECOSTRESS: Insights Into Ecosystem Diurnal Water‐Use Efficiency From Co‐Located Solar‐Induced Fluorescence and Thermal Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Terrestrial ecosystem regulation of carbon and water fluxes is critical for constraining climate–biosphere feedbacks but remains poorly quantified across space and time. Here, we evaluate whether co‐located observations from NASA's Orbiting Carbon Observatory‐3 (OCO‐3) and the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station

Lightning Source of Nitrogen Oxides (NOx) Inferred From Geostationary Satellites: Global Implications for Oxidant Chemistry

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Lightning is a major source of nitrogen oxide radicals (NOx ≡ NO + NO2), but large uncertainties in NOx yields per flash hinder accurate quantification of emissions and impacts on oxidant chemistry. We use 1 year of concurrent geostationary satellite observations of free tropospheric (FT) NO2 from TEMPO and flash rates from GLM to show that ...

Technical Note: Evolution, current capabilities, and future advance in satellite nadir viewing ultra-spectral IR sounding of the lower atmosphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Infrared ultra-spectral spectrometers have brought in a new era in satellite remote atmospheric sounding capability. During the 1970s, after the implementation of the first satellite sounding instruments, it became evident that much higher vertical ...

Characterization and Meteorological Drivers of Dust Events Over California's Central Valley

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Dust events in California's Central Valley pose severe risks to public health, regional air quality, and transportation. Yet, the climatology and meteorological drivers of dust events in the region are poorly characterized due to sparse monitoring and limitations of satellite observations.

Theory of geostationary satellites

open access: yes, 1989
Geostationary or equatorial synchronous satellites are a daily reminder of our space efforts during the past two decades. The nightly television satellite weather picture, the intercontinental telecommunications of television transmissions and telephone ...

TEMPO Applications During Poor Wintertime Air Quality in Salt Lake City: An Analysis of Persistent Cold Air Pooling Events

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract During the wintertime, the Salt Lake Valley (SLV) experiences episodes of poor air quality during persistent cold air pools (PCAPs), wherein the atmospheric boundary layer remains stable for several days. We examine insights into the accumulation of primary emissions during PCAPs gained from NO2 tropospheric column abundances derived from ...

Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Improvement of orbit determination for geostationary satellites with VLBI tracking

open access: yes, 2011
China's COMPASS satellite navigation system consists of five or more geostationary (GEO) satellites. The roles of GEO satellites are to improve the regional user's positioning accuracy and provide the continuous Radio Determination Satellite Service. The

Satellite‐Based Global Assessment of Solar Resource Stability

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Satellite spatial smoothing complicates comparisons of solar variability between gridded products and point measurements. We introduce the Stability Deviation Index (SDI), a bounded composite of solar intensity and intraday variability. Applied independently to 69 BSRN stations and co‐located CERES grid cells, SDI shows strong cross‐platform ...
