An Intercomparison of Changes Associated with Earth's Lower Tropospheric Temperature Using Traditional and AMIP-Style Reanalyses [PDF]

Reanalyses have become an integral tool for evaluating regional and global climate variations, and an important component of this is modifications to the energy budget.

The Use of MERRA-2 Near Surface Meteorology to Understand the Behavior of Planetary Boundary Layer Heights Derived from Wind Profiler Data over the US Great Plains [PDF]

The atmospheric general circulation model (GCM) that underlies the MERRA-2 reanalysis includes a suite of physical parameterizations that describe the processes that occur in the planetary boundary layer (PBL).

Concurrent Variations in Air–Sea Heat Fluxes and Sea Ice Extensions Under Cold‐Air Outbreaks: The First Joint Buoy–Cruise Observational Results in the Bohai Sea

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The air–sea interface near seasonal ice edges notably regulates the regional climate but remains poorly understood. We present the first coordinated buoy–cruise measurements in the Bohai Sea—the world's lowest‐latitude seasonal ice zone—during the winter of 2024–2025.

Strong Ventilation Drives the Aerosol Pollution Receptor Center and Its Interannual Variability in Central China's Twain‐Hu Basin

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study investigates the unique winter phenomenon in central China's Twain‐Hu Basin where high aerosol optical depth (AOD) centers coincide with a regional near‐surface wind speed maximum. Based on multi‐decadal reanalysis data sets, satellite retrievals, ground observations, and FLEXPART‐WRF simulations, we demonstrate that strong ...

Testing of the LSST's photometric calibration strategy at the CTIO 0.9 meter telescope [PDF]

, 2018
The calibration hardware system of the Large Synoptic Survey Telescope (LSST) is designed to measure two quantities: a telescope's instrumental response and atmospheric transmission, both as a function of wavelength.

Making a Dust Source Map: Can We Build, Implement, and Learn From a Reflectance Derived Sediment Supply Map in the Unified Forecast System (UFS)?

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Mineral dust is an important part of the climate system we live in. Dust hotspots in deserts and arid regions emit tons of dust annually, influenced by local meteorology and soil characteristics. As one of the most abundant aerosols, it is important to characterize and define the climate and human impacts of dust.

Ground‐Based Microwave Measurements of ClO and O3 Over Scott Base, Antarctica

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract We present measurements from a new microwave instrument that has been deployed at Scott Base, Antarctica, primarily to measure ClO. The new instrument allows for the extension of the time series of lower stratospheric ClO measurements begun in 1996 at this site, while some of the technical improvements offer the possibility of making ...
