Combined Retrieval of Cloud Parameters for TEMPO Measurements Over Canada Using Oxygen Dimer and B Band Absorption

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Tropospheric Emissions: Monitoring of Pollution (TEMPO) provides valuable hourly measurements of airborne pollutants over North America. Data quality over snowy surfaces may degrade due to difficulty in accurately characterizing surface reflectivity and cloud properties, as snow and cloud are both highly reflective and therefore challenging to

A Multiscale Investigation of Habitat Use and Within-river Distribution of Sympatric Sand Darter Species [PDF]

, 2018
The western sand darter Ammocrypta clara, and eastern sand darter Ammocrypta pellucida are sand-dwelling fishes of conservation concern. Past research has emphasized the importance of studying individual populations of conservation concern, while recent ...

The stratigraphy, correlation, provenance and palaeogeography of the Skiddaw Group (Ordovician) in the English Lake District [PDF]

, 1995
A new lithostratigraphy is presented for the Skiddaw Group (lower Ordovician) of the English Lake District. Two stratigraphical belts are described. Five formations are defined in the Northern Fells Belt, ranging in age from Tremadoc to early Llanvirn.

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 801-818, May 2026.
Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Anomalous Opaque Clouds Revealed by Collocated MODIS and CALIOP Retrievals

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This paper examines discrepancies between cloud optical thickness (COT) retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) cloud product, and cloud opacity measurements from the Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) lidar.

Guide to the geology of Bradgate Park and Swithland Wood, Charnwood Forest [PDF]

, 2010
Charnwood Forest is one of the few parts of England where there are exposures of ‘basement’ rocks dating back to Precambrian time. Its locally rugged topography is caused by these highly resistant rocks protruding as craggy knolls through a surrounding ...

Hump‐Shaped Enhancement of Coarse‐Grain Transport in Sediment Mixtures Induced by Fine Grains of Different Sizes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bedload transport of sediment mixtures is fundamental to river morphology and impacts aquatic ecology. Adding fine grains enhances coarse‐grain transport, yet controlling mechanisms remain elusive. Employing discrete element simulations, we examine how fine‐grain size and proportion influence coarse‐grain flux.

The geology of the St. Helens-Scamander area, Tasmania [PDF]

, 1957
The Scamander Slate and Quartzite consist essentially of a succession of stratified slates, quartzites and sub-greywackes with a few siltstone bands, which probably form part of the Mathinna Group.

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.
