Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Forecasting Climate Change Using a Multivariate Cointegrated System

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT A cointegrated vector equilibrium correction model of key climate variables including sea surface temperature, ocean heat content, Arctic sea‐ice extent and sea‐level change is built, driven by radiative forcing in which a stochastic trend arises due to anthropogenic emissions of greenhouse gases.

Optical Properties and Possible Origins of Atmospheric Aerosols over LHAASO in the Eastern Margin of the Tibetan Plateau

open access: yesRemote Sensing
The accuracy of cosmic ray observations by the Large High Altitude Air Shower Observatory Wide Field-of-View Cherenkov/Fluorescence Telescope Array (LHAASO-WFCTA) is influenced by variations in aerosols in the atmosphere.

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Retrieving Aerosol Optical Depth over Land from Landsat-8 Satellite Images with the Aid of Cloud Shadows

open access: yesRemote Sensing
Clouds and their shadows can be clearly identified from high-spatial-resolution satellite images, such as those provided by Landsat-8/9 with a spatial resolution of approximately 30 m and Sentinel-2 with a spatial resolution of around 20 m. Consequently,

Measurement and modeling of diffuse ultraviolet radiation: A review

open access: yesPhotochemistry and Photobiology, EarlyView.
Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.
