Dynamic Bayesian Nonlinear Calibration [PDF]

open access: yes, 2014
Statistical calibration where the curve is nonlinear is important in many areas, such as analytical chemistry and radiometry. Especially in radiometry, instrument characteristics change over time, thus calibration is a process that must be conducted as ...

Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

open access: yesAdvanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

Experimental assessment of large mammal population estimates from airborne thermal videography

open access: yesWildlife Biology, EarlyView.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.

Lead and Floe Detection From CryoSat‐2 Radar and ICESat‐2 Laser Altimetry

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Differences in satellite sampling affect their ability to resolve small‐scale features over Arctic sea ice. For CryoSat‐2 (CS2) and ICESat‐2 (IS2) these differences are driven by geometric (footprint resolution) and radiometric (radar or laser) sampling.

The Characteristics of Pekeris Modes Revealed by Long‐Term Reanalysis Data JAWARA Covering the Entire Middle Atmosphere

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract The characteristics of Pekeris modes as well as Lamb modes are investigated using the new reanalysis data set JAWARA, which spans over 19 years and covers the entire middle atmosphere. Pekeris modes are a class of global normal modes whose energy is trapped in two height regions that is, around the stratopause and the surface, while the energy
