Extending reliability to intensive longitudinal data with the Kalman filter
British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 493-512, November 2026.Abstract Reliability is central to how researchers approach measurement in standard, group‐based analyses of single‐time‐point data, yet this critical aspect is often overlooked in the analysis of repeated observations. Since its inception, reliability has been a between‐person concept, but we redevelop this notion for within‐person designs by ...

Interference and Multipath Resilient ToA Estimation
2025 59th Asilomar Conference on Signals, Systems, and ComputersWe present a computationally-efficient algorithm for time-of-arrival (ToA) estimation that is robust under multipath propagation and strong interference. Our algorithm leverages multiple receive antennas to combine adaptive spatial filtering with autodifferentiation in order to super-resolve the tap of the first-arriving path at low computational ...

The Climatological ITCZ Location Modulates Extratropics‐to‐Tropics Teleconnections
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract While extratropical forcing has far‐reaching effects through teleconnections, the Intertropical Convergence Zone (ITCZ) has been shown to partly block the propagation of extratropical perturbations to the opposite hemisphere. However, the influence of the ITCZ location on the tropical response and the blocking effect remain poorly understood ...

Longwave Scattering Effects on Radiative Kernels
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.Abstract Longwave (LW) scattering, the redirection of infrared radiation by cloud and aerosol particles, is often neglected in current global climate models (GCMs). However, studies have suggested that LW scattering can influence the Earth's energy budget and climate sensitivity, indicating a need to improve the representation and understanding of this

Remote Sensing, 2019 Knowledge of key variables driving the top of the atmosphere (TOA) radiance over a vegetated surface is an important step to derive biophysical variables from TOA radiance data, e.g., as observed by an optical satellite.

Improved Estimates of Equilibrium Climate Sensitivity From Non‐Equilibrated Climate Simulations
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.Abstract Calculating equilibrium climate sensitivity (ECS) requires simulations of a thousand years or more for the climate to re‐establish equilibrium, but most ECS estimates are derived from shorter model integrations. The widely used “Gregory method” for such estimates systematically underestimates ECS, a bias previously attributed to the time ...
