A Statistically Modelling Method for Performance Limits in Sensor Localization
, 2011 In this paper, we study performance limits of sensor localization from a novel perspective. Specifically, we consider the Cramer-Rao Lower Bound (CRLB) in single-hop sensor localization using measurements from received signal strength (RSS), time of ...

Understanding the Climate Response to Different Vertical Patterns of Radiative Forcing
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract The dependence of climate response on the vertical structure of radiative forcing is studied using a set of idealized experiments, with horizontally uniform and vertically confined forcings. We find for a given effective forcing magnitude, higher‐altitude forcing causes a smaller global warming, owing to more negative cloud feedback.

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Observations reveal significant negative trends in reflected shortwave radiation over the 21st century. The global‐mean darkening is primarily driven by clouds, while the global‐mean atmospheric clear‐sky signal is near zero due to offsetting trends in the two hemispheres.

Artificial Neural Network for Location Estimation in Wireless Communication Systems
Sensors, 2012 In a wireless communication system, wireless location is the technique used to estimate the location of a mobile station (MS). To enhance the accuracy of MS location prediction, we propose a novel algorithm that utilizes time of arrival (TOA ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.Abstract This study uses a convection‐permitting model simulation to describe the environmental conditions under which convective upscale growth occurs in central Argentina, particularly examining environmental parameters when deep convection initially forms that could differentiate the rate of initial upscale growth.

Multi Detector Fusion of Dynamic TOA Estimation using Kalman Filter
, 2015 In this paper, we propose fusion of dynamic TOA (time of arrival) from multiple non-coherent detectors like energy detectors operating at sub-Nyquist rate through Kalman filtering.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.Abstract Accurate retrieval of satellite‐derived aerosol optical depth (AOD) is critical for air quality forecasting, especially when AOD is assimilated into models. However, if retrieval errors in the satellite‐derived AOD are not corrected or characterized, they can lead to false analysis increments and ultimately degrade the quality of data ...
