Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.Abstract Mixed‐phase clouds modulate the water and energy cycles of high‐latitude regions, yet their liquid‐ice phase partitioning has long been poorly simulated in climate models. Here, simulations of Arctic mixed‐phase clouds by the Simple Cloud‐Resolving E3SM Atmosphere Model (SCREAM) are assessed against large‐eddy simulations, satellite data, and ...

Position determination of acoustic source using a discrete probability density method supported by joint detection and time of arrival estimation [PDF]
Scientific Technical Review, 2017 The localization of various acoustic sources in a battlefield (such as weapon rounds, mortars, rockets, mines, improvised explosive devices, vehicle-borne improvised explosive devices and airborne vehicles) nowadays has significant history.

Room geometry estimation from a single channel acoustic impulse response [PDF]
, 2013 For a 2D rectangular room of unknown dimensions and with unknown source and microphone positions, the times of arrival of reflections can be described in terms of im-age source positions.

Non-line-of-sight Node Localization based on Semi-Definite Programming in Wireless Sensor Networks
, 2009 An unknown-position sensor can be localized if there are three or more anchors making time-of-arrival (TOA) measurements of a signal from it. However, the location errors can be very large due to the fact that some of the measurements are from non-line ...

The Impact of Horizontal Resolution on Surface Irradiance Over Land in km‐Scale Earth System Models
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.Abstract Storm‐resolving global climate models, approaching km‐scale grid spacings, are slowly emerging. With increasing horizontal resolution, we expect improvements in the surface radiation budget because (a) synoptic variability may be better represented, (b) convective systems are better resolved, and (c) landscape heterogeneity is represented in ...

Engineering Of Acoustic Technology For Underwater Positioning Object [PDF]
, 2018 Underwater Positioning System (UPS) is a system to track the existence of the position of an object by utilizing the arrival time of the signal measurement. On land, the system uses an electromagnetic signal called GPS.

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.High‐resolution PlanetScope imagery reveals seasonal variations in proglacial lake area are underestimated by ~7% in moderate‐resolution data, while use of a single summer image can underestimate annual maximum area by ~2%. Capturing these seasonal variations provides valuable insights into the factors driving lake dynamics at Fjallsárlón, Iceland ...
