Global variation of meteor trail plasma turbulence [PDF]
Annales Geophysicae, 2011 We present the first global simulations on the occurrence of meteor trail plasma irregularities. These results seek to answer the following questions: when a meteoroid disintegrates in the atmosphere, will the resulting trail become plasma turbulent ...

Constraining Greenhouse Gas Cycling and Emissions in Africa's Largest Humic Lake
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.Abstract Humic tropical lakes and wetlands are globally important sources of atmospheric greenhouse gases (GHGs). However, mechanistic insight into GHG cycling in such systems remains limited—especially in understudied central Africa. To address this, here we measured high‐, falling‐, and low‐water seasonal concentrations and isotopic compositions of ...

Space Weather, Volume 24, Issue 3, March 2026.Abstract Modeling the high‐latitude ionosphere‐thermosphere system is imperative to understanding the impacts of space weather on modern technology, such as communications and navigation systems. At low‐ and mid‐latitudes, physics‐based and empirical models are well‐developed and capture the variability of the ionosphere to a good degree of accuracy ...

Radiant measurement accuracy of micrometeors detected by the Arecibo 430 MHz Dual-Beam Radar [PDF]
Atmospheric Chemistry and Physics, 2004 Precise knowledge of the angle between the meteor vector velocity and the radar beam axis is one of the largest source of errors in the Arecibo Observatory (AO) micrometeor observations. In this paper we study ~250 high signal-to-noise ratio (SNR) meteor

Combination of mesoscale and synoptic mechanisms for triggering an isolated thunderstorm: Observational case study of CSIP IOP 1 [PDF]
, 2007 Copyright @ 2007 AMSAn isolated thunderstorm formed in the southern United Kingdom on 15 June 2005 and moved through the area where a large number of observational instruments were deployed as part of the Convective Storm Initiation Project.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract The mesospheric semiannual oscillation (MSAO) in tropical zonal‐mean zonal winds exhibits a strong westward phase around March equinox. It has been thought that the migrating diurnal tide (DW1) plays a role in the initiation of this phase because DW1 peaks around this time and satellite observations have shown it to undergo wave breaking.

Shrunken Locally Linear Embedding for Passive Microwave Retrieval of Precipitation [PDF]
, 2014 This paper introduces a new Bayesian approach to the inverse problem of passive microwave rainfall retrieval. The proposed methodology relies on a regularization technique and makes use of two joint dictionaries of coincidental rainfall profiles and ...

Temperatures Using radar‐meteor decay times [PDF]
Geophysical Research Letters, 1999 Experimental studies of the temperature and pressure dependence of the ambipolar diffusion coefficient in the mesopause region have been undertaken by studying meteor trail decay times with radars at a variety of sites in North America, with latitudes between 75N and 35N.

Determination of meteoroid physical properties from tristatic radar observations [PDF]
Annales Geophysicae, 2008 In this work we give a review of the meteor head echo observations carried out with the tristatic 930 MHz EISCAT UHF radar system during four 24 h runs between 2002 and 2005 and compare these with earlier observations.
