Water Resources Research, Volume 62, Issue 9, September 2026.Abstract Reservoir hypsometric relationships are crucial in determining water storage changes and modeling hydrological processes. Previous studies have demonstrated that uncertainties in reservoir surface area observations are a primary source of error in satellite‐derived storage estimates.

Land Degradation &Development, Volume 37, Issue 14, Page 10127-10146, 30 August 2026.ABSTRACT The spatio‐temporal relationship between Forest Canopy Structure (FCS) and Belowground Biomass Carbon (BGBC) is fundamental to determining how optimizing spatial structure can maximize forest carbon‐sink potential in land management. However, the lidar data resolution over the space and time exists limitation, causing the coupling relationship

Surface Clutter Suppression Techniques for Ice Sounding Radars: Analysis of Airborne Data [PDF]
, 2008 For the ice sounding of Antarctica from space, a P-band radar at 435 MHz is the only option which complies with present ITU regulations. At this frequency the ice surface cannot be considered smooth, leading to high ambiguous returns.

The Role of Lightning in Atmospheric Chemistry
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...
