A Search for the Near‐Surface Particulate Layer Using Venera 13 In Situ Spectroscopic Observations

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Whether or not there is a particulate layer in the lowest 10 km of the Venusian atmosphere is still an open question. Some of the past in situ experiments showed the presence of a detached particulate layer, and a few suggested the existence of finely dispersed aerosols, while other instruments supported the idea of no particulate matter in ...

Streamflow Monitoring at High Temporal Resolution Based on Non‐Contact Instruments and Manually Surveyed Bathymetry in a River Prone to Bathymetric Shifts

Water Resources Research, Volume 61, Issue 4, April 2025.
Abstract This study presents a proof of concept of a reliable methodology for monitoring streamflow in a dynamic river of the Alps prone to bathymetric changes using non‐contact instruments. The method relies on water level and surface velocity radar monitoring, discharge measurements by Large‐Scale Particle Image Velocimetry (LSPIV), and topographic ...

Freeze‐Up Ice Jams and Channel Hydraulics Cause Hazardous Open Water Zones Within Winter Ice Cover on the Kuskokwim and Yukon Rivers and Their Tributaries

Water Resources Research, Volume 61, Issue 4, April 2025.
Abstract Timing and completeness of freeze‐up on northern rivers impact winter travel and indicate responses to climate change. Open‐water zones (OWZs) within ice‐covered rivers are hazardous and may be increasing in extent and persistence. To better understand the distribution, variability, and mechanisms of OWZs, we selected nine reaches totaling 380

Distributed PMCW Radar Network in Presence of Phase Noise [PDF]

arXiv
In Frequency Modulated Continuous Waveform (FMCW) radar systems, the phase noise from the Phase-Locked Loop (PLL) can increase the noise floor in the Range-Doppler map. The adverse effects of phase noise on close targets can be mitigated if the transmitter (Tx) and receiver (Rx) employ the same chirp, a phenomenon known as the range correlation effect.
