Time Series Consistency of Passive Microwave Sensors (1978–2023) Brightness Temperature Data for Snow Depth Estimation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Passive microwave remote sensing offers all-weather, all-day observations, but sensor inconsistencies hinder long-term continuity and multisensor integration for surface parameters estimation. This study proposed methods to improve brightness temperature

Microwave Radiometer (MWR) Handbook [PDF]

, 2006
The Microwave Radiometer (MWR) provides time-series measurements of column-integrated amounts of water vapor and liquid water. The instrument itself is essentially a sensitive microwave receiver. That is, it is tuned to measure the microwave emissions of the vapor and liquid water molecules in the atmosphere at specific frequencies.

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, EarlyView.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Enhanced Full Spectral Temperature‐Dependent Refractive Index of Liquid Water From Supercooled to Ambient Conditions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract A new compilation of the complex refractive index of liquid water is presented, spanning temperatures from 240 $240$ (near homogeneous freezing) to 300 $300$ K and wavelengths from 0.034 $0.034$ μm to 10 m. The real part of the refractive index is derived using the Kramers–Kronig relation, where the imaginary part is constrained by ...

Observation of Mountain Waves and Secondary Gravity Waves in the Mesosphere Lower Thermosphere Above Patagonia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We find observational evidence for mountain waves (MWs) and secondary gravity waves (2GWs) in the OH*(3‐1) layer above Tierra del Fuego, Argentina. On the night of 21–22 May 2018, the Advanced Mesospheric Temperature Mapper (AMTM) obtained temperatures at ∼84 ${\sim} 84$ km.
