Water Resources Research, Volume 62, Issue 1, January 2026.Abstract Drought significantly affects water resources, agriculture, energy, and ecosystems, revealing enduring socio‐economic vulnerabilities over the centuries. This review synthesizes a century of development and recent advances in drought research (1900–2023), drawing on a bibliometric analysis of over 152,000 peer‐reviewed publications. The review

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract During the T119 bistatic radar (BSR) experiment, the Cassini spacecraft observed a collection of lakes in Titan's Northern Lake District. Specular reflections from liquid surfaces were clearly detected at X‐band ground‐based station DSS‐43 (Canberra), spaced out by sudden drops of power in correspondence to solid terrains.

Theoretical study of ice cover phenology at large freshwater lakes based on SMOS MIRAS data [PDF]
The Cryosphere, 2018 The paper presents a theoretical analysis of seasonal brightness temperature variations at a number of large freshwater lakes: Baikal, Ladoga, Great Bear Lake (GBL), Great Slave Lake (GSL), and Huron, retrieved from Microwave Imaging Radiometer with ...

Remote Sensing of Live Fuel Moisture for Wildfires Using SMAP Satellite Observations
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Live Fuel Moisture (LFM) is a critical parameter for wildfire risk assessment, traditionally measured by labor‐intensive field sampling. However, sampled LFM data are influenced by site‐specific factors, such as local vegetation types and plant traits, and are often collected retrospectively after wildfire events, making it difficult to obtain

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.Abstract Using the recently available reanalysis data set JAWARA, which covers the whole middle atmosphere over a long period of 19 years from September 2004 to December 2023, four Rossby‐gravity and 10 Rossby normal modes have been identified. In the upper mesosphere, the geopotential height (GPH) amplitudes of all Rossby‐gravity modes are maximized ...

Analysis of a Least-Squares Soil Moisture Retrieval Algorithm from L-band Passive Observations
Remote Sensing, 2010 The Soil Moisture and Ocean Salinity (SMOS) mission of the European Space Agency (ESA), launched on November 2009, is an unprecedented initiative to globally monitor surface soil moisture using a novel 2-D L-band interferometric radiometer concept ...

A compact receiver system for simultaneous measurements of mesospheric CO and O3 [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2016 During the last decades, ground-based microwave radiometry has matured into an established remote sensing technique for measuring vertical profiles of a number of gases in the stratosphere and the mesosphere. Microwave radiometry is the only ground-based

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.In this paper, we compare atmospheric water vapour data acquired with lidars during the WaLiNeAs programme with data from the ECMWF ERA5 reanalysis. The WaLiNeAs field measurement campaigns took place in autumn/winter 2022/2023 over the French Mediterranean basin and in summer 2023 near Toulouse.

Diurnal variations in middle-atmospheric water vapor by ground-based microwave radiometry [PDF]
Atmospheric Chemistry and Physics, 2013 In this paper, we compare the diurnal variations in middle-atmospheric water vapor as measured by two ground-based microwave radiometers in the Alpine region near Bern, Switzerland.

Adaptive filter for microwave radiometry
Electronics Letters, 1970 An adaptive filter, which combines the advantages of both short (about 0.5 s) and long (about 2 min) integrating time constants, is described. The recording time constant will be long for a steady level of input signal, but will proportionally shorten when there is a change in the average level of the input signal. If steady conditions continue after a
