Spaceborne Synthetic Aperture Radar for Oceanography

Eos, Transactions American Geophysical Union, 1982
The book originates from a symposium held at the Applied Physics Laboratory of the Johns Hopkins University in March 1980. The purpose of the symposium was to review the results to date of investigations related to the SEASAT SAR (synthetic aperture radar) experiment and, to quote from the book's foreword, ‘to explore the potential’ of such satellite ...

Radar First Echo Detection With Spaceborne Precipitation Radars

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract The radar “first echo” appears in a fresh growing cloud when hydrometeors grow to large enough sizes to be detected by radar. Using 26‐year observations by the Ku band radars onboard the Global Precipitation Mission and the Tropical Rainfall Measurement Mission satellites, isolated pixels with detectable radar echoes at altitude and without ...

Influence of Cloud Microphysical Properties on Airborne Lidar Measurements: Results From the IMPACTS Field Campaign

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.
Abstract Ice‐ and mixed‐phase clouds play an important role in the global radiative budget and hydrological cycle, yet the complexity of ice crystal shapes and the presence of supercooled liquid water (SCLW) present challenges for retrieving cloud properties from airborne and spaceborne remote sensing instruments.

Observing glacier elevation changes from spaceborne optical and radar sensors – an inter-comparison experiment using ASTER and TanDEM-X data [PDF]

The Cryosphere
Observations of glacier mass changes are key to understanding the response of glaciers to climate change and related impacts, such as regional runoff, ecosystem changes, and global sea level rise.

Sentinel‐1 SAR Estimates of Snowmelt Onset Coincide With SNOTEL Soil Moisture Pulses Across the Western United States

Hydrological Processes, Volume 39, Issue 12, December 2025.
This study integrates repeated in situ measurements, data from 260 SNOw TELemetry (SNOTEL) stations, and paired Sentinel‐1 SAR observations across the Western United States to assess snowpack evolution prior to and after Sentinel‐1 SAR‐derived snowmelt runoff onset.

The Climatic Impacts of a Satellite‐Based Parameterization of the Wegener‐Bergeron‐Findeisen Process for Large‐Scale Models

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract A satellite‐based temperature‐dependent parameterization of the Wegener‐Bergeron‐Findeisen (WBF) process that takes into account the subgrid‐scale variability of cloud thermodynamic phase within mixed‐phase clouds is developed and implemented in version 5.3 of the Community Atmosphere Model (CAM5.3).
