AMSR-E melt patterns on the Southern Patagonia Icefield [PDF]

Journal of Glaciology, 2010
AbstractPassive-microwave 37 GHz vertically polarized (V) brightness temperature (Tb) measurements from the Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) are used to monitor the extent and timing of snowmelt on the Southern Patagonia Icefield (SPI) in Chile and Argentina. Twice daily Tb’s for 2002–08 for high-elevation (>

Towards improving Arctic mixed‐phase cloud representation in the ECMWF model using MOSAiC observations

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 779, July 2026 Part B.
Abstract The presence of Arctic clouds plays a crucial role in the evolution of the surface temperature of Arctic sea ice. However, large biases in cloud representation remain in state‐of‐the‐art weather and climate models. In this study, we use observational data from the one‐year Arctic ship campaign Multi‐disciplinary drifting Observatory for the ...

Improving cold-region streamflow estimation by winter precipitation adjustment using passive microwave snow remote sensing datasets

Environmental Research Letters, 2021
Winter precipitation estimations and spatially sparse snow observations are key challenges when predicting snowmelt-driven floods. An improvement in streamflow prediction is achieved in a snowmelt-dominant basin, i.e.

National Oceanic and Atmospheric Administration Soil Moisture Operational Product System: An overview and data assimilation applications

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract National Oceanic and Atmospheric Administration–National Environmental Satellite, Data, and Information Service (NESDIS) developed the Soil Moisture Operational Product System (SMOPS) to serve as a one‐stop shop for all available microwave satellite soil moisture observations.

The merging of radiative transfer based surface soil moisture data from SMOS and AMSR-E

, 2017
This paper evaluates a methodology to integrate surface soil moisture retrievals from SMOS and AMSR-E into a single, consistent dataset retrieved by the Land Parameter Retrieval Model (LPRM).

Antarctic summer sea ice concentration and extent: comparison of ODEN 2006 ship observations, satellite passive microwave and NIC sea ice charts [PDF]

The Cryosphere, 2009
Antarctic sea ice cover has shown a slight increase (<1%/decade) in overall observed ice extent as derived from satellite mapping from 1979 to 2008, contrary to the decline observed in the Arctic regions.

On the Importance of the Jacobian of a DNN Observation Operator in Land Data Assimilation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract A recent study (Shan et al., 2024, https://doi.org/10.1016/j.rse.2024.114167) showed that using a Deep‐Neural‐Network (DNN)‐based observation operator in land data assimilation (DA) does not guarantee improvements in surface soil moisture (WG2).

Soil Moisture Impact on Convective Initiation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The influence of soil moisture on convective storm initiation remains an open question, with previous studies showing conflicting results regarding whether storms preferentially form over wet or dry soils. Here, we analyze the soil moisture‐convection relationship using satellite observations across North America, Africa, and Australia from ...

Dynamic Decomposition of Sub‐Daily Antarctic Sea‐Ice Concentration Change Using Passive Microwave Swath Observations

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Spaceborne radiometers have enabled global sea‐ice distribution observations since 1978, yet design choices associated with conventional daily averaged remote sensing products mean they do not resolve higher‐frequency variability that characterizes Antarctic sea ice.
