ASCAT Wind Superobbing Based on Feature Box [PDF]

Advances in Meteorology, 2018
Redundant observations impose a computational burden on an operational data assimilation system, and assimilation using high-resolution satellite observation data sets at full resolution leads to poorer analyses and forecasts than lower resolution data sets, since high-resolution data may introduce correlated error in the assimilation.

Deriving Gridded Soil Moisture Estimates Using Earth Observation Data and a Process Informed Statistical Machine Learning Approach

Meteorological Applications, Volume 33, Issue 1, January/February 2026.
A process‐informed machine learning approach, which included dynamic and static earth observation data and trained on in situ data from the United Kingdom, was capable of reproducing measured in situ values from locations not included in the model training. The model was then employed to derive daily, gridded estimates of soil moisture for Ireland. The

Correction of ASCAT, ESA–CCI, and SMAP Soil Moisture Products Using the Multi-Source Long Short-Term Memory (MLSTM)

Remote Sensing
The Advanced Scatterometer (ASCAT), Soil Moisture Active Passive (SMAP), and European Space Agency-Climate Change Initiative (ESA–CCI) soil moisture (SM) products are widely used in agricultural drought monitoring, water resource management, and climate ...

The ASCAT 6.25-km Wind Product

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
The advanced scatterometer (ASCAT) wind data processor (AWDP) produces ocean surface vector winds from radar measurements by the ASCAT on board the Metop satellites. So far, the ASCAT-coastal product with a grid size of 12.5 km has been the one with the highest resolution.

Land data assimilation of satellite‐based surface soil moisture: Impact on atmospheric simulations over the contiguous United States

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 775, January 2026 Part B.
Soil Moisture Active Passive soil moisture retrievals are assimilated into a land surface model and the resulting land reanalysis product is used to initialise the land component of coupled land‐atmosphere experiments. We show that the local impact of land data assimilation on the atmosphere is influenced by two factors: the magnitude by which it ...

Evaluating the impact of satellite soil moisture data as an additional component in the calibration of a conceptual hydrological model

Journal of Hydrology and Hydromechanics
This study proposes a new method for dividing a catchment with the aim of testing it in the calibration process of a conceptual hydrological model. The new catchment division is reflected in having different land cover zones and the input data prepared ...

An evaluation of ASCAT surface soil moisture products with in-situ observations in Southwestern France [PDF]

Hydrology and Earth System Sciences, 2009
A long term data acquisition effort of profile soil moisture is currently underway at 13 automatic weather stations located in Southwestern France. In this study, the soil moisture measured in-situ at 5 cm is used to evaluate the normalised surface soil ...

Characterizing Buoy Wind Speed Error in High Winds and Varying Sea State with ASCAT and ERA5

Remote Sensing, 2021
Buoys provide key observations of wind speed over the ocean and are routinely used as a source of validation data for satellite wind products. However, the movement of buoys in high seas and the airflow over waves might cause inaccurate readings, raising
