Towards the Removal of Model Bias from ESA CCI SM by Using an L-Band Scaling Reference

open access: yes2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Constructing long time records of soil moisture (SM) requires the merging of data derived from different instruments while insuring the removing of the bias from different sensors time series. For instance, the ESA Climate Change Initiative (CCI) for SM currently uses the GLDAS v2.1 model as the reference to re-scale active and passive microwave time ...

Prolonged duration and increased severity of agricultural droughts during 1978 to 2016 detected by ESA CCI SM in the humid Yunnan Province, Southwest China

CATENA, 2021
Abstract Droughts in humid regions may have more severe consequences owing to a lack of drought-resistant measures and awareness. The Yunnan Province, in the humid southwestern part of China, experienced an extreme drought from 2009 to 2010. However, few studies have systematically explored agricultural droughts in this region.

ESA CCI SM v9: advancements in global satellite soil moisture records

Soil moisture plays a pivotal role in the Earth system, exerting a profound impact on a wide range of environmental and climatic processes. Consequently, accurate monitoring of soil moisture is essential for climate research, environmental management, and the development of adaptation strategies under changing climate conditions.

The ESA CCI SM Freeze/Thaw Product: Global detection of frozen grounds from 1987 to the present 

The ESA CCI Soil Moisture product provides a global long-term consistent data record of soil moisture from 1978 up to the present day. It is produced by fusing measurements from a total of 19 both passive and active satellite microwave observations. Determining the physical state of water in the soil is crucial for this product, as retrievals of soil ...

Random Forest Prediction and Validation of Soil Moisture in Eastern Africa Using ESA CCI SM and ISMN In-Situ Observations

Structural breaks and reduced ground station coverage have previously limited soil moisture (SM) analyses and validation approaches over Eastern Africa. Due to its high dependence on rain-fed agriculture, it is vital to analyze SM variability and establish reliable monitoring frameworks for the region.

A gap-filled global long-term satellite soil moisture climate data record from ESA CCI SM

ESA CCI Soil Moisture is a multi-satellite climate data record that consists of harmonized, daily observations coming at present from 19 satellites operating in the microwave domain. The wealth of satellite information, particularly over the last decade, facilitates the creation of a data record with the highest possible data consistency and coverage ...
