Reconstruction of Sentinel-2 Image Time Series Using Google Earth Engine

open access: yesRemote Sensing, 2022
Sentinel-2 NDVI and surface reflectance time series have been widely used in various geoscience research, but the data is deteriorated or missing due to the cloud contamination, so it is necessary to reconstruct the Sentinel-2 NDVI and surface ...

Effects of amendments on carbon and nitrogen fractions in agricultural soils of Yellow River Delta

open access: yesGeoscience Letters, 2023
Although various measurements (including organic amendments) have been used to ameliorate saline–alkaline soils, soil organic matter (SOM) remains low in most salt-affected agriculture soils.

Multi-objective parameter optimization of common land model using adaptive surrogate modeling [PDF]

open access: yesHydrology and Earth System Sciences, 2015
Parameter specification usually has significant influence on the performance of land surface models (LSMs). However, estimating the parameters properly is a challenging task due to the following reasons: (1) LSMs usually have too many adjustable ...

Responses of soil organic and inorganic carbon to organic and phosphorus fertilization in a saline − alkaline paddy field

open access: yesGeoscience Letters, 2023
There is evidence of increased soil organic carbon (SOC) and inorganic carbon (SIC) under fertilization in dry croplands of arid and semi-arid areas. However, not much is known about the responses of SOC and SIC in coastal saline − alkaline paddy soils ...

Trend Changes of the Vegetation Activity in Northeastern East Asia and the Connections with Extreme Climate Indices

open access: yesRemote Sensing, 2022
In the context of global warming, vegetation activity in northeastern East Asia (40–45°N, 105–130°E) (NEA) shows a significant growth trend on a multidecadal scale, but how vegetation changes on a decadal scale is unclear.
