Forecast of Spectral Features by Ensemble Data Assimilation

Frontiers in Applied Mathematics and Statistics, 2018
Data assimilation permits to compute optimal forecasts in high-dimensional systems as, e.g., in weather forecasting. Typically such forecasts are spatially distributed time series of system variables. We hypothesize that such forecasts are not optimal if

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

Advanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

2‐line Ferrihydrite Enhance Microbial Synthesis of Plant Biostimulants in Composted Biosolid by Regulating Phyla Pseudomonadota and Actinomycetota

Advanced Science, EarlyView.
This study explores how iron and manganese oxides transform sewage sludge into plant biostimulants during composting. Non‐targeted identification reveals the main species of plant biostimulants. Metagenomic analysis reveals that 2‐line ferrihydrite specifically enriches microbial genes for biosynthesis, boosting plant‐growth promoters.

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

Impact of the One-Stream Cloud Detection Method on the Assimilation of AMSU-A Data in GRAPES

Remote Sensing, 2020
Clouds affect the assimilation of microwave data from satellites and therefore the detection of clouds is important under both clear sky and cloudy conditions.

U‐Shaped Response of Flowering Time to Low and High Nitrogen via a Transcription Feedback Loop in Rice

Advanced Science, EarlyView.
The “seesaw effect” of Nhd1‐Ghd7 module in regulating flowering time (days to heading in rice) responses to nitrogen (N) via Hd3a/RFT1: deficient‐N (DN) delays flowering via Ghd7‐mediated suppression of Nhd1; moderate‐N (MN) impairs this suppression, enhancing Nhd1 to promote flowering; whereas superior‐N (SN) delays flowering by Nhd1‐activated ...
