A global near real-time dataset of Microwave Integrated Drought Index from the Fengyun-3 satellites.
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Droughts have become more frequent and intense with increasing climate warming, posing widespread risks on ecosystem, agricultural, and water resources, therefore effective and timely drought monitoring is critical to drought assessment, management, and mitigation. Here, we presented a global monthly and ten-day drought dataset of the Fengyun-3 Microwave Integrated Drought Index (FY-3 MIDI) by integrating the inconsistency corrected FY-3B/C/D derived microwave precipitation, soil moisture, and land surface temperature with optimal weights from June 2014 to present. The dataset was evaluated and validated against the Standardized Precipitation Evapotranspiration Index, the Self-calibrating Palmer Drought Severity Index, and the non-FY MIDI at 0.25°. The FY-3 MIDI can effectively observe drought condition and characteristics as captured by the reference datasets, and it was reliable in monitoring meteorological drought with the ability to work in all-weather condition. Based on the operational Fengyun-3 series satellite, it provided valuable operational service in near real-time on a monthly and ten-day time scale, guaranteeing present and future continuous applications to support global and regional drought monitoring and assessment.
