Daily 0.1° Seamless XCH₄ Fusion Dataset over Six Continental Regions, 2018–2024
Listed in ScienceDB
This dataset provides daily 0.1° continuous XCH₄ fields from 2018 to 2024 over six representative continental regions: East Asia, North America, Europe, Africa, Australia, and South America.
Description
The dataset is primarily constrained by TROPOMI satellite observations and incorporates ERA5 meteorological variables. A self-supervised gated spatiotemporal convolution framework is used to reconstruct missing satellite observations.
CAMS-EGG4 complete XCH₄ fields and observation-derived TROPOMI masks are used for model training, while the final reconstruction is driven by TROPOMI observations, observation masks, a 30-day XCH₄ background field, and meteorological variables. The dataset can support analyses of regional methane variability, long-term trends, and methane enhancement patterns.
