ChinaRiceCalendar is a raster dataset providing seasonal crop calendars for early, middle, and late rice in China at a 1-km spatial resolution. The dataset, derived from MODIS data products, includes calendar dates for detected rice pixels and county-level summaries across five periods from 2003 to 2022. It was authored by researchers including Jinyuan Liu and Hui Li and published in Earth System Science Data in 2024.
Use Cases
- Modeling rice phenology and yield based on seasonal calendar dates.
- Analyzing regional variations in rice cultivation practices based on county-level summaries.
- Studying long-term changes in rice planting schedules based on data spanning five periods from 2003 to 2022.
- Integrating crop calendar data with climate models based on the 1-km spatial resolution raster format.
Strengths
- Provides data at a 1-km spatial resolution.
- Covers five distinct time periods spanning from 2003 to 2022.
- Includes both pixel-level and county-level data products.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- The dataset's size and exact file formats are unknown, which may limit suitability assessment.
