Monsoon Asia Rice Calendar (MARC): a gridded rice calendar in monsoon Asia based on Sentinel-1 and Sentinel-2 images

This dataset is a gridded (0.5 degree) rice calendar in monsoon Asia based on Sentinel-1 and Sentinel-2 satellite images. The dataset uses the feature-based algorithm (Zhao et al., 2023) to extract the rice transplanting and harvest date, as well as the fitted Weibull function to recognize the number of rice cropping automatically. The variation of transplanting and harvest dates was calculated by the 3 × 3 pixel window over the year 2019 and 2020 using von Mises method. This dataset provides two types of rice calendar: group-based and grid-based rice calendar, and the variation of these two rice calendars, respectively.
