%X Winter clover crops such as winter wheat, winter barley, winter rye, and clover play an important role in human diet and are grown around the world. Therefore, accurate spatial distribution information of winter clover crops is crucial for monitoring crop production and food security. However, due to the dependence of existing crop mapping methods on training samples, their application on a global scale is limited, resulting in a lack of high-resolution winter clover crop maps worldwide. Based on this new method, we have drawn for the first time a global 30 meter resolution distribution map of winter grass crops from 2017 to 2022. The time scale of this dataset is from 2017 to 2022, with a time resolution of years and a spatial resolution of 30m. The high-resolution global distribution map of winter grass crops is expected to provide support for various agricultural applications.
