2026-08-19 Daily-scale multi-layer soil moisture dataset for the black soil region in Northeast China (2008-2023) doi:10.57760/sciencedb.iga.0016f en a. Data content (data file/table name, including observation indicator content) This dataset encompasses daily-scale multi-layer soil moisture data for the black soil region of Northeast China spanning from 2008 to 2023, offering data support for research on agricultural drought and waterlogging in the black soil region. b. Construction purpose The frequent occurrence of droughts and waterlogging in Northeast China poses a threat to food security. Since soil moisture is one of the important factors contributing to agricultural droughts and waterlogging, there is an urgent need to study the impact of agricultural droughts and waterlogging on crops in the black soil region of Northeast China by constructing a soil moisture dataset. c. Service recipients It can be widely used by scientific researchers and students in agriculture, ecological environment, hydrology, wetland ecology, and other related disciplines. d. Time range of data 2008-2023 e. Spatial scope of data Northeast black soil region f. Data projection method Projected Coordinate System：Krasovsky_1940_Albers Geographic Coordinate System：GCS_Krasovsky_1940 g. Disciplinary scope of data Earth Sciences > Geography > Physical Geography h. Amount of data The total data volume is approximately 168GB black soil region in Northeast; multi-layer soil moisture; 2008-2023 Zhu Bing-xue PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
