Abstract Soil moisture (SM) plays a key role in land-atmosphere (L-A) interaction and can affect subsequent precipitation (P) from local to regional scale. Due to complexity of L-A interactions, multiplicity of SM-P interaction, limitations of SM observations (spatial and temporal coverage and resolution) and parameter dependency of model-based studies, findings are uncertain and inconclusive. High-resolution soil moisture observations open new possibilities for understanding SM-P interactions in finer scale while overcoming limitations of observations and model studies. On the other hand, differentiating between “local recycling” and “regional advecting” regions for evaporated moisture are important when grid cells become smaller enough for the moisture to advect over the cell boundary within current temporal resolutions. Thereby SM can influence subsequent precipitation significantly beyond the local boundary. This study shows that SM correlates better with neighboring region compared to local, and the influence of features such as topography and wind modulate the behavior.
