Digital Earths webinar series on high-resolution land model and land-atmosphere coupling aims to establish a platform for ongoing dialogue among researchers focusing on km-scale climate system models, with a particular emphasis on integrating land-surface processes and land-atmosphere interactions, especially hydrological cycles. The series is co-convened by Min-Hui Lo (National Taiwan University), Andy Newman (NCAR), Yifan Cheng (NCAR), and Andrew Gettelman (PNNL).
