15 25V Power Supply With Preregulator Lingling Liu supports the use of Earth observation (EO) data for ecosystem service assessments. Specifically, she works on several projects identifying the solutions to using EO products in InVEST. Lingling previously worked as a postdoctoral fellow at the Geospatial Sciences Center of Excellence (GSCE) of the South Dakota State University (SDSU), where she focused on development and evaluation of a VIIRS global land surface phenology product for NASA. Lingling earned her Ph.D. in cartography and Geographic information system (GIS) from the Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences (CAS). Her research interests include the confluence of geography, remote sensing and GIS, land surface phenology and land surface dynamics and its response to global environmental change.
