Dr. Yan Nana currently is an associate professor of Aerospace Information Research Institute (AIR), Chinese Academy of Sciences (CAS). Her research interests are remote sensing applications in agriculture and water resources, including drought monitoring and assessment, evapotranspiration monitoring, crop water productivity and water saving assessment. She developed the national drought monitoring system in 2006 and continually provides the ten-days/seasonal bulletin for different departments of governments. As a core member of ETWatch team, she participates in the ET model developing, ETwatch system construction and ET data analysis and applications. She has published 4 monographs and more than 80 peer-reviewed papers.
