Dr. Ge Peng is currently a Senior principal research scientist from the University of Alabama in Huntsville (UAH), supporting the NASA Interagency Implementation and Advanced Concepts Team (IMPACT) Project. With a Ph.D. in meteorology and a primary research focus on exploring the variability of essential climate variables of Earth atmosphere, ocean, and cryosphere, she has worked with various types of Earth observations and derived data products. She has first-hand experience of the challenges in finding and obtaining data quality information, which led her to find ways to systematically evaluate data quality as well as document and share quality information. Dr. Peng is a strong advocate of promoting scientific data stewardship and open science. She has volunteered for organizations that strive to minimize the barrier to data and information sharing, such as the Earth System Science Data (ESSD) Journal, the World Meteorological Organization (WMO), and the Earth Science Information Partners (ESIP). Dr. Peng is a leading author of several data stewardship assessment models for national and international Earth science organizations and has published a number of peer-reviewed papers on trends and variability of climate data, research data management and stewardship.
