Title: Senior Research Scientist
Technical Focus Area: Climate Science
Study Topics: Earth’s radiation budget, aerosol radiative effect
Mission/Project: CERES

About:

Dr. Wenying Su is a senior scientist at the NASA Langley Research Center in Hampton, Virginia, USA. Her research interests include Earth radiation budget, climate variability, aerosol radiative forcing, and aerosol-cloud interactions. Dr. Su is the angular distribution model working group chair for the Clouds and the Earth’s Radiant Energy System (CERES) project, and she is also a member of the Deep Space Climate Observatory (DSCOVR) science team. Dr. Su is proficient in FORTRAN and MATLAB. She has published over 50 peer-reviewed publications and was awarded the NASA exceptional achievement medal in 2016. Dr. Su has been a member of the joint Committee on Earth Observation Satellites/ Coordination Group for Meteorological Satellite (CEOS/CGSM) Working Group on Climate (WGClimate) representing NASA since 2016. She serves as one of NASA’s point of contact to register the agency’s climate data records in the CEOS Essential Climate Variable Inventory. Under her leadership, NASA contributed about 40% of the climate data records in the Inventory. She contributed to the WGClimate Gap Analysis Report and the Coordinated Action Plan. She also contributed to the Space Agency Response to Global Climate Observing System (GCOS) Implementation Plan in 2017. Dr. Su is currently co-leading the WGClimate Use Case initiative with colleagues from WMO. The main objectives of the Use Case are to demonstrate the value of Earth observation for societal benefit and decision making and to illustrate the importance of satellite observations for climate monitoring and climate service. Dr. Su is a member of the newly established Group on Earth Observations (GEO) climate change working group as a CEOS representative, coordinating the CEOS contributions to the GEO engagement with the United Nation Framework Convention on Climate Change (UNFCCC) and the IPCC, and enhancing the use of Earth observations for mitigation.

The NASA Prediction Of Worldwide Energy Resources (POWER) Project improves the accessibility and usage NASA Earth Observations (EO) supporting community research in three focus areas: 1) renewable energy development, 2) building energy efficiency, and 3) agroclimatology applications. The latest POWER version enhances its distribution systems to provide the latest NASA EO source data, be more resilient, support users more effectively, and provide data more efficiently. The update will include hourly-based source Analysis Ready Data (ARD), in addition to enhanced daily, monthly, annual, and climatology ARD. The daily time-series now spans 40 years for meteorology available from 1981 and solar-based parameters start in 1984. The hourly source data are from Clouds and the Earth's Radiant Energy System (CERES) and Global Modeling and Assimilation Office (GMAO), spanning 20 years from 2001.

The newly available hourly data will provide users the ARD needed to model the energy performance of building systems, providing information directly amenable to decision support tools introducing the industry standard EPW (EnergyPlus Weather file). One of POWER’s partners, Natural Resource Canada’s RETScreen™, will be simultaneously releasing a new version of its software, which will have integrated POWER hourly and daily ARD products. For our agroclimatology users, the ICASA (International Consortium for Agricultural Systems Applications standards) format for the crop modelers has been modernized.

POWER is releasing new user-defined analytic capabilities, including custom climatologies and climatological-based reports for parameter anomalies, ASHRAE® compatible climate design condition statistics, and building climate zones. The ARD and climate analytics will be readily accessible through POWER's integrated services suite, including the Data Access Viewer (DAV). The DAV has been improved to incorporate updated parameter groupings, new analytical capabilities, and the new data formats. Updated methodology documentation and usage tutorials, as well as application developer specific pages, allow users to access to POWER Data efficiently.
