Mary Anderberg — Scientist
M.S. Physics, University of Denver
B.S. Physics, Auburn University
Mary performs solar radiometric data quality analysis for the U.S. Department of Energy's Atmospheric Radiation Measurement program and provides programming support for the resource integration section. She also contributed to the National Solar Radiation Database update. In addition, Mary is the Web administrator of the Renewable Resource Data Center, for which she provides UNIX, C, Perl, and HTML support.
Afshín Andreas — Senior Scientist
B.S. Engineering Physics, Colorado School of Mines
Afshín is a scientist with over 15 years of research experience in spectoradiometery, solar radiation measurements, and computer programming. Afshin performs calibrations of spectroradiometers in the Optical Metrology Laboratory using National Institute of Standards and Technology traceable lamp standards. Afshín operates spectroradiometers to perform measurements of natural solar radiation and artificial light sources, such as solar simulators, for both NREL and industry. He helps maintain the baseline monitoring of solar and meteorological measurements at the Solar Radiation Research Laboratory. His co-development of the Radiometer Calibration and Characterization software enables improved Broadband Outdoor Radiometer Calibration performance. He also developed and maintains the Measurement and Instrumentation Data Center website and provides solar radiation resource data to the Renewable Resource Data Center. Afshín has programming skills in C/C++, Perl, HTML, LabWindows/CVI, and Campbell Scientific dataloggers. He also provides application software development for the U.S. Department of Energy's Atmospheric Radiation Measurement program, a climate change research effort.
Mike Dooraghi — Engineer
M.A. Industrial Technology, Appalachian State University
B.A. Mathematics, Computer Science, Appalachian State University
Mike is an engineer who has extensive background with instrumentation for wind and solar resource assessment systems as well as loads and power measurements for wind turbines. He manages the Electronics Laboratory at the Solar Radiation Research Laboratory and provides research support for the Measurement and Instrumentation Team and other NREL staff. He installs rotating shadowband radiometers, pyranometers, and pyrheliometers along with other meteorological sensors, and he configures instrumentation and communications devices for remote deployment of solar monitoring systems for the SOLRMAP program and for PV variability studies.
Aron Habte — Scientist
M.S. Water Resource Management, University of Nevada, Las Vegas
B.S. Soil and Water Conservation, University of Asmara
Aron joined NREL in 2010. He currently leads tasks on the update of the National Solar Radiation Database (NSRDB), satellite model validation, and the American Society for Testing and Materials (ASTM) standards committee. He is a co-chair for two ASTM International standards subcommittees on radiometry and statistics. Aron analyzes and interprets terrestrial solar radiation and satellite data. He is assisting the NREL Optical Metrology Laboratory in fulfilling the ISO-17025 accreditation process for spectral irradiance measurement. He also contributed to the update of the NSRDB and Typical Meteorological Year (TMY) dataset. Prior to NREL, Aron worked in southern Nevada collecting, processing, and analyzing large volumes of high-resolution meteorological and hydrologic data.
Mark Kutchenreiter — Senior Research Technician
A.S. Air Pollution Control Engineering Technology, Pennsylvania State University
Mark joined NREL in 2010 and works at the Solar Radiation Research Laboratory (SRRL). Mark is involved in the U.S. Department of Energy's Atmospheric Radiation Measurement program and also supports additional SRRL activities including radiometer calibrations and monitoring network implementation. Prior to working at NREL, Mark worked in environmental consulting and engineering and was involved in numerous projects for private and government-related clients in support of energy development, mineral resource operations, and hazardous waste remediation. He has extensive experience in air quality, air toxics, meteorological, and hydrological monitoring, as well as monitoring method development. His previous experience also includes project management, training, auditing, and quality assurance activities.
Dr. Manajit Sengupta — Senior Scientist
Ph.D. Meteorology, Pennsylvania State University
