NOAA Heritage Oral History Project


NOAA Heritage Oral History Project aims to document the history and legacy of NOAA through compelling interviews with its leaders. These firsthand accounts provide an invaluable resource that preserves NOAA's significant contributions to environmental research and management, fostering a deeper understanding of NOAA's vital role in shaping our understanding of the Earth's oceans and atmosphere.

Date of Interview

Molly Graham

Principal Investigator

Since 1980, Tom Wrublewski has been a physical scientist with the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA) National Environmental Satellite, Data and Information Service (NESDIS). In this post, he initially monitored the operation of instruments onboard the Geostationary Operational Environmental Satellites (GOES) and Polar-orbiting Operational Environmental Satellites (POES) to assure they were properly calibrated and functioning adequately. In January 2020, he retired from the NOAA Joint Polar Satellite System (JPSS) Office at NASA Goddard Space Flight Center.

At Goddard, he worked on the instruments for the GOES-G&H satellites, the refurbishment and launch of NOAA-D, the incorporation of US Air Force Space Test Program instruments on NOAA-I&J; and the acquisition of the POES NOAA-HIJ; K L M; and N and N Prime satellites, instruments, and launch services. He  worked on the GOES Solar X-Ray Imager acquisition followed by the GOES-NOP spacecraft acquisitions. Since 2002, Wrublewski offered his technical and educational expertise to the GOES/POES education and public outreach efforts by working with NASA’s Jet Propulsion Laboratory on Space Place and, a weather-related Web site geared towards middle school students and teachers. He prepared educational posters, and newspaper and educator journal articles about GOES/POES-related science and technology. In April 2007, his responsibilities were expanded to include the NESDIS acting acquisition management lead for the NOAA-N Prime satellite and the MetOp-B&C NOAA provided instruments. Following the successful launches of GOES-NOP and NOAA-N Prime during the 2006-2010 era, Tom transitioned to helping with the Deep Space Climate Observatory (DSCOVR) project formulation and specifications for its launch services with the USAF. 

In 2011 Tom joined the NOAA JPSS Technical Division where he assisted with getting the JPSS-1 satellite and its five government furnished instruments on contract.  In 2014 and 2015 Tom worked on gathering requirements and studies for the JPSS-2 satellite and served on the Source Evaluation Board for proposal evaluations.  This is a firm fixed-price order for the purchase of the JPSS-2 spacecraft with options to purchase the JPSS-3 and JPSS-4 spacecraft.

In his spare time, Wrublewski enjoys gardening, with over a thousand various daffodils and narcissus blooming in the springtime at his residence and tending to hundreds of daylilies during the summer and fall.

Scope and Content Note

Thomas Wrublewski provides insights into his personal background and career. He describes how he attended the University of Maryland - Baltimore, before joining the National Oceanic and Atmospheric Administration (NOAA) full-time where his first position was as a physical scientist in the calibration group, where he worked on polar-orbiting and geostationary satellites. Wrublewski recalls the early days of satellite technology when computers were custom-built and data was recorded on tapes. He also discusses the challenges and interesting aspects of working with satellite instruments, such as the high data rates and anomalies that needed to be analyzed. Wrublewski goes on to describe the impact of volcanic ash on satellites and its measurement capabilities. The visible instruments, AVHRR and VIIRS, can detect volcanic ash clouds. Additionally, the OMPS instrument can detect sulfur dioxide and other trace gasses associated with volcanic activity. 

The interview then moves on to discussing the launch and operation of satellites. Wrublewski explains that earlier satellites were launched using intercontinental ballistic missiles and had an apogee kick motor to circularize their orbits. He also shares anecdotes about rockets and satellites, including the Atlas E rocket, the NOAA-D satelite, the NPOESS (National Polar-orbiting Operational Environmental Satellite System). Wrublewski mentions the impact of budget cuts on satellite projects and the importance of maintaining reliability and availability of satellite systems. He also touches on the evolution of satellite technology, including the TIROS (Television Infrared Observation Satellite) series, DMSP (Defense Meteorological Satellite Program), and the importance of polar-orbiting satellites in providing global coverage and data for weather modeling.
