Brief Bio
Erin Delaria has worked at NASA Goddard Space Flight Center (GSFC) since 2021 and is a member of the 614 In Situ Observations Laboratory, which supports NASA Earth Science objectives through airborne measurements of atmospheric trace gases such as nitrogen dioxide (NO₂), formaldehyde (HCHO), and ozone. She has participated in several airborne field campaigns, including BlueFlux, AEROMMA, DCOTSS, ACCLIP, and ASIA-AQ, and is a regular participant in the NASA Student Airborne Research Program (SARP).
Her research uses observations from multiple airborne platforms to better understand atmospheric chemistry and air quality. Erin applies chemical box modeling to interpret in situ measurements and investigate the processes that control trace gas chemistry in the atmosphere. She also uses airborne eddy covariance techniques to measure surface–atmosphere exchange over urban, agricultural, forested, and wetland landscapes, helping to connect fluxes to air quality and the carbon cycle. Erin contributes to laboratory efforts to maintain, develop, and improve instrumentation for measuring NO₂, HCHO, and ozone.
Erin earned a B.A. in Chemistry from Pomona College and a Ph.D. in Chemistry from the University of California, Berkeley.
Current Projects
FarmFlux
Atmospheres
NASA FarmFlux is a NASA Earth Venture Suborbital (EVS-4) airborne field campaign designed to improve understanding of the interactions between U.S. agriculture and the atmosphere. The mission will deploy both a large research aircraft and a smaller aircraft to quantify emissions from major crop systems and animal feeding operations, respectively. Role: Instrument PI for NO2 on the small research aircraft and leadership role on the flux science team for the large aircraft.

BlueFlux
Carbon Cycle
NASA BlueFlux is an interdisciplinary NASA Carbon Monitoring System (CMS) project focused on quantifying carbon dioxide (CO₂) uptake and methane (CH₄) emissions from coastal blue carbon ecosystems, including mangrove forests, marshes, and wetlands in South Florida. The project combines airborne, ground-based, and satellite observations to measure greenhouse gas fluxes across multiple spatial scales and evaluate how disturbances such as hurricanes, sea-level rise, and ecosystem restoration influence coastal carbon budgets. BlueFlux provides critical data to improve greenhouse gas inventories and assess the role of coastal ecosystems in climate mitigation. Role: PI
In situ airborne measurements of formaldehyde, nitrogen dioxide and ozone
Atmospheres
This project involves maintaining and flying the GSFC In Situ Airborne Formaldehyde instrument (ISAF), Compact Airborne Formaldehyde Experiment (CAFE), Compact Airborne Nitrogen diOxide Experiment (CANOE), and Rapid Ozone Experiment (ROZE) in NASA and non-NASA aircraft campaigns. Recent campaigns include BlueFlux, ASIA-AQ, SARP, ACCLIP and DCOTSS. The instruments have flown on the NASA DC8 and ER2, NOAA P3, NCAR GV, and Dynamic Aviation A200. Funded by Tropospheric Chemistry and Upper Atmospheric Research Programs. Role: Co-I
