Formaldehyde column density measurements as a suitable pathway to estimate near-surface ozone tendencies from space.

ABSTRACT: In support of future satellite missions that aim to address the current shortcomings in measuring air quality from space, NASA's Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality (DISCOVER-AQ) field campaign was designed to enable exploration of relationships between column measurements of trace species relevant to air quality at high spatial and temporal resolution. In the DISCOVER-AQ data set, a modest correlation (r ² = 0.45) between ozone (O₃) and formaldehyde (CH₂O) column densities was observed. Further analysis revealed regional variability in the O₃-CH₂O relationship, with Maryland having a strong relationship when data were viewed temporally and Houston h
