Space-time paired simulation-observation records

Files uploaded to ScienceHub pair the model results in space and time to observations of NCAR NOy, NO, NO2 and O3, UC Berkeley NO2, peroxy nitrates, alkyl nitrates, and nitric acid, made aboard the NASA P3B aircraft during the DISCOVER-AQ, Maryland, 2011. Data are paired as follows: Model predictions are paired with aircraft measurements in space where aircraft latitude, longitude, altitude were matched to nearest grid cell center and model layer center height. Fifteen second averages of measurements were matched to modeled estimates in time to the nearest hour.

Observational data is also archived at the NASA LaRC Atmospheric Sciences Data Center (https://www-air.larc.nasa.gov/data.htm).

This dataset is associated with the following publication: Simon, H., K. Baker, L. Valin, J. Crawford, S. Puesede, J. Kelly, K. Foley, R. Cohen, B. Timin, A. Weinheimer, N. Possiel, C. Owen, C. Misenis, G. Diskin, A. Fried, and B. Henderson. Characterizing CO and NOy Sources and Relative Ambient Ratios in the Baltimore Area Using Ambient Measurements and Source Attribution Modeling.
