P3-B O3 Quadrant Analysis

Ideally, the aircraft would act like an elevator and go straight up over a given ground site, but this is unrealistic.  The aircraft makes spirals ~5 km in diameter while measuring meteorological and air quality parameters.  These analyses show how the data are averaged and the variability of O3 amongst the given quadrants over Moody […]

OMI/Pandora O3 Column Comparison

Comparison of the Ozone Monitoring Instrument (OMI) O3 Column on board the NASA Aura spacecraft and the ground-based direct-sun spectrometer (Pandora) on board the R/V Hugh R. Sharp in the Western North Atlantic Ocean (~100 km east of Delaware, USA).  Results show that OMI is biased ~37% high.  These measurements represent the first observations from […]
