ARCTAS Flight 20

DIAL Aerosol and Ozone Distributions


 

Flight 20 / Cold Lake Local #4 / July 5, 2008

DC8 flight track (UT) | Entire Flight |

Note:

1.      DIAL measures ozone densities, the molecular densities from the RAQMS model (kindly provided by B. Pierce of NOAA) have been used to calculate mixing ratios.

2.      The DIAL ozone images contain insitu ozone from the NCAR NOxyO3 4-channel chemiluminescence instrument (PI: A. Weinheimer) at DC-8 flight altitudes.

3.      Scattering ratio normalizations have used molecular densities from the RAQMS model (provided by B. Pierce of NOAA).
