Flight Reports began being entered into this system as of 2012 flights. If there were flights flown under an earlier log number the flight reports are not available online.
Transited on 5E to 9.0S, then headed east to find low-cloud-fraction region. At ~7E went south to 9.5S, then headed west.
Did a radiation wall between approx. 5.5E and 7W on 9.5S. This included, in order:
Boundary layer was the most polluted we’ve seen so far in ORACLES 2018. Cloud droplet number concentrations were accordingly elevated, in both the satellite retrievals and in the P3 cloud probe measurements. Based on chemical ratios from the aerosol in-situ measurements it also appeared to be a more aged plume than on other days in ORACLES 2018.
This will make a very good case for radiative closure, given the two square spirals in different conditions, the full radiation wall, and the moderate RH in the plume (which makes it easier to estimate the ambient-RH aerosol extinction from the low-RH in-situ scattering and absorption measurements).
