ORACLES - P-3 Orion 08/31/17 Science Report

Mission: 
ORACLES
Mission Summary: 

The goal today was to resample the plume that was sampled yesterday (30 August) at 3.5km and 3.0km between 4S and 10S along 5E (Routine Track). HISPLIT forward trajectories were used to determine the latitude, longitude and altitude of these same airmasses on 31 August.
The HSRL was not working (cooler problem) so the flight plan was adjusted to exclude a high-altitude survey leg; instead the focus was fully on in-situ sampling.
 
On Aug 30 the P3 sampled the plume on its south-bound leg along 5E between 4S and 10S at 3.5km altitude. Today, we resampled this plume approx. 25 hours later, also headed south-bound, between 2.8 and 3.1km altitude.
 
On Aug 30 the P3 then sampled the plume on its north-bound along 5E between 8S and 3S at 3.0km altitude. Today we resampled this plume approx. 25.5 hours later, also headed north-bound, between 2.7 and 3.1km altitude. While the plume was projected to be lower than this, we found that at 2.6km we had dropped out of the bottom of the plume. In the middle of this north-bound leg we descended to just above cloud, then in-cloud, in order to get remote sensing measurements and cloud measurements in coordination with the A-Train overpass. At the northern end of the in-situ plume leg (corresponding to airmasses sampled at 3-5S on 30 Aug) we did a series of stacked legs at 2.7km, 2.9km and 3.0km to check for vertical variations in aerosol properties.
