Three tours into the IFA were carried out. On the first, coordinated flights with the P3s and the Electra were conducted. During the third period the C130 was the only aircraft operating. A series of shallower profiles from 30-1500 m were done at intervals throughout the flight. The level runs were about 150 km long.
N represents the number of the profile within the flight.
Measured air temperatures have been reduced by 0.55K based on an analysis of heat flux data. Measured dewpoints have been increased by 0.75K based on a comparison between humidity measurements on low-level runs and near simultaneous measurements on the Franklin. The vertical wind component has a non-zero mean which should be removed if the data are to be used to calculate fluxes. Shortwave fluxes are measured by Eppley pyranometers.
