POSIDON - WB-57 #927 10/26/16 Science Report

Sample ice clouds and dehydration in the low temperature region to the southwest of Guam, and explore SO2 and O3 distributions in the TTL.

POSIDON - WB-57 #927 10/25/16 Science Report

This flight provided measurements of trace gases and ice crystal microphysical properties in anvil cirrus after the convection had subsided and in cold cirrus near the tropopause. Enhanced ozone concentrations in the uppermost troposphere were also measured on this flight. 

POSIDON - WB-57 #927 10/21/16 Science Report

This flight is designed to explore the chemical composition in the tropical tropopause layer in the region south of Guam

POSIDON - WB-57 #927 10/19/16 Science Report

This flight provided additional sampling of TTL trace gases and cirrus in air perturbed by typhoon Haima as well as water vapor concentration across a horizontal temperature gradient. 

POSIDON - WB-57 #927 10/18/16 Science Report

POSIDON - WB-57 #927 10/15/16 Science Report

This flight provided an ideal opportunity to sample gases and clouds detrained from a tropical cyclone. The WB-57 profiled through the TTL throughout the flight, sampling cirrus just downstream of convection extending well above 50 kft and through thin cirrus up to the tropopause. Instruments performed well.
