Horizontal (left) and vertical (right) distribution of airborne flask sample locations identified as being of stratospheric origin. Thin dashed black lines on the map illustrate the flight tracks of all 9 campaigns of the 3 airborne projects. Symbols indicate the campaigns during which the stratospheric samples were collected, and colors show the potential temperature at which the sample was taken.
A new dataset from the Atmospheric Tomography Mission compiles measurements of mean age of air.
The UCATS system is three different instruments in one enclosure: a two-channel chromatograph with electron capture detectors (one measures N2O and SF6, the other measures CH4, H2 and CO), a tunable diode laser instrument for H2O, and a dual-beam O3 photometer.
A new dataset was collected using the Unmanned Aircraft Systems (UAS) Chromatograph for Atmospheric Trace Species (UCATS).
