ATom Compiles Flask Data from 2009 to 2018

Map and graph of airborne flask sample locations.

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.

Soluble Acidic Gases and Aerosols (SAGA) Instrument Data

Instrument: Soluble Acidic Gases and Aerosols (SAGA).

The SAGA installation onboard the DC-8 - AFRC aircraft.

Soluble ion measurements are available from the Atmospheric Tomography Mission (ATom).

Atmospheric Concentrations from the QCLS Instruments

Image of the the Harvard QCLS Instrument

The Harvard QCLS (DUAL and CO2) instrument package contains 2 separate optical assemblies and calibration systems, and a common data system and power supply.

The Harvard Quantum Cascade Laser System (QCLS) instrument data is now available from the Atmospheric Tomography Mission (ATom).

New Instrument Data From ATom

Image of the UCATS system.

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).

Model-Derived CO2 Biogenic Fluxes

Gross Primary Productivity

Mean gross primary productivity (GPP) for the conterminous US and North America in grams of carbon per unit area per month.

Carbon fluxes and uncertainties are available from the Atmospheric Carbon and Transport - America (ACT-America) project.
