Carbon Sources and Sinks Over North America

Gross Primary Productivity

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

Modeled estimates of biogenic CO2 exchanges between land and atmosphere across portions of North America are available.

Reanalyzed Atmospheric Particulate Iodine Concentrations

Reanalysis of initial High-Resolution Aerosol Mass Spectrometer measurements of global oceanic coverage of particulate iodine are now available.

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).
