17 Goals of the 2030 Sustainable Development Goals of the United Nations.
The communication tower at the Wessington, South Dakota site. This site was instrumented from January of 2017 to September of 2019.
Level 1 atmospheric greenhouse gas concentrations are available for towers across the central and eastern USA.
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.
Particulate iodine measured along flight paths in ATom1 and ATom2. Image by J.L. Jimenez
Reanalysis of initial High-Resolution Aerosol Mass Spectrometer measurements of global oceanic coverage of particulate iodine are now available.
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 SAGA installation onboard the DC-8 - AFRC aircraft.
Soluble ion measurements are available from the Atmospheric Tomography Mission (ATom).
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 QCLS instrument package was used to measure atmospheric concentrations.
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).
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.
Measurements of atmospheric carbon dioxide concentration from flasks collected by the Medusa system during ATom-4 flights in 2018.
NASA's Atmospheric Tomography (ATom) campaign collected whole air samples and measurements of formaldehyde during round-the-world flights.
