New Merged Product Integrates G-1 Flight Data

 
Published: 26 November 2024
A map of a flight path near Córdoba, Argentina, shows variations in concentration from an ultrafine condensation particle counter (1/cm^3). The legend goes to above 8,000.
Aerosol concentration data from the G-1 ultrafine condensation particle counter are shown for an approximately three-hour flight on December 8, 2018, near Córdoba, Argentina, during the CACTI campaign. Image is from Krista Gaustad, Pacific Northwest National Laboratory.

From 2010 until its final science mission in 2018, the Gulfstream-159 (G-1) aircraft served as the Atmospheric Radiation Measurement (ARM) user facility’s main airborne research laboratory. The new ARM Aerial Facility (AAF) Merged value-added product (AAFMERGED VAP) for historical AAF G-1 campaigns has been developed to provide users with a set of frequently used G-1 measurements (e.g., atmospheric parameters, aerosol and trace gas concentrations) in a single netCDF file. This merged product allows users to quickly access the key measurements from nearly two dozen AAF products.

AAFMERGED evaluation data are now available for G-1 flights during the following ARM campaigns and date ranges:

More information about AAFMERGED is available on the VAP web page.

Scientists can use the new data now. Additional AAFMERGED data from the final six years of G-1 operations (2013 to 2018) will be released for the following campaigns:

Access the available AAFMERGED data in the ARM Data Center. (To download the data, first create an ARM account.)

To share your experience—such as how you use the data and how well they work for you—or to ask a question, contact AAF Science Lead Fan Mei.
