Postcard from the Field: High Altitude Test Flights Begin for NOAA CSL's SABRE Mission in Houston, Texas. 17 February 2022

Test flights for the Stratospheric Aerosol processes, Budget and Radiative Effects (SABRE) mission started this week in Houston, TX. Scientists from NOAA's Chemical Sciences Laboratory and CIRES, along with NASA and university partners, have been at Ellington Field for the past two weeks to test new atmospheric instrumentation on NASA's high-altitude WB-57 research aircraft. The test flights allow the scientists to check the performance of research instruments, many of which are newly developed or have never been flown at extremely high altitudes.
NOAA CSL's SABRE mission will study the chemistry and composition of the upper troposphere and lower stratosphere up to altitudes of 60,000 ft. The instrumentation on-board will capture real-time measurements of trace gases such as ozone and chlorine compounds, as well as the composition, microphysics, and radiative properties of aerosols. SABRE measurements will ultimately enable more accurate quantification of the direct and indirect climate impacts from variations in stratospheric aerosols and gases in the present-day atmosphere and provide a foundation for estimating changes in aerosol radiative forcing under future climate scenarios.

SABRE is a NOAA Earth's Radiation Budget (ERB) Initiative project.
