Description

As part of the FAst-physics System TEstbed and Research (FASTER) project, RACORO aircraft data are being used to construct case studies to assess and improve models of continental boundary-layer clouds (stratus, stratocumulus, and cumulus). RACORO was a first-of-a-kind, extended-term cloud aircraft campaign that was conducted by the Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF) to obtain an in situ statistical characterization of boundary-layer clouds. The field campaign operated for five months over the ARM Southern Great Plains (SGP) site, from 22 January to 30 June 2009, collecting 260 hours of data during 59 research flights over a range of conditions associated with the winter-to-summer seasonal transition. A comprehensive payload aboard the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) Twin Otter aircraft measured cloud microphysics, solar and thermal radiation, aerosol properties, and atmospheric state parameters. Proximity to the SGP's extensive complement of surface measurements provides additional data that support development of these case studies for use by FASTER and the Atmospheric System Research community.
