POST: CIRPAS Twin Otter 1-hz CAS Drop Size Spectra

Summary

This data set includes airborne measurements obtained from the CIRPAS Twin Otter aircraft during the "Physics of Stratocumulus Tops" (POST) project off the west coast of Monterey, CA. This data set contains 1 hertz (1 sps) size distributions of aerosol and cloud particles measured by the forward (F)- scatter (CAS) section of the CAPS probe. The files are the final data in columnar ASCII format.
