The Dependence of Direct Aerosol Radiative Effects on the Underlying Albedo and Aerosol Properties: Results from the 2016 and 2017 ORACLES Field Campaigns

We will present (a) the spectral aerosol properties of single scattering albedo (SSA) and asymmetry parameter (g), (b) the direct aerosol radiative effect (DARE) as a function of the underlying albedo, and (c) aerosol, gas, and total absorption and heating rates from the 2016 and 2017 deployments of the NASA ORACLES experiment (ObseRvations of CLouds above Aerosols and their intEractionS). Observations by the Solar Spectral Flux Radiometer (SSFR), the Spectrometer for Sky-Scanning Sun-Tracking Atmospheric Research (4STAR), and the High Spectral Resolution Lidar (HSRL-2,) are used in conjunction to retrieve the spectral SSA and g, which are then used to determine the aerosol absorption and radiative effect. Based on a subset of flight data taken from both deployments, we determine parameterizations for DARE and related parameters on the aerosol properties.
