Here, this study examines the application of the daytime-mean and insolation-weighted-mean solar zenith angles to calculate the diurnally-averaged aerosol direct radiative effect (DRE), DRE_DA, for observed clear-sky conditions at the Atmospheric Radiation Measurement Program (ARM) Southern Great Plains (SGP) and Tropical Western Pacific (TWP) sites. As compared with the reference calculation, the DRE_DA are too strong (i.e., more negative) using daytime-mean solar zenith angles (DTMSZA) and are too weak (i.e., less negative) using insolation-weighted-mean solar zenith angles (IWMSZA). The biases in the DRE_DA for DTMSZA (IWMSZA) are about -0.8 (0.7) W m^-2 at the TOA and about -1.5 (0.9) W m^-2 at the surface. Noting the mean TOA DRE_DA of -2.85 W m^-2 and the surface DRE_DA of -7.09 W m^-2 at SGP, the relative biases for DTMSZA (IWMSZA) are 26% (-24%) for the TOA DRE_DA, and 17% (-11%) for the surface DRE_DA. At TWP, the mean TOA DRE_DA is -2.81 W m^-2 and the surface DRE_DAis -11.84 W m^-2 which corresponds to relative biases for DTMSZA (IWMSZA) of 29% (-27%) for the TOA DRE_DA and 15% (-9%) for the surface DRE_DA. By introducing an adjusted insolation-weighted-mean solar zenith angle, the mean biases in the DRE_DA at the TOA becomes -0.09 W m^-2and the biases in the DRE_DAat the surface are about -0.41 W m^-2. Also presented are the effects of using the mean solar zenith angles on the shortwave (SW) upward fluxes at the TOA and SW downward fluxes at the surface in both clear-sky and pristine-clear-sky (i.e., gases only) conditions.
