Direct Aerosol Forcing in the Infrared at the SGP Site

As aerosols deliquesce, they become more liquid, and thus we performed a series of calculations to investigate the response of the infrared atmospheric window to small changes in the liquid water path (LWP). For these calculations, we used the Line-By-Line Radiative Transfer Model-discrete ordinate radiative transfer (LBLRTM-DISORT) forward model (Turner 2004) to compute the downwelling radiance from 8 to 13 µm for a range of LWP. We assumed an effective radius of 2 µm for these calculations since the droplets are not fully activated in haze conditions, and distributed the droplets in the lowest 200 m of the atmosphere. The results are shown in Figure 1. These results demonstrate that very small LWPs have an appreciable effect on the infrared window radiance, as LWPs of 0.5 and 1.0 g/m 2 increase the downwelling longwave surface flux by approximately 10 and 20 W/m 2 , respectively. To put this into perspective, the uncertainty in the microwave radiometers LWP is about 25 g/m 2 (Westwater et al. 2001).
