Abstract

Smoke particles from biomass burning can generate forcing of climate by modifying cloud microphysics and reflectance of sunlight. Cloud modification, critical to an understanding of climate change, is uncertain and variable. Satellite data over the Amazon Basin and Cerrado were analyzed for cloud reflectance and droplet size and for smoke concentration. Smoke increased cloud reflectance from 0.35 to 0.45, while reducing droplet size from 14 to 9 micrometers. The regional variability of the smoke effect was correlated to the availability of water vapor. During the 3 months of biomass burning in the dry season, the smoke-cloud forcing of climate was only −2 watts per square meter in this region, much smaller than what can be inferred from model predictions.

  32. Apparent temperature is derived from the radiance at 11 μm measured by the satellite T 11 . It is lower by a few degrees kelvin than the actual temperature because it is derived assuming that the cloud top is a black body and ignoring effects of the atmosphere above the cloud.
  33. The 0.64-μm channel was corrected for sensor degradation [Y. J. Kaufman and B. N. Holben Int. J. Remote Sens. 14 21 (1993) (10.1080/01431169308904320)
  34. N. Che and J. C. Price Remote Sens. Environ. 41 19 (1992)]. The on-board black bodies that emit thermal radiation in fixed temperatures are used to calibrate the 3.7- and 11-μm channels. The cloud reflectance at 3.7 μm ρ c4 was derived by subtracting the emissive part at 3.7 μm computed with T 11 and correcting for attenuation and emission by water vapor derived from radiosonde data. Profiles of water vapor measured from radiosonde were obtained from the National Center for Atmospheric Research (obtained from D. Joseph personal communication). In the analysis the emissivity was assumed to be 1.0 at 11 μm and 1 − ρ c4 at 3.75 μm because clouds selected by Eq. 1 are not transparent in these infrared channels (13). A sensitivity and validation study (20) indicates accuracy of the cloud droplet size for a similar method of ±2 μm and a precision that is better than that. τ s is derived from the satellite-measured radiance over cloud-free shadow-free pixels with dark vegetation cover (13 34) by means of a smoke optical model (14). Similar procedures applied to satellite data resulted in an uncertainty of Δτ s ± 0.1 (35). For high optical thickness an error of 20 to 30% is expected from uncertainty in the smoke-scattering phase function and single-scattering albedo.

  47. The value determined by Penner et al. (2) of the global average indirect forcing by smoke could be an overestimate because (i) the study assumes a global homogeneous spatial distribution of the smoke aerosol in the presence of nonlinearity of the smoke effect; (ii) it neglects the presently observed low forcing for low availability of precipitable water vapor; and (iii) it neglects the production of smoke in the dry season with low cloud fraction.
