Journal ArticleDOI
The albedo of fractal stratocumulus clouds
TL;DR: In this paper, a fractal model was employed to reproduce both the probability distribution and the wavenumber spectrum of the stratocumulus liquid water path, as observed during the First ISCCP Regional Experiment (FIRE).
Journal ArticleDOI
Independent Pixel and Monte Carlo Estimates of Stratocumulus Albedo
TL;DR: In this article, Monte Carlo radiative transfer methods are employed to estimate the plane-parallel albedo bias for marine stratocumulus clouds, which arises from the assumption that cloud liquid water is uniformly distributed.
Journal ArticleDOI
Infrared radiation parameterizations in numerical climate models
TL;DR: In this paper, various approaches to parameterizing the broadband transmission functions for utilization in numerical climate models are presented; one-parameter scaling is applied to approximate a nonhomogeneous path with an equivalent homogeneous path, and the diffuse transmittances are either interpolated from precomputed tables or fit by analytical functions.
Journal ArticleDOI
Biases in Shortwave Column Absorption in the Presence of Fractal Clouds
TL;DR: In this article, the effect of cloud structure on column absorption by water vapor is investigated using an efficient Monte Carlo technique, the independent pixel approximation, and plane-parallel theory, and the spectral range between 0.9 and 1.0 mm (with strong water vapor absorption and negligible cloud liquid water absorption) is selected for a detailed study, not only of domain-averaged quantities, but also radiation fields.

TL;DR: In this paper, a large-scale regional view of the aerosol during the ACE-Asia time period was provided by the Moderate Resolution Imaging Spectroradiometer (MODIS).
