According to Song, this finding highlights the need to improve how organic aerosols are currently represented in climate models.
Because small - scale climate features, such as clouds and atmospheric aerosol particles, have a large impact on global climate, it's important to improve the methods used to represent those climate features in the models.
Stage 2 uses these measurements to develop and evaluate models that represent these individual aerosol and cloud processes and properties.
«Until recently, aerosol processes were under - represented in global climate models because of disconnects between various research programs,» explained Ghan.
«Inorganic aerosols, like sulfates, nitrates, and ammonium, are well - represented in climate models.
To find out if including the shielding of PAHs by viscous aerosols would improve global atmosphere models, the scientists used laboratory experiments to develop a new way of representing PAHs in a global model.
Differences in how a model represents space and time scales, emission rates, meteorology, gas - phase chemistry, and other aerosol processes all affect model predictions.
He chose a figure which represented model simulations of temperature responses only to greenhouse gas changes, which neglects for example the temperature response to the cooling effects of aerosols.
The climate models should use aerosol offsets which represent current best estimates, if they want people to take the AR5 declarations of model accuracy seriously.
As far as re-calibrating a model for various initial conditions or shoving more aerosol forcing down its troat, it really comes down to which approach better represents reality.
The verification comparison with ACCMIP doesn't really work because the models included in that project represent only a subset which are the most fully - featured for aerosol modelling, and therefore generally produce the most negative aerosol forcings.

Nonetheless our understanding of aerosol - cloud interactions is incomplete, and what is well - understood, is incompletely represented in large - scale models.
Surely after decades of satellite measurements, countless field experiments, and numerous finescale modeling studies that have repeatedly highlighted basic deficiencies in the ability of comprehensive climate models to represent processes contributing to atmospheric aerosol forcing, it is time to give up on the fantasy that somehow their output can be accepted at face value.»
Current global climate models suggest that the water vapor feedback to global warming due to carbon dioxide increases is weak but these models do not fully resolve the tropopause or the cold point, nor do they completely represent the QBO [Quasi Biennial Oscillation], deep convective transport and its linkages to SSTs, or the impact of aerosol heating on water input to the stratosphere.
However, this is all somewhat academic because the fingerprint - based detection and attribution results in AR5 show that models used by Shindell to estimate his enhanced response factor E poorly represent the real world response to aerosol, ozone and land use forcings.
-- Atmospheric models have improved and many now represent all aerosol components of significance.
