Query: Explicit cloud representation in the Atmos 1D climate model for Earth
  and rocky planet applications   1D climate models are less sophisticated than 3D global circulation models
(GCMs), however their computational time is much less expensive, allowing a
large number of runs in a short period of time to explore a wide parameter
space. Exploring parameter space is particularly important for predicting the
observable properties of exoplanets, for which few parameters are known with
certainty. Therefore, 1D climate models are still very useful tools for
planetary studies. In most of these 1D models, clouds are not physically
represented in the atmosphere, despite having a well-known, significant impact
on a planetary radiative budget. This impact is simulated by artificially
raising surface albedo, in order to reproduce the observed-averaged surface
temperature (i.e. 288 K for modern Earth) and a radiative balance at the top of
the atmosphere. This non-physical representation of clouds, causes atmospheric
longwave and shortwaves fluxes to not match observational data. Additionally,
this technique represents a parameter that is highly-tuned to modern Earth's
climate, and may not be appropriate for planets that deviate from modern
Earth's climate conditions. In this paper, we present an update to the climate
model within the Atmos 1D atmospheric modeling package with a physical
representation of clouds. We show that this physical representation of clouds
in the atmosphere allows both longwave and shortwave fluxes to match
observational data. This improvement will allow us to study the energy fluxes
for a variety of cloudy rocky planets, and increase our confidence in future
simulations of temperature profile and net energy balance.
