Welcome to the Cloudy home page!
Cloudy is a spectral synthesis code designed to simulate conditions in interstellar matter under a broad range of conditions.
Please post question or problems on the Cloudy discussion board. Updates to Cloudy will be announced on that board.
Join our team! More details on the postdoctoral fellowship are on the JobOpenings page.
Getting started with Cloudy
StepByStep instructions for downloading and installing the release version.
StellarAtmospheres in Cloudy are now very flexible. They are described on this web site rather than in Hazy.
KnownProblems are described on this page.
HotFixes are small corrections to the source that fix problems discovered after the current stable version was released.
Frequently asked questions are on the FaqPage
More information about Cloudy
The RevisionHistory pages list changes and new features in past, current and the next versions.
Old versions of Cloudy are on the CloudyOld page
The DownloadLinks page gives links to download the code
The RoadMap page outlines planned future development
Acknowledgments for help with Cloudy are on the AcknowledgmentsPage
Outside pages related to Cloudy or related physics
A list of typos in AGN3 is posted here. (updated 2007 July 19)
Morisset and Stasinska have created Cloudy 3D. This uses IDL scripts to drive Cloudy as a subprogram and create simulations of complex geometries.
ContributedMaterial - codes and spectra contributed by others.
A very old page giving miscellaneous information, including the following: people involved in its development, the code's history and style convention, computing at Cambridge in the 1970's, what the version numbers mean, the distinction between notation such as C+2 vs C III, how to call C from Fortran. Software contributed to drive Cloudy, other spectral synthesis codes, development software, atomic data, Kentucky, meetings on spectroscopy, and a collection of cloud images from across the internet.
