Warn about Yahoo down time

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. It is provided for general use under an open source License.

Please post question or problems on the Cloudy discussion board. Updates to Cloudy will be announced on that board.

As of Dec 1 the discussion board cannot be reached via the web interface. Likely email to the group doesn't work either. It is not known how long this situation will last.

C17.00, is released. This paper discusses what is new. Follow the StepByStep instructions for downloading and installing the code, or go straight to the DownloadLinks page to obtain it. NewC17 explains improvements and changes.

The next Cloudy workshop will be at the National Astronomical Research Institute of Thailand (NARIT), in Chiang Mai, Thailand, May 14-25, 2018. The workshop will be patterned after the very successful program at INAOE, Tonantzintla, Mexico, lasting two weeks with three speakers. For more details visit the workshop website at NARIT.

Getting started with Cloudy

The VideoPage has several videos showing how to build and run Cloudy.

StepByStep instructions for downloading and installing the release version, and running the code on various platforms.

Or you can go straight to the DownloadLinks page.

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.

The RevisionHistory pages list changes and new features in past, current and the next versions.

Frequently asked questions are on the FaqPage

More information about Cloudy

Old versions of Cloudy are on the CloudyOld page

The DownloadLinks page gives links to download the current version of the code, and trial versions if they exist.

Acknowledgments for help with Cloudy are on the AcknowledgmentsPage

ContributedMaterial - codes and spectra contributed by others.

A list of typos in AGN3 is posted here. (updated 2016 August)

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.
