Welcome to DART, the Data Assimilation Research Testbed. DART is an open-source, freely available community facility for ensemble data assimilation (DA).

The DART documentation is available online.

There is a mailing list where we summarize updates to the DART repository and notify users about recent bug fixes. It is not generally used for discussion so it's a low-traffic list. To subscribe to the list, click on Dart-users.

DART is available through GitHub. To download the latest version of DART:

git clone https://github.com/NCAR/DART.git
