Large Programs

Large Programs are designed to address strategic scientific issues that will lead to a major advance or breakthrough in the field. The Large Program proposal teams produce high level data products and documentation which are made available to the scientific community within one year after the final delivery of calibrated data. Large Programs are distinguished from Regular Proposals in the following ways:

  • They are programs with an estimated execution time of greater than 50 hours on the 12-m Array (with or without accompanying ACA time) or 150 hours on the ACA in stand-alone mode.
  • They are designed to be coherent science projects that are not reproducible by a combination of Regular Proposals. 
  • Investigators must deliver high level data products and relevant documentation in a manner consistent with the management plan of their proposal.


The following table contains the full list of ALMA Large Programs, as well as links to the data products delivered by the teams. The Programs are listed first by Science Category, then by Cycle number:
