The US Argo Data Assembly Center (DAC) processes data from all floats deployed by principal investigators and partners of the US Argo Consortium. The processing includes the decoding, quality control and distribution of the data in real-time. The data are distributed via the Global Telecommunication System and the Global Data Assembly Centers (GDACs). In addition the data are provided directly to the principal investigators and partners. The US Argo DAC also checks the integrity of the data after scientific quality control has been applied. They are then distributed to the GDACs. Various tools for monitoring and data tracking are used to ensure a high standard in timeliness of the data delivery as well as the quality of the data.
