The Auxiliary datasets are datasets in ICOADS standard formats that will be included in the formal ICOADS database in the future. They are offered here, so that users have access to the data as soon as possible and don't need to wait for a formal ICOADS release update. These data have been quality checked for basic parameter ranges, but have not been cross checked for matching duplicates in ICOADS.

ACCESS NOTE: These auxiliary data are also available through an interface that submits a request for subsetting of the ICOADS Observation Archive.
