Add-on Data for the ICOADS Value-Added Database (IVAD)

This dataset contains original community-based contributions that are added onto ICOADS records as part of the ICOADS Value-added Database project. These contributions were first added to ICOADS beginning with Release 3.0.0 and are realized as separate attachments in the IMMA format, e.g. reanalysis feed back and QC, bias adjustment for wind and SST, and etc. In general, these data are NOT recommended for the average data user.
