For accessing data from the GTS, the workflow is reversed. NDC’s will harvest the data from the GTS using their connection to the WIS, decode the BUFR messages, save the data in a consumable format and load the data into ERDDAP. It is also possible to push the data into ERDDAP directly as part of the decoding process, thereby skipping the need to create intermediate files. Once in ERDDAP, data consumers are free to access and use the data in a variety of formats, ensuring that they will be able to use the data of the clients they are most familiar with, without being burdened by the cumbersome process of reformatting BUFR data. It is worth noting that the ERDDAP data platform also supports federation, thereby creating easy access to distributed datasets as well. This capability ensures that data consumers who may not have a direct connection to the WIS would still be able to access and use the near-real-time data.
