As the program evolved, temperature sensors were added to the drifters.  Nearby ice concentration from SSMI satellites had also been added to some datastreams.  Please visit the source ascii files or the netcdf files in the erddap "filesystem" for the maximum amount of meta-data information as not all details are broadcast to the collection.</att>
