Hi Rick, re: > I'm trying to determine the approximate date that icing products were > first sent in the NOAAPORT stream. I'm specifically looking for CIP and > FIP data. I think that the best thing to do is search the nws-changes email list archive: Unidata HomePage: http://www.unidata.ucar.edu Support http://www.unidata.ucar.edu/support Search or browse the mailing list and support archives https://www.unidata.ucar.edu/search.jsp In the section labeled: Search Unidata's Mailing List Archives set the email list to search as 'nws-changes' (select from list) and enter the CIP or NIP as the search criteria. I did this using CIP and got a number of relevant links back: http://www.unidata.ucar.edu/mailing_lists/archives/nws-changes/2006-August/004388.html http://www.unidata.ucar.edu/mailing_lists/archives/nws-changes/2006-July/004349.html http://www.unidata.ucar.edu/mailing_lists/archives/nws-changes/2004-June/003478.html http://www.unidata.ucar.edu/mailing_lists/archives/nws-changes/2002-February/002388.html ... The last URL suggests that he CIP product was added to NOAAPort in late March, 2002: ... DRGAA609 EFFECTIVE MARCH 27 2002 AT 1300 UTC THE CURRENT ICING POTENTIAL /CIP/ GRIB PRODUCT WILL ADDED TO THE AWIPS/NOAAPORT DATASTREAM. ... The NIP search is left as an exercise :-) > Thanks in advance No worries.
