Since I send out emails with tornado warnings and such, if I had
NOAAport and EMWIN turned on, I bet I'd get duplicate emails sent out.
Different LDM generated numbers (albeit same time stamp on the WMO
header). Otherwise, I'd do it.
If the products are first passed through an LDM system, then you
shouldn't see duplicate emails because the LDM product-queue will not
allow a data-product that has the same MD5 signature as a data-product
that is already in the product-queue to be inserted into the queue.
Of course, this requires that the data-products have the same MD5
signature and different LDM ingesters don't always compute the MD5
signature the same way.
