Hello Fred,
     
Beginning Wednesday April 21, we at SSEC and many of our users began noting some
changes in the MRF/AVN and RUC products on the NOAAPORT broadcast. Due to the 
vagueness of the above administrative message, I am unsure if the changes we're 
seeing are related.
     
The problem we are seeing is in the way the MRF/AVN and RUC products are 
categorized in the Category and Sub-category of the Communications Control Block
(CCB) in the NOAAPORT protocol. It appears as though the category and
 subcategory
of these GRIB products have changed from category 2 subcategory 1 to category 2 
subcategory 0. Category 2 subcategory 0 is defined in table 7-2 of the 'Standard
Telecommunication Procedures for Weather Data Exchange' as a 'WMO ASCII data
 code
form'. The SSEC NOAAport receiver uses the category/subcategory parameters to 
split the feed into a binary stream and a text stream. The changes caused us 
great problems and until we located the problem, prevented over 100 universities
from receiving this model data.
     
We are also seeing this problem with a number of additional products. These 
products contain binary data, but are flagged as ASCII text in the CCB 
category/subcategory.
     
The CCB category/subcategory is a documented piece of the NOAAPORT protocol. 
Developers of NOAAPORT receiving stations rely on this documentation and their 
represented data values when developing software. It is important that these 
values be correct. In our case, it is very important that only ASCII text data
 be
defined as category/subcategory 1/10 or 2/0. Category/sub-category 2/1
 represents
WMO GRIB code forms. Why aren't all GRIB products categorized by this category 
and subcategory in the NOAAPORT broadcast?
     
I was hoping you could look into the cause of these changes and correct the 
values placed in the category/subcategory in the CCB.
     
Below are the WMO headers of all products in addition to the RUC,AVN, and MRF 
that we must treat special because they contain binary data bytes but are 
categorized as 2/0 WMO ASCII.
     
Thank you for looking into this, your help is greatly appreciated.
     
-Chad

     Hi Chad,
     
     Again, Thank you for bringing this to our attention.  The changes we 
     made here did result in the CCB changes you noticed.  We have backed 
     off these changes this morning to restore the CCB to the state it was 
     in prior to last Wednesday.
     
     Cheers, Fred
