Subject:  Discontinue the Supplementary Data Observation (SDO) 
and Supplementary Climate Data (SCD) products.  
Effective March 3, 2012 

Effective March 3, 2012, at approximately 1500 Coordinated 
Universal Time (UTC), the NWS will discontinue the distribution 
of the SCD and SDO products. The discontinuation of the SCD/SDO 
products is a result of a 2 year evaluation of the usefulness of 
these products to distribute climate data. NWS received very few 
requests for these products and did not have a set of consistent 
users. The NWS distributes the same information through other 
products, already familiar to the public, such as Preliminary 
Climate Data (F-6), Daily Climate Report (CLI), Monthly Weather 
Summary (CLM), RR3 local products, Temperature and Precipitation 
Table (RTP), etc.  

For questions on discontinuance of these products, contact: 

Kevin Schrab                            
Observing Services Division Chief
