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

OCWWS, Silver Spring, MD
