SUBJECT:
Change to New 1981-2010 Climate Normals
The NWS will
incorporate the new 1981-2010 Climate Normals into
our climate text products on August 1. The products affected will be:
Daily Climatological Report (CLI)
Monthly Climatological Report (CLM)
Quarterly Climatological Report (CLQ)
Seasonal Climatological Report (CLS)
Annual Climatological Report (CLA)
Preliminary Local Climatological Data
Report (CF6)
Any product
that has data that crosses the August 1 implementation date, such as
the quarterly, seasonal and annual Climatological Reports, will use the new
1981-2010 Climate Normals for required calculations
for the entire period.
Products
issued prior to the change date will not be reissued using the new climate Normals.
Climate Normals are calculated every 10 years and are an average of
30 years of climate data. The
calculations are done by The National Climatic Data Center. More information can be found at;
http://www.ncdc.noaa.gov/oa/climate/normals/usnormals.html
