1. Observed Data updates 
(Dynamic Predictables expresses appreciation and recognizes the contributions to public service that come from public agencies at federal, state, and local levels as well as the many private companies that help advance weather and climate service to the benefit of all.  A special thanks goes to the US Department of Commerce and NOAA through its many agencies.  At different points in this section, we attempt to credit, we hope appropriately and adequately, specific sources in proper context.)

     National Climatic Data Center (NCDC) Climate Division (cirs) data is updated within the first 10 days of the following month.  This monthly climate data listing accumulated precipitation and monthly mean temperature may be accessed directly from NCDC, a division of NOAA in the US Department of Commerce.  For convenience we provide the most recent data here for each of the 344 climate divisions in the continental US.  The original ASCII (plain text) data files from NCDC begin January 1895 and are each approximately 3.5Mb files.  This monthly climate division "cirs" data firms in three steps: the first step as reported here within the first ten days of the current month, a second step reporting usually within the last ten days of the current month, and a third step and usually final firming that occurs five to six months later.

     At NCDC, Climate Divisions of interest may be located with a combined numeric state code, climate division number, and climate variable code:  StCdV with SS ranging from 1 to 48, Cd ranging from 1 to 10, and V being 1 for precipitation and 2 for temperature.

A crossover table (in Courier New font) is provided relating the state name to the state code:

20110905.  DynaPred with 201107 end data adopts the 200703 I2I2I2I4 FORMAT.  If you've been using the previous format, it will probably work in Excel but any machine reading of formats would need to adjust the Read input statements.

###ALERT:  EFFECTIVE MARCH 2007 NCDC-CIRS DATA ADOPTED AN ADDITIONAL DIGIT VARIABLE FORMAT.  Spatial and climate identifiers beginning in leftmost column 1 changed from StCdVyyyy to StCdVVyyyy.  This format change is readily compensated for manually while importing .TXT files into a spreadsheet such as MSExcel.  However, if you're reading this text (ASCII) file into another processing program such as Fortran, C++, etc. then almost all your input READ files formats will need to be changed accordingly.  Beginning with the 5th column first variable (V to VV), then yyyy, and then all the climate variable (e.g. temperature or precipitation) data fields have been shifted one (1) digit to the right in a tabular, ASCII format.
200702 and previous format:

Examples:

Illinois 2003 precipitation, climate division 6, would be left headered by 110612003 where 11 is Illinois (IL), 06 is NCDC climate division #6 and precipitation is climate variable 1, followed by CY 2003.  The twelve columns to the right of the indicator set are the monthly precipitation values (January = 1, February = 2, etc).  Monthly accumulated precipitation is in inches, with missing data indicated by -9.99.  September 2003 (200309) is then 2.60 inches.

11 612003   0.58   1.88   2.55   3.63   4.94   7.15   4.38   5.34   2.60  -9.99  -9.99  -9.99

North Dakota 2003 monthly mean temperature for climate division 4, is indicated by the first nine digits on the left: 320422003 where 32 is North Dakota (ND), 04 is NCDC climate division #4, temperature is climate variable 2, followed by CY 2003.  Monthly mean temperature (simple average of the daily midpoints during the month) in degrees Fahrenheit (F) for September 2003 (200309) is then 59.70 F.  Missing data indicator is -99.90 or -99.9.

32 422003  12.90  10.90  22.80  45.70  54.50  61.70  72.20  74.60  59.70 -99.90 -99.90 -99.9
