19 REFERENCE NOTES DEFINITIONS NAMES: Name of the city, town or locality. Figures and letters following the station names indicate the distance in miles and direction from the post office or town community center. DIVISIONS: Areas within a state of similar climatological characteristics. Division averages are calculated using data from stations that record both temperature and precipitation (i.e. not precipitation alone). NORMALS: The average value of the meteorological element over a time period. Effective 1 January 1993, the averaging period is 1961 to The normals for National Weather Service localities have been adjusted so as to be representative for the current observation site. MONTHLY DEGREE DAY TOTALS: One heating (cooling) degree day is accumulated for each whole degree that the daily mean temperature is below (above) 65 degrees Fahrenheit. PRECIPITATION: Values shown in hundredths of inches are water equivalent totals, i.e., total of liquid and melted frozen precipitation. In the Monthly Summarized Data table the total snow and sleet values shown in tenths of inches are unmelted amounts. The max depth on ground values of snow and sleet shown in whole inches are cumulative unmelted amounts. The number of days with.10,.50, 1.00 or more refers to water equivalents. PRECIPITATION QUALITY CONTROL: The NCDC quality control process may delete precipitation data that are spatially inconsistent; exceed climatological limits, or are inconsistent with prevailing weather patterns. TEMPERATURE: Original and edited temperature values are given in the Daily Temperature table. Edited values are produced when an original value is missing or when surrounding stations indicated a suspect original value. When a line labeled OBS is present and contains either a daily temperature (suspect) or *** (missing), the temperature appearing directly above, on the line labeled MAX or MIN, is an edited value. Summary temperature information (averages, departures, extremes, monthly degree day totals) is based on the values labeled MAX/MIN. WIND: (As shown in the Evaporation and Wind table) the total wind movement in miles over the evaporation pan as determined by an anemometer recorder located 6-8 inches above the pan. SYMBOLS AND LETTERS USED IN THE INDEX TABLE # Thermometers located in a rooftop shelter. // Rain gage equipped with a windshield AR Observation made after rain has occurred. C Station is equipped with recording rain gage (R) but values in this bulletin are from a non-recording rain gage unless indicated by an R. G Observations appear in the Soil Temperatures table. H Observations appear in the Snowfall and Snow on the Ground table. J Station also published as a Local Climatological Data publication. MID Observation time is midnight. MO Rain gage read once monthly, usually the last day. OC Rain gage readings vary from a few weeks to several months. R Amounts from recording rain gage. SR Observation time near sunrise. VAR Observation time varies. WI Rain gage read weekly or irregularly. WM Rain gage read weekly and last day of the month. SYMBOLS AND LETTERS USED IN THE DATA TABLES (DAILY DATA ARE FOR THE 24 HOURS IMMEDIATELY PRECEDING OBSERVATION TIME.) BLANK Entries in the Monthly Summarized Data table indicate no record. BLANK Entries in the Daily Precipitation and Snowfall and Snow on the Ground tables indicate zero. BLANK Entries in the Daily Temperature table indicate a missing record where an edited value could not be determined. (See *** below) - No record. Data not recorded, determined unreliable by quality control check, or not received in time for publication. + Precipitation or temperature extremes occurred on one or more previous dates during the month. *** Missing original temperature which has been estimated during edit. * Rain gage not read. Precipitation is included in the amount following the asterisks. Time distribution not known. A * preceding the monthly total indicates precipitation amount is being carried forward to next months total, and may include amounts from the previous month(s). // Rain gage equipped with a windshield. A Amount of precipitation is the total of observer s entries for the current month. It may include precipitation that occurred during the previous month. Refer to earlier bulletin to determine date of last reading. (Hawaii stations) B Adjusted monthly value (estimated), (1-7 missing values for wind and evaporation). M Insufficient or partial data. M is appended to average and/or total values computed with 1-9 daily values missing. M appears alone if 10 or more daily values are missing, (8 or more for wind and evaporation). R Amounts from recording rain gage. T Trace. An amount too small to measure. V Includes total for previous month(s). (See * above) SEASONAL TABLES: Monthly and seasonal snowfall and heating degree days for the 12 months ending with the June data are published in the July issue of this bulletin. Cooling degree days for the calendar year are published in the Climatological Data Annual Summary. Information concerning the history of changes in locations, exposure, etc. of substations is kept on file at the National Climatic Data Center. Historical information of regular National Weather Service Offices may be obtained from the Local Climatological Data annual publication. The contents of this publication may be reprinted or otherwise used freely, with proper credit to the National Climatic Data Center. The data are also available in digital form on magnetic tape and diskette.
