gov.noaa.ncdc:C00360 National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce Unknown tabular digital data http://www.ncdc.noaa.gov Hourly Precipitation Data - Special ASOS Network is a digital data set archived as DSI-3241 at the National Climatic Data Center (NCDC). The data were recorded on paper charts by the Universal Rain Gauge, which is an older type of rain measuring device. This gauge has a pen arm that continuously scribes a line on a chart that is mounted on a rotating drum. The position of the line corresponds to the weight of the contents of the gauge holding bucket. The gauge has a 0.01 inch resolution. DSI-3241 data is from US first order Automated Surface Observing System (ASOS) stations, but are separate from ASOS observations; and the earliest data at a station generally coincide with conversion to ASOS. The earliest data is May 1995. The National Weather Service has continued to fund the operating expenses of Universal Rain gauges at about 150 first order stations that are now ASOS. All stations are located in the 48 contiguous states of the United States, plus Alaska. This data will continue to be available as long as funding continues. Some stations have sent data sporadically. Only partial data may be available for a given data month. No data for the July 1995 data month is available. To make a wide range of climatic data available to researchers and the public. data set C00360 RAIN GAUGES ASOS > Automated Surface Observing System National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce 19950501 Present Ground Condition In work As Needed -170.0 -65.0 72.0 25.0 ISO 19115 Topic Category climatologyMeteorologyAtmosphere 004 DIF Discipline Keyword Thesaurus Earth Sciences > Atmosphere > Meteorology Earth Sciences > Atmosphere > Climatology Earth Sciences > Atmosphere > Weather Earth Sciences > Land > Hydrology GCMD Sciences Keyword Valids EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION AMOUNT GCMD Location Valids MID-LATITUDE POLAR NORTH AMERICA UNITED STATES OF AMERICA GCMD Location Valids LAND SURFACE Automated Surface Observing System ASOS RAIN GAUGES 1 None None Not provided Unknown Completeness information not available.

Field 008Positions 28-30 Number- This denotes the actual number ofReported-Values values. Range of values is 2 to 25.NOTE: A record may contain fewer or more data values than you might expect. A daily record of hourly values may contain as few as 2 data values or as many as 25 data values. Only hours which have recorded precipitation are included (no entry for zero precipitation). There are some exceptions: 1) the begin and end hours of a missing, accumulation or deleted period are reported, 2) the first day and hour of each month that a site is in operation, whether precipitation occurs or not is included. See Flag 1 definitions for further details.Field 009 Positions 31-34 Time-Of-Value - This contains the ending time of precipitation 0100-2500. (Example, hour 0200 is defined as the period 0101-0200) The hour is left justified, zero filled. Hour 2500 contains the daily total, and it will always be the last value of a record. Midnight = 2400. Local Standard Time in use.Field 010 Positions 35-40 Data-Value - The actual precipitation data value. The data value portion is a five-digit integer with a leading algebraic sign. The sign is blank for positive and "-" represents negative values("-" never used in this data set). Units and decimal position, if appropriate, are indicated in the ELEMENT-UNITS field described in Field 004. Range = 00000-99999. 00000 will be used only on the first hour of each month unless there is precipitation during that hour, in which case the measured value will be provided. On other days during the month without precipitation, no entry will be made. 99999 indicates that the DATA-VALUE is unknown. Beginning with the July 1996 data month, traces of precipitation are archived for first order stations. A trace is indicated by 00000 recorded in this element (Data-Value) and a "T" in FLAG1.Field 011 Position 41 FLAG1 - The Data Measurement Flag.FLAG1 Table (Data Measurement Flag for Hourly Data-Values)a Begin accumulation. A value of 99999 accompanies this flag. For DSI-3241, it indicates that the accumulation has begun sometime during the hour.A End accumulation (amount is associated with this flag). For DSI-3241, it indicates the accumulation has ended sometime during the hour. Accumulated period indicates that the precipitation amount is correct, but only the exact beginning and ending times are known. An accumulated daily value of 00000 with a "T" flag can occur.[ Begin missing period during the hour (inclusive). A value of 99999 accompanies this flag] End missing period during the hour (inclusive) A value of 99999 accompanies this flag. g Only used when a station reports no precipation for the month.T Indicates a "trace" amount. Data value will be zero. b (blank) no Flag needed. FLAG1 Table (Data Measurement Flag for Daily Total Data-Values)I Incomplete or Inexact daily total occurring only with hour 2500. Value is not a true 24-hour amount. One or more periods are missing and/or an accumulated amount has begun but not ended during the daily period. P A daily total excludes erroneous values (those flagged q, Q, {, or }. A "P" flag will also be present when an accumulation has ended (but not begun) during the daily period. T TRACE, Flag1 will contain a ?T? flag in the daily total if no values other than a TRACE occurred during the 24 hour period. An accumulated daily TRACE can occur. b (blank) no Flag needed.
