Notes
* Important
Web Climate Services Version 2.1 is an attempt to bring metadata from
a number of sources into one location to provide easy access to the
information. The system is still young and improvements will be made as
resources allow. Anywhere you see an * you can click on it to get more
information about the term the * is by. Please see the disclaimer before using information in WebCliServ.
If you have questions or comments about this system, send them to ncdc.webcliserv@noaa.gov. If
you have questions about where you can find or obtain climatic data,
please send those questions to

Automated Surface Observation Stations (ASOS)
The NCDC station history archives do not currently contain ASOS stations. A process has been automated to import these stations into this system from other sources.
Call Sign
The NCDC station history archives do not include international call sign. A process has been automated to identify as many international call signs as possible. A search using international call sign may not locate the desired station.
City
The NCDC station history archives do not include city. A process has been automated to identify city where possible. Cities have been identified in approximately 60% of the station records in the system. A search on city may not return all stations in that city. Example: Cape Hatteras NWS is located in the city of Buxton which cannot be automatically identified.
Cooperative Stations
These stations are identified by a 6-digit number and are part of the National Weather Service's Cooperative Station Network. The first two digits designate a USA state or territory code. The last four digits are assigned to stations within a state in general accordance with the alphabetic order of the station name. A station in this network, as designated by a single Cooperative Station Identifier, can be one site or a series of sites whose locations fall within 2 miles horizontal or 100 feet vertical difference. There are exceptions to this rule, with "climatic compatibility", as determined by the NWS field manager, being the overriding factor.
County
Some records in the NCDC station history archive do not have county identified. Searching by county may not return all stations in that county. Since county names may be duplicated across states, it is recommended that you use the State/County/City option to list stations in a specific county in a specific state.
Credit
The National Climatic Data Center credits Brian Bero (UNC-A Class of 1997) for his work on this system. Brian completed Web Climate Services Version 1.0 as his senior project for the University of North Carolina at Asheville. Brian received the Outstanding Senior Project Award at the annual UNC-A Academic and Leadership Awards banquet. This award recognized Brian's project as the best senior project in the Information Systems track of the Computer Science program.
This project was oringinally supported by a 1996 Department of Commerce Pioneer Fund Award entitled developing "An On-Line Acess/Retrieval System for Agencies with Large and Diverse Databases".
Data Errors
Data errors found in this system should be addressed to ncdc.webcliserv@noaa.gov. Your assistance in identifying any data errors found is appreciated.
Datasets
NCDC has approximately 1000 data sets in both digital and non digital form. Please see the Dataset List for a list of our more popular sets. For additional information on any of our data holdings, contact NCDC.
Disclaimer
The information contained in Web Climate Services Version 2.1 is a "best effort" attempt to provide access to NCDC metadata. The contents of this system cannot be considered as official records. To obtain official records or to verify content found in this system please contact NCDC.
Division
Climate Divisions are standardized regions within each state
designating areas of similar climate regime. The number of climate
divisions in a state varies from one (Rhode Island) to a maximum of ten
(many states). Please note that problems exist with divisions in the
Station History Archives. For more information about Climate Divisions and
associated problems please see Section 6d of the Master
Station History Report).
Elevation
The elevation of the station at ground level. A value of "0" is legitimate (sea level), as are negative values (below sea level). From NWS guidelines ground elevation is generally taken from temperature sensor location at airport sites, and from the rain gage location at other observing sites.
Latitude/Longitude
Up until the past decade, nearly all latitude and longitude values were reported in Degrees, Whole Minutes, and most uses for latitude and longitude information required no higher resolution. In recent years, the availability of Geopositioner (GPS) technology and the demand for more precise location information has increased the precision of these measurements to Whole Seconds.
Period of Record
The period of record indicates the beginning and ending dates for which the station was open. IMPORTANT: The availability
of data from any given station is not directly related to the period of
record. Many stations do not provide data to NCDC. To determine
what data is available for a given station, please check the
stations's Data Inventories. Please contact
NCDC if confirmation of data availability is needed.
Radar Stations (NEXRAD)
The NCDC station history archives do not currently contain NEXRAD stations. A process has been automated to import these stations into this system from other sources.
Sources
The information found in this system is derived from the NCDC station history archives as well as:
- international call signs from the National Weather Service (NWS),
- cities from the United States Geological Survey (USGS),
- State/County Automated Flood Warning System links from the National Weather Service (NWS), and
- station narratives and ASOS/NEXRAD station information from other NCDC files.
State
Searching by state can return many records in some states. You may want to use other methods to narrow your search.
Station
At the present time this system contains records for U.S. controlled stations only. Plans are to add additional stations in the future.
The name is normally in the format of city name + qualifier, where the qualifier differentiates locations among stations or sites having the same town name (e.g. GREENVILLE 1 SW, GREENVILLE 2 NE). Exceptions to the city name convention include some military sites (e.g. LANGLEY AFB), and certain natural features or private holdings in remote areas (e.g. STAMPEDE PASS, JOHNSON RANCH, CAPE HATTERAS).
Station History Archives
The Station History Archives (see Master
Station History
Report) contain information about the present and historical names, identifiers, and locations of approximately 30,000 stations. These stations are located on all continents, but most (>95%) are USA sites. This data base contains information for all stations, including those having either digital or non-digital data archived at the NCDC.
The Master Station History Report (MSHR) data set is updated monthly by the NCDC Data Base Management Branch as part of the Station History Information Processing System (SHIPS).
Station Type
A loose station classification scheme for non-Cooperative network stations based on NWS, Department of Defense (DOD) and NCDC past and present schemes. The intent of depicting station types is to inform the user of the general nature of a given station.

WBAN ID Numbers
A five-digit station identifier used at NCDC for digital data storage and general station identification purposes. WBAN is an acronym, invented in the 1950's, which stands for Weather-Bureau-Army-Navy. WBAN station numbers were first used as identifiers for stations reporting meteorological observations on the then-standard WBAN series of forms (e.g. WBAN 10A, 10B, and 10C).
WBAN numbers were the first major attempt at a coordinated station numbering scheme among several weather reporting authorities. Original participants in the WBAN number plans were the United States Weather Bureau, Air Force, Navy, and Army; the Canadian Department of Transportation; and certain German and Korean stations in close cooperation with the US Weather Services.
World Meteorological Organization (WMO) ID Numbers
A five-digit station identifier assigned by the World Meteorological Organization (WMO), used for international weather data exchange and station documentation. The authoritative documentation of the WMO Station Identifier is the publication: Volume A, Observing Stations, WMO - No. 9, World Meteorological Organization, Geneva Switzerland (issued periodically).
Some, but not all, WMO station identifiers are contained in this data set report (generally, for the approximately 300 US NWS first order stations). Dates associated with the WMO station identifier are unreliable. Information from the WMO Volume A publication has not been routinely incorporated into the NCDC station history data base.
Zip Code
The NCDC station history archives do not include city or zip code. A process has been automated to identify city where possible and to provide search capabilities by zip code. Cities have been identified in approximately 60% of the station records in the system. A search on zip code may not return all stations in that city. Example: Cape Hatteras NWS is located in the city of Buxton which cannot be automatically identified.
