EMSHR Global Station Locations and Metadata 1738 to Present

This layer contains present and historic locations and metadata for weather stations from the Enhanced Master Station History Report (EMSHR) managed by NOAA NCEI. Use this layer to join weather or climate information from the station records available from the various observation programs. For instance: Global Historical Climatology Network - Daily (GHCN-Daily) World Meteorological Organization Standard Normals Applied Climate Imformation System (ACIS) (U.S. Only) Cooperative Observer Network (COOP) Weather stations are moved for a variety of reasons, sometimes several kilometers from their previous location. Thus, it is often important use the exact location of the station and its context when conducting analysis of the values observed at that location. This layer contains one point for each location and date range where a given weather station has been or is currently located. Below are the field names and description of the data in each field: NCDC - NCEI Unique ID: Unique identifier of source NCEI system. GHCN-D ID: Populated if station is included in GHCN-Daily dataset. ICAO ID: Used for geographical locations throughout the world, managed by the International Civil Aviation Organization. WBAN ID: Assigned by NCEI, used for digital data storage and general station identification purposes. FAA ID: Alpha-numeric, managed by USDT Federal Aviation Administration used for site identification of sites vital to navigation. Commonly referred to as "Call Sign". NWSLI ID: Alpha-numeric, location identifier assigned by the National Weather Service for use in real-time data transmissions and forecasts. WMO ID: Assigned by World Meteorological Organization, used for international weather data exchange and station documentation. COOP ID: Assigned by NCEI, first 2 digits represent state, last 4 digits are assigned numerically by alphabetical ordering of the station name. Transmittal ID: Holds miscellaneous IDs that do not fall into an officially sourced ID category that are needed in support of NCEI data datasets and ingests. Principal Station Name: Name of station, upper case may contain characters, numbers or symbols. Begin Date: Beginning date of record, set to 10101 if date is unknown. End Date: Ending date of record, set to 99991231 if station is currently open. Latitude (dd): Decimal degree latitude, "-" indicates South. Longitude (dd): Decimal longitude, "-" indicates West. Ground Elev. (ft): Ground elevation. For Coop network, average elevation of the ground in a 20-m (60-ft) circle around the primary rain gauge. For 1st and 2nd Order stations, elevation of the official temperature sensor for the station. Ground Elev. (m): Ground Elev. (ft) converted to meters. U.S. Climate Division: Usually contains a number between 1 and 12 indicating climate division as determined by master divisional reference maps. Assigned by NCEI. Relocation Note: Distance and direction of station relocation expressed as a distance value (1-4 characters), space, distance units (2 character abbreviation), space, and direction (1-3 character 16-point cardinal direction). Date of relocation indicated by begin date of record. Location Precision: Indicates precision of source lat and lon using the below codes: DD Whole Degrees DDMM Degrees, Whole Minutes DDMMSS Degrees, Whole Minutes, Whole Seconds DDd Decimal Degrees, to Tenths DDdd Decimal Degrees, to Hundredths DDddd Decimal Degrees, to Thousandths DDdddd Decimal Degrees, to Ten Thousandths DDddddd Decimal Degrees, to Hundred Thousandths DDMMm Degrees, Decimal Minutes to Tenths DDMMmm Degrees, Decimal Minutes to Hundredths DDMMmmm Degrees, Decimal Minutes to Thousandths DDMMSSs Degrees, Minutes, Decimal Seconds to Tenths DDMMSSss Degrees, Minutes, Decimal Seconds to Hundredths DDMMSSss Degrees, Minutes, Decimal Seconds to Hundredths GHCN-D IDs: This was added by Esri as an aid for database management. 1 = NCDC ID has two or more GHCN-D IDs. 0 = NCDC ID has 0 or 1 GHCN-D ID.
