STAR ‑‑ STability ARray, a joint frequency distribution summary of stability category, wind speed and wind direction. The STAR data are used as input for the ISC Long Term dispersion model.
Station Identification ‑‑ An integer or character string used to uniquely identify a station or site as provided in the upper air (TD‑5600 and TD‑6201), mixing height (TD‑9689), and surface weather (CD‑144 and TD‑3280) data formats available from NCDC. There are no standard station numbers for on‑site data or card image/screening data, and the user may include any integer string
Subdirectory ‑‑ A directory below the root, or highest level, directory or another subdirectory, used for organization of files on a storage medium such as a PC hard disk.
Surface Weather Observations ‑‑ A collection of atmospheric data on the state of the atmosphere as observed from the earth's surface. In the U.S. the National Weather Service collect these data on a regular basis at selected locations.
Surface Roughness Length ‑‑ Height at which the wind speed extrapolated from a near‑surface wind speed profile becomes zero.
Syntax ‑‑ The order, structure and arrangement of the inputs that make of the input runstream file, specifically, the rules governing the placement of the various input elements including pathway IDs, keywords, and parameters.
TD‑1440 Format ‑‑ A format available from NCDC for summarizing NWS surface observations in an 80‑column format; the CD‑144 format is a subset of this format. This format has been superseded by the TD‑3280 format.
TD‑3280 Format ‑‑ The current format available from NCDC for summarizing NWS surface weather observations in an elemental structure, i.e., observations of a single atmospheric variable are grouped together for a designated period of time.
TD‑5600 Format ‑‑ A format available from NCDC for reporting NWS upper air sounding data. This format has been superseded by the TD‑6201 format.
TD‑6201 Format ‑‑ The current format available from NCDC for reporting NWS upper air data. The file structure is essentially the same as the TD‑5600 format except that there is more quality assurance information.
