Metadata about production center and base time of the analysis and/or forecast Information about the NWP model producing the analysis or forecast Resolution at which model is run Grid resolution of distributed data Same as GRIB2 'productionStatusOfProcessedData' Information about the ensemble prediction system Information about the spatial reference system used to go between latitude/longitude and distance on the earth Optional string or numerical value used to represent missing data (ex: -999). Note that missing numerical data can also be represented by including xsi:nil="true" in the tag. Data content of the analysis or forecast. The type can be 'analysis', 'forecast' or 'ensembleForecast' Normally a file would have only one type of data but in some cases it may be desirable to have both an analysis and a forecast. Several disturbances (cyclones) can be included in a single data element. Data on a particular storm (disturbance) Specified by production center or generating application for its own use Basin in which the storm is located at analysis time. Either 3-letter abbreviation or full words are acceptable but full name is preferable. Objective technique used to produce forecast or analysis Position of a disturbance at a particular time Subregion within the basin. Some continents have been included to support extra-tropical storm tracking Used for satellite fixes. 1=eye/geography, 2=eye/ephemeris, 3=well defined circ. center/geography, 4=well defined circ. center/ephemeris, 5=poorly defined circ. center/geography, 6=poorly defined circ. center/ephemeris Site or center where fix was determined Used for aircraft fixes Navigational accuracy Platform for the radar observations Used in ATCF for synoptic fix Data describing the storm's development and status Development status of a disturbance Storm depth Storm category (1-6) Satellite-based Dvorak code for TC intensity Data describing the storm's maximum sustained wind speed Radial distance at which a threshold value is met. This can be within a particular sector or around the full circle. Sector must be specified (NEQ, SWQ, etc., or AAA for full circle). Default sector is "AAA" Data describing the storm's maximum sustained wind speed Temperatures in the storm and nearby environment Minimum sea level pressure Data describing the pressure and radius of the last closed isobar Data describing the cyclone's eye Shape of the cyclone's eye If storm is elliptic then this element describes the long axis If storm is not elliptic then omit this element Data on cyclone phase from Hart et al. 1993 Data describing the storm's speed and direction Data describing the storm's maximum precipitation Dominant precipitation type. If neither "rain" nor "snow" then use "mixed" Data describing the storm's maximum wave height Any comments can be inserted here
