The "Multi-Agency Profiler" dataset includes meteorological "profiles" from several different kinds of observing systems, primarily including wind and virtual temperature data from boundary layer profiling radars, and wind data from SODARs. Each station can have up to three modes of operation for winds, and one mode for Radio Acoustic Sounding System (RASS) temperatures. The number of levels at which data are obtained, the spacing between the levels, etc., are all a function of the "mode parameters" specified for each station, and available to the user via the variable codes listed above. The user can choose to retrieve each mode separately, or can request an integrated profile where the MADIS API will return all modes (wind and RASS) sorted in ascending order by height. The level type variable can be obtained by users wishing to know which modes were actually used in the integrated profile. The station type variable is used to specify the type of observing system that's in use, with these code values: Value Meaning ----- ------- 1 Boundary layer profiler 2 UHF tropospheric profiler 3 VHF tropospheric profiler 4 SODAR 5 Unspecified The mode parameters, consensus numbers, etc., are only used for the profiler station types. The U/V gust and standard deviation variables, and the mixing layer elevation, only apply to SODAR stations. 2. All of the wind mode parameters are specified individually for each antenna beam direction. As there can be up to five antenna beams, an array of 5 elements will be returned for each station. 3. Depending on the station type, either u/v wind components or wind speed and direction may be stored in the database. The user can select either form of the wind data and it will be calculated and returned from whichever form is stored in the database. The results of QC checks applied to any form of the winds will be used, and if one of the map projections has been selected via the MSETDOM call, the winds will be rotated to match the projection. 4. The w wind component is actually the radial velocity measured with the vertically-pointing antenna beam (with the sign negated). Because the level of error in the observed velocities is of the same magnitude as that expected for this observation, the user should take care when interpreting this variable. 5. The true vertical coordinate is height. If the user selects pressure as the vertical coordinate, the heights are converted to pressure using the U.S. Standard Atmosphere calculation. 6. The basic averaging technique employed for profiling radars is the "consensus average" applied to the radial velocities for each antenna beam, in the case of winds, or to the temperatures for RASS. This method examines the number of records taken to locate the largest subset of data values that are within a given window of each other. The number of values in the subset is called the "consensus number". The consensus test is passed when the consensus number is at least the minimum number specified for the given station/beam/mode, otherwise the test has been failed and no average value is created. 7. The radial velocity uses the convention that positive values are towards the radar receiver (e.g., the ground), and negative values are away from the receiver. 8. Level type codes: Value Meaning ----- ------- 1 Wind mode 1 2 Wind mode 2 3 Wind mode 3 4 RASS mode 1 9. The profilers can have up to 5 antenna beam directions. Typically, for a 5-beam system, 2 beams will be in the N/S plane, 2 in the E/W plane, and one beam will point in the vertical direction. The names of the beams generally indicate the plane (e.g., "NS 1" and "NS 2"), while the azimuth and elevation variables define the exact pointing direction. 10. Profiler data are averaged over some time interval, specified in the averaging period variable. By convention, the observation time is the end of the averaging period. For example, a 30-minute average with observation time 12:00 covers data averaged over 11:30 - 12:00. 11. Vertical correction flag codes: Value Meaning ----- ------- 1 Wind vertical correction: off 2 Wind vertical correction: on 3 Wind vertical correction: unknown The profiler vertical correction, if selected, means that the radial velocities for the oblique beams are corrected for vertical motion using the radial velocity from the vertical beam. 12. All times reported in the MADIS API are in Universal Coordinated Time, with the format of "YYJJJHHMM", where: YY = 2-digit year (good from 1980 - 2179) JJJ = Julian date of the year (1-366) HH = Hour (0-23) MM = Minute (0-59) If the time is missing, the 9-character field will be set to all blanks, e.g., " ". Users of the MADIS API mapdump program will get the time output in their chosen format, either YYJJJHHMM or YYYYMMDD_HHMM. * The QC information is only available with the FSL database.
