BENJAMIN ORG: FSL DATE: 05-11-10 C C ABSTRACT: Dump MADIS snow station info, observations, and quality C control (QC) information for a single time, based on the user's C selections specified in a text parameter file. The program is also C meant as a tutorial to demonstrate how a user can use the MADIS C library calls to write his or her own programs. C C PROGRAM HISTORY LOG: C 08-07-25 L.

C C Initialize the MADIS snow subsystem C ------------------------------------ C C The user selects the "subsystem" to be initialized by C specifying the following arguments to the MINIT call: C C 1) Name of the subsystem: C C 'SFC' Surface C 'RAOB' Radiosonde C 'NPN' NOAA Profiler Network C 'ACARS' Aircraft data (ACARS, AMDARS, etc.) C 'ACARSP' Aircraft data profiles at airports C 'MAP' Multi-Agency Profilers C 'HYDRO' Hydro C 'RDMTR' Radiometer C 'SATWND' Satellite wind C 'SATSND' Satellite soundings C 'SATRAD' Satellite radiance C 'SNOW' Snow (used here) C 'WISDOM' Wisdom balloon wind C C 2) Error handling (.true./.false.): C C If ".true.", then error messages will be written to standard C output. If ".false.", no error messages will be output (but C ISTATUS will still contain an error code). The error codes C can be found in errors.txt in the doc directory. C The necessary inputs are found in the parameter file, along with C a number of lines of explanation, section delimiters, etc. meant C to aid readability. Throughout this program, we'll be skipping C non-input lines, reading necessary inputs, and checking for I/O C errors. Otherwise, the validity of most of user's choices will C be tested by the affected MADIS library routines. Invalid choices C will be reported to standard output, and in most cases, the C program will then stop. 145 format(a) write(*,500)'MADIS SNOWDUMP Activity Log' 500 format(1x,a) write(*,500)'----------------------------' 501 format(/,1x,a) 401 format(3x,a) db = 'FSL' CALL MINIT('SNOW',db,.true.,istatus) if(istatus.ne.success_p)stop C----------------------------------------------------------------------- C OPTIONAL MADIS SETUP CALLS C ------------------------- C C Optional calls to limit which obs MADIS will return. C These can be selected at any time in the code, C and will then take effect upon the next call to C MSNOWSTA (see below). The default behavior (what C happens if you don't call the routine) is described C below. C C Select time window C ------------------ C C The user selects the nominal time of the data to be returned C when using MADIS routines to read obs and station information. C Time "windowing" is used so that the MADIS routines will C know how close in time each station's observation time needs C to be to the nominal time in order to be included, and whether C or not duplicate records from the same station that are within C the time window should be included. The time window is C specified with the MSETWIN subroutine, which allows the user C to select the number of minutes before and after the nominal C time to be used for the window, and how duplicates should C be handled. For more details, see msetwin.txt in the C doc directory. C C If MSETWIN is not called, the default will be to return all C records (including multiple reports from the same station) C in the file containing the nominal time. For snow stations, C data will cover from the hour until 59 minutes after the hour. C C Snow stations report observation times around the hour, and C many stations report multiple times per hour, so different C time window specifications can produce very different sets C of data. C C The following sample MSETWIN call will return only one record C per station within the specified time window (-30 minutes --> C nominal time --> +30 minutes). If a station has multiple reports C within the time window, only the latest one within the window C will be returned (RECWIN = 3).

The MSETSNOWPVDR subroutine C can be used to select only a subset of the total by C specifying which providers are to be included or C excluded. C C If MSETSNOWPVDR is not called, the default is to enable C data from all snow providers.

Different variables C have different levels of QC, or "stages", applied to them. C For example, the accumulated precipitation variables have level 1 C checks (validity). Note that each level of QC incorporates the C previous levels, i.e., an ob that has passed level 3 has also C passed any applicable level 1 and 2 checks. At the current C time, only stage 1 checks are available for snow data. See C snow_qc_variable_list.txt in the doc directory for more C information. C C Each call to MGETSNOW will return obs and associated QC C information. If the user doesn't want to interpret the QC info, C he or she can limit the returned obs to selectable levels of C quality. In that case, obs that don't meet the selected QC level C will be replaced with missing data flags, and the QC information C itself doesn't need to be examined by the calling program. C C If MSETQC is not called, all obs will be returned (along with QC C info). C C There are three ways that the user can request and process the QC C information: C C 1) Don't call MSETQC at all, and examine the QC info before C deciding whether or not to use each observation. This C allows the calling program the maximum amount of control C over what's available. C C 2) If you know ahead of time that the same level of QC is C available for all variables you'll be using, call MSETQC C one time to select the desired QC level. Note that the C level selected by MSETQC will stay in effect until the C next time MSETQC is called. C C 3) To require that all variables pass the highest level C of QC that are specified for them, call MSETQC one time C and select QC level 99. C C User's of MADIS data who want the data filtered by QC results, C but don't want to interpret the QC information themselves, should C call MSETQC one time and select QC level 99.

(MCHGTIM) C - Translate the native format to integers representing year, C month, day, hour, and minute. (MINTTIM) C - Translate integers representing year, month, day, hour and C minute into the native format. (MCHRTIM) C - Translate between Julian and Month/Day formats (MTRNTIM) C C See time_routines.txt in the doc directory for details on how C to use these calls.
