I. INTRODUCTION
The Regional Profile Database is a VSAM based random access database ofNGM forecast sigma layer and diagnostic data at selected locations overNorth America. This database was designed as the basis for generating newmodel products which are not possible with the normal 12 hour griddedfields on pressure surfaces. Meteograms ( time histories ), soundings andother products are available for operational and R&D use. This TPB willdescribe the contents of the database, how to access it and present a fewexamples of products from the database.
I I. CONTENTS OF THE DATABASE
The database has two components:
- PROFOPN
- PROFSYN
They have different characteristics based on their anticipated use andare described below.
a) PROFOPN
This component of the database contains the entire NGM sigma layerspecification of momentum, temperature, pressure and moisture as well asmany other diagnostic quantities at a network of station over North America.These quaitites are derived via bi-linear interpolation from the model gridsto the station latitude and longitude. The information is stored with a timefrequency of 1 hour and is available for the latest 18 cycles ( or 9 days ). TheWMO station number, latitude and longitude, 3 letter identifier anddescriptive name of the 181 stations in the network is presented in Table l.Figure 1 shows the geographical distribution of the stations. All reasonablereauests for additions to the list of stations will be honored within 24 hours.
There are 49 profiles ( 0 hour plus every hour out-through 48 hours ) -
available every cycle. Since there are 181 stations for the latest 18 cycles of -the RAPS the total number of profiles is
49 181 18 159,642.
This component of the database has a high temporal resolution whichallows for detailed examination of the forecast. The length of the database
-( 9 days ) is such that post mortems of significant weather events is possiblewithout having to rerun the NGM.
b) PROFSYN
This component of the database contains the profiles at the same networkof station as PROFOPN except the information is stored every 12 hours outthrough 48 hours. The information is available for the latest 72 cycles ( 36days ) as opposed to the 18 cycles of PROFOPN. The number of profiles istherefor
5 * 181 * 72 = 65,160.
Since verification in the form of a 00 hour forecast is available only every12 hours, this component of the database is used for verifying the NGMforecast of length 12, 24, 36 and 48 hours. With 36 days online, monthlysummaries of the performance of the NGM at any of the 181 stations in thedatabase is possible.
I111. ACCESSING THE DATABASE - RETRIEVAL OF RAW NUMBERS
Access to the database, through the NMC NAS 9000 computer system, forthe purpose of retrieving the actual forecast values is made possible througha series of subroutines. The current library of routines will undoubtedlygrow and updated versions of this document will be prepared. Currently, thefollowing routines are available.
1) GUVTQP - returns the 16 sigma layer values of zonal andmeridional wind, temperature, specific humidityand pressure and the surface pressure, surfaceelevation and skin temperature.
2) GCLDS - returns the fractional coverage of low, middle andhigh clouds and the pressure of the sigma layer
where they are present from the interactive cloudmodel in the NGM.
3) GRDTN - returns the 16 sigma layer values of totalradiational heating.
41I GPRCP - returns the accumulated grid scale and sub-gridscale precipitation over the past hour.
5) GSEB - returns the terms of the surface energy budget andthe skin and sub-soil temperatures from thesurface energy budget in the NGM.
These subroutines are called by supplying the year, month, day, and hourthat the forecast was initialized plus the forecast hour and station number.The information listed above plus an error flag is returned. Detaileddescriptions of the calling sequence plus the physical units of the returnedquantities are presented in Appendix A ( see TPB #363 for details regardingradiation and other physical processes in the NGM). Appendix B providesinformation on the structure of the VSAM files.
The following program and JCL demonstrates how to retrieve the sigmalayer values of wind, temperature, moisture and pressure as well as surfacepressure, terrain elevation and skin temperature using GUVTQP. This job issetup for an user onsite at NMC and must run on the NAS 9000 computersystem: the location of the database. Remote users of the NAS 9000 systemwill need to adjust the JCL appropriately.

During the LINK EDIT step, you must include member RPACODE from thefollowing load library..
NWS.WD22.JJT.REG.LOADLlB.
This member contains the object code for the routines to read the database.
During the GO step you must define unit 99 as the database dataset. For thetwo components of the database listed above the datasets are
NWS.WD22.JJT.REG.PROFOPN.CLUSTER
NWS.WD22.JJT.REG.PROFSYN.CLUSTER.
Choose one or the other depending on your need. In the above example thehourly component, PROFOPN, is used.
IV. ACCESSING THE DATABASE - NMCiDAS GRAPHICS
Graphical display of the raw data in the database is possible through theNMCiDAS graphics package of Development Division. Meteograms ( timehistories ), time/height crossections and sounding plots are available at anyof the 181 stations in the database. Figures 2 - 5 present examples of theoutput. Appendix C contains the documentation of the NMCiDAS commandsrelative to the database. Additional information is available from theDevelopment Division. ( This capability is available to those physicallylocated in the World Weather Building).
V. ACCESSING THE DATABASE - VDUC
Those users on the VDUC loop may access the database through a series ofVDUC commands which have been developed in the Development Division ofNMC. These commands are evolving rapidly and interested individualsshould contact Development Division for the most recent versions of thecommands.
VI. ACCESSING THE DATABASE - PC PLOTTING PROGRAM
Remote sites with access to the NMC NAS 9000 system can easily accessthe database and plot soundings using a plotting package developed for anIBM PC or MS DOS compatible clone. The general procedure would be tologon the NAS 9000 system and run an existing program in TSO foregroundto extract the vertical profiles of wind, temperature, moisture and pressurefrom the database for the desired forecast. This information would bedownloaded to a PC and and the sounding program would be executed on thePC to plot the soundings either on the CRT or line printer. A documentationof the program is included in Appendix D. A demonstration disk of thesounding plotting program with several data file from a recent NGM forecastis available upon request.

EXPLANATION:
This command is used for plotting a meteogram forecast from oneof the model profile archives. The profile archives containsigma level utvtq and p as well as many surface quantities.Several diagnostic variables are available as well. The data may
be plotted as a single level time series or as a multi-level time
section.
PARAMETER DESCRIPTION:
STATION - the block and station number or three letter identifierof the forecast station.
DSI - dataset index specifying the model run and starting date.
NPARMS - the number of parameters (Tn and Ln combinations) to beincluded in the diagram.
Tn - type specifiers
Ln - level sDecifiers
The following types are available for the following levels (leveldefinitions follow):

LEVEL DEFINITIONS:
is] - individual sioma level. Thi results in a time
ser i es.(1 = isl = "IZ
where NZ is the total number of model sigma levels.
SFC - surface. For surface quantities only.MSL - mean sea level. For pressure only.
ALL - all vertical levels. This results in a time section
with vertical range from 1050 mb to sigma level NZ.
TROFP - all vertical levels to the tropopause. This resultsin a time section with vertical range from 1050 mb
to 200 mb.thick - all vertical levels bounded by the pressure levels
specified by thick.thick = LL*10 + UL/L10
where LL is the lower level in mband UL is the-upper level in mb.
any - anything, but something must be specified.(INFO works well)
