INTRODUCTION

The Regional Profile Database is a VSAMbased random access database of NGMforecast sigma layer and diagnostic data at selected locations over North America. This database was designed as the basis for generating new model products which are not possible with the normal 12 hour gridded fields on pressure surfaces. Meteograms ( time histories ), soundings and other products are available for operational and R&Duse. This TPBwill describe the contents of the database, how to access it and present a few examples 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 and are described below.

a) PROFOPN

This component of the database contains the entire NGMsigma layer specification of momentum, temperature, pressure and moisture as well as many other diagnostic quantities at a network of station over North America.

These quaitites are derived via bi-linear interpolation from the model grids

to the station latitude and longitude. The information is stored with a time frequency of 1 hour and is available for the latest 18 cycles ( or 9 days ). The WMOstation number, latitude and longitude, 3 letter identifier and descriptive name of the 181 stations in the network is presented in Table l. Figure 1 shows the geographical distribution of the stations. All reasonable reauests 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 RAPSthe total number of profiles is

49 181 18 159,642.

This component of the database has a high temporal resolution which allows for detailed examination of the forecast. The length of the database - ( 9 days ) is such that post mortems of significant weather events is possible without having to rerun the NGM.

b) PROFSYN

This component of the database contains the profiles at the same network of station as PROFOPN except the information is stored every 12 hours out through 48 hours. The information is available for the latest 72 cycles ( 36 days ) as opposed to the 18 cycles of PROFOPN. number of profiles is The

therefor

5 * 181 * 72 = 65,160. Since verification in the form of a 00 hour forecast is available only every 12 hours, this component of the database is used for verifying the NGM forecast of length 12, 24, 36 and 48 hours. With 36 days online, monthly summaries of the performance of the NGMat any of the 181 stations in the database is possible.

I111. ACCESSING THE DATABASE - RETRIEVAL OF RAW NUMBERS

Access to the database, through the NMCNAS 9000 computer system, for

the purpose of retrieving the actual forecast values is made possible through

a series of subroutines. The current library of routines will undoubtedly grow and updated versions of this document will be prepared. Currently, the following routines are available. 1) GUVTQP- returns the 16 sigma layer values of zonal and meridional wind, temperature, specific humidity and pressure and the surface pressure, surface

elevation and skin temperature.

2) GCLDS - returns the fractional coverage of low, middle and high clouds and the pressure of the sigma layer

where they are present from the interactive cloud

model in the NGM.

3) GRDTN - returns the 16 sigma layer values of total

radiational heating.

41I

GPRCP - returns the accumulated grid scale and sub-grid scale precipitation over the past hour.

GSEB

5)

- returns the terms of the surface energy budget and

the skin and sub-soil temperatures from the surface energy budget in the NGM.

These subroutines are called by supplying the year, month, day, and hour that the forecast was initialized plus the forecast hour and station number.

The information listed above plus an error flag is returned. Detailed descriptions of the calling sequence plus the physical units of the returned quantities are presented in Appendix A ( see TPB #363 for details regarding radiation and other physical processes in the NGM). Appendix B provides information on the structure of the VSAM files. The following program and JCLdemonstrates how to retrieve the sigma layer values of wind, temperature, moisture and pressure as well as surface pressure, terrain elevation and skin temperature using GUVTQP. This job is setup for an user onsite at NMCand must run on the NAS 9000 computer system: the location of the database. Remote users of the NAS 9000 system will need to adjust the JCLappropriately.

from the During the LINKEDITstep, you must include member RPACODE following load library..

NWS.WD22.JJT.REG.LOADLlB.

This member contains the object code for the routines to read the database.

During the GOstep you must define unit 99 as the database dataset. For the two 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 the is hourly component, PROFOPN, used.

IV. ACCESSING THE DATABASE - NMCiDAS GRAPHICS

Graphical display of the raw data in the database is possible through the graphics package of Development Division. Meteograms ( time NMCiDAS histories ), time/height crossections and sounding plots are available at any of the 181 stations in the database. Figures 2 - 5 present examples of the commands output. Appendix C contains the documentation of the NMCiDAS relative to the database. Additional information is available from the Development Division. ( This capability is available to those physically located in the World Weather Building).

V. ACCESSING THE DATABASE - VDUC

Those users on the VDUC loop may access the database through a series of VDUC commands which have been developed in the Development Division of NMC.These commands are evolving rapidly and interested individuals should contact Development Division for the most recent versions of the commands.

VI. ACCESSING THE DATABASE - PC PLOTTING PROGRAM

Remote sites with access to the NMC NAS 9000 system can easily access the database and plot soundings using a plotting package developed for an IBM PCor MS DOS compatible clone. The general procedure would be to logon the NAS9000 system and run an existing program in TSOforeground to extract the vertical profiles of wind, temperature, moisture and pressure from the database for the desired forecast. This information would be downloaded to a PC and and the sounding program would be executed on the PC to plot the soundings either on the CRTor line printer. A documentation of the program is included in Appendix D. A demonstration disk of the sounding plotting program with several data file from a recent NGMforecast is available upon request.

EXPLANATION:

This command is used for plotting an atmospheric sounding. Up to two soundings may be plotted on either a skew-T or Stuve

diaqram. The plotted data may be from the NMCIDAS observed data database, model output from the profile archives or from an unformatted file. PARAMETER DESCRIPTION: STATION - the block and station number or three letter identifier of the forecast station.

TYPE - type of diagram, either SKEWT or STUVE. PSPEC - panel specification, either 11 or 12 or 22

11 - one sounding only - temperature will be solid;
