Announcements
This data is provided as part of the GOES-R Proving Ground. For assistance and suggestions on obtaining and using the data, please contact Jordan Gerth.
This data has been undergoing evaluation at the National Weather Service in Milwaukee/Sullivan since 2009.
In addition, this data was be evaluated as part of the Experimental Warning Program at the Storm Prediction Center and National Severe Storms Laboratory Spring Experiment and Hazardous Weather Testbed in 2010.
In addition to AWIPS, this data and a short archive is also available online:
- CIMSS Convective Development Nearcasting Model (CCDNM) via CIMSS Model Analyses and Forecasts
Acquiring Data at a NWSFO
GOES-East Sounder data is currently available to Weather Forecast Offices in Central Region, Eastern Region, and Southern Region, while GOES-West Sounder data is currently available to Western Region. We are unable to supply this to Alaska Region or Pacific Region WFOs at this time. Data is transmitted hourly in GRIB2 format on the EXP feed of the Local Data Manager (LDM). This is not an operational dataset, so unplanned data errors and outages may result. Contact Jordan Gerth once you are receiving data so we can add your office to the e-mail announcement list. We value any feedback.
The Space Science and Engineering Center is not continuously staffed. Consequently, data outages and processing issues may result. This product should be considered non-operational. Required LDAD Configurations
Perform the following actions to configure your Local Data Acquisition and Dissemination (LDAD) server.
In /data/fxa/LDAD/data as user ldad on server px2:
- Append to LDADinfo.txt
In /awips/ldad/bin as ldad on px2:
- Add preProcessNRCAST.pl and assign executable permissions
- Execute "stopLDAD.sh;startLDAD.csh" to restart the LDAD service
In /usr/local/ldm/etc as ldm on ls2:
- Modify ldmd.conf (position sensitive; change ldm.crh to your regional LDM server)
- Change "ECON" to "WCON" for offices in Western Region (GOES-West Nearcast)
- Append to pqact.conf
- Change "ECON" to "WCON" for offices in Western Region (GOES-West Nearcast)
- Copy ldmd.conf and pqact.conf to ls3 with scp
- Execute "ldmadmin restart" to restart the LDM service
- With "ldmadmin watch -f EXP", watch the LDM queue up to 20 minutes for CONVECT data (may take longer)
A zip file of these is available.
Required AWIPS Customizations
Perform the following actions to configure your Advanced Weather Interactive Processing System (AWIPS) workstations/servers.
In $FXA_CUSTOM_FILES as fxa (should be mounted on any workstation/server):
- Append to browserFieldMenu.txt to construct the volume browser menus
- Append to browserPlanViewMenu.txt to add levels to the volume browser
- Append to dataFieldTable.txt to add new fields
- Append to gridImageStyle.rules to set the image display
- Append to gridPlaneTable.txt to add new planes
- Append to localGridSourceTable.txt to add the grid source
- localGridSourceTable.txt for offices in Western Region (GOES-West Nearcast)
- Add nrcast.cdl to create the netCDF template
- Add nrcast.sup to provide supplementary mapping information
- nrcastw.sup for offices in Western Region (GOES-West Nearcast)
- Modify virtualFieldTable.txt (position sensitive; new variables section)
- Append to virtualFieldTable.txt (near or at end)
Optional — You may also wish to append "NRCAST" to activeGridSources.txt
In $FXA_HOME/data as fxa on dx3 (runs Grib2Decoder):
- Modify grib2Grids.txt (position sensitive)
- grib2Grids.txt for offices in Western Region (GOES-West Nearcast)
- Modify grib2Models.txt (position sensitive)
If grib2Models.txt exists in $FXA_CUSTOM_FILES, you will have to reconcile it with the default in $FXA_HOME/data prior to localization.
A zip file of these is available.
When complete with the changes, run '$FXA_LOCALIZATION_SCRIPTS/mainScript.csh f -dataSups -tables -grids -dirs' on dx3, then '$FXA_LOCALIZATION_SCRIPTS/mainScript.csh f -dataSups -tables -grids' on all lx and na workstations. Restart Grib2Decoder when finished (kill the pid found via "ps -ef"). If you experience a problem displaying the data, you may also need to run each of the mainScript.csh commands with the "-clipSups" argument.
Execute 'grep -i nrcast $FXA_LOCALIZATION_ROOT/$FXA_INGEST_SITE/gridNetcdfKeys.txt' and use the key to set a purge limit in $FXA_CUSTOM_FILES/localPurgeInfo.txt. We recommend '|||1- | 12', but please realize that each hour of data (analysis plus six forecast times) will consume around 16 MB of disk space (actual bandwidth is much less), so please audit your disk with a 'df' command ahead of time. Perform a '-purge' localization on dx1 and dx2, then restart the purgeProcess on dx1.
As fxa on dx1, restart the notificationServer to complete.
Restart D-2D on the lx/na workstations to access the new products in the volume browser.
If problems arise — You may need to run dos2unix on some scripts and files.
Support for NWS/NCEP Centers
To obtain the Convective Development Nearcasting Model for N-AWIPS/GEMPAK, use the following configuration files as templates:
- For the LDM, including gddiag script, projection file, and sample pqact.conf (ld.tgz)
- For N-AWIPS, restore files for viewing output and layer differences in nmap2 (re.tgz)
- Additional sample files: config/datatype.tbl, nmap/mod_res.tbl
Thanks to Jason Levit at AWC for his assistance in developing the store_NRCAST_nagb2.sh file.
