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. Since then, many other offices have used this data.
In addition, this data was 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 and 2011.
In addition to AWIPS, this data and a short archive is also available online:
Acquiring Data at a NWSFO
Data is currently available to Weather Forecast Offices in Central Region, Eastern Region, Pacific Region (HNL only), Southern Region, and Western Region. We are unable to supply this to Alaska Region at this time. Data is transmitted in compressed 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 preProcessCONVECT.pl and assign executable permissions
- preProcessCONVECT.pl for WRH WFOs and SRH WFOs serving New Mexico
- preProcessCONVECT.pl for WFO HNL Honolulu, HI
- 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)
- Append to pqact.conf
- 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
- Add convect.cdl to create the netCDF template
- conwest.cdl for WRH WFOs and SRH WFOs serving New Mexico - Updated 7/2011
- convecthi.cdl for WFO HNL Honolulu, HI
- Append to dataFieldTable.txt to add new fields
- Append to dataLevelTypeTable.txt to add new levels
- Append to gridImageStyle.rules to set the image display - Updated 6/2011
- Append to gridPlaneTable.txt to add new planes
- Append to iconStyle.rules to display the icons (assure density is set to "Max")
- Append to localGridSourceTable.txt to add the grid source
- localGridSourceTable.txt for WRH WFOs and SRH WFOs serving New Mexico
- localGridSourceTable.txt for WFO HNL Honolulu, HI
- Append to localImageStyle.txt to display the images/sampling values
- Modify virtualFieldTable.txt (position sensitive; new variables section) - Updated 6/2011
Optional — You may also wish to append "CONVECT" ("CONWEST" for West, or "CONVECTHI" for Pacific) to activeGridSources.txt
In $FXA_HOME/data as fxa on dx3 (runs Grib2Decoder):
- Modify grib2CodeTablesSect4.txt (position sensitive)
- Modify grib2Models.txt (position sensitive)
- grib2Models.txt for WRH WFOs and SRH WFOs serving New Mexico
OR instead of the above two modifications — You may wish to add or append to updateGridFiles.patch in $FXA_CUSTOM_FILES as fxa (Thanks to Josh Watson, ERH)
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 -tables -grids -dirs' on dx3 and dx4, then '$FXA_LOCALIZATION_SCRIPTS/mainScript.csh f -tables -grids' on all lx and na workstations. Restart Grib2Decoder when finished (kill the pid found via "ps -ef").
Execute 'grep -i convect $FXA_LOCALIZATION_ROOT/$FXA_INGEST_SITE/gridNetcdfKeys.txt' and use the key to set a purge limit in $FXA_CUSTOM_FILES/localPurgeInfo.txt. We recommend '|||1- | 24', but please realize that each hour of data will consume around 0.7 GB of disk space (actual bandwidth is much less), so please audit your disk with a 'df' command ahead of time. Perform a '-tables -grids -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 Initiation and Overshooting Top/Thermal Couplet algorithm output for N-AWIPS/GEMPAK, use the following configuration files as templates:
- Files for obtaining GEMPAK-formatted files via LDM and configuring N-AWIPS (ci2-config.zip)
- For nmap2, restore files for viewing output and probability products (ci2-restore.tgz)
