Hi, re: > Your email didn't have a message. I was attempting to move your inquiry from the NOAAPport department to the IDD department, and what I tried didn't work as planned. re: > Just to add, I read on the NOAA website the following, > which matches with the date of our outage.

It appears that you were not subscribed to any of the lists that the message was sent to, so I advise you to subscribe to one or more of the following so that you will get notices like this in the future: address@hidden address@hidden, address@hidden address@hidden address@hidden address@hidden re: > "Please Note: > > Update 3/2/2020: GOES-15 supplemental operations ended on March 2, 2020.

Yup, GOES-15 was turned off on March 2. re: > MCIDAS ^pnga2area Q. (U[^ACXY1]) (.*) (.*)_IMG (0.65)um (.*) (........) > (....)

In the message is the URL for the web page that shows the list of products being sent in the UNIWISC (aka MCIDAS) IDD feed now, and that page has links to an example pattern-action file actions to process the images. Date: Tue, 18 Feb 2020 16:19:05 -0700 Message-Id: <address@hidden> 2nd Notice: Users of the IDD UNIWISC (aka MCIDAS) data feed: We will be upgrading the Unidata-Wisconsin IDD data stream (IDD feedtype UNIWISC (aka MCIDAS)) with products that use GOES-17 imagery in replacement of GOES-15 imagery and with updated GOES-East and GOES-West imagery products tomorrow, Wednesday, February 19, 2020. Why: NOAA has announced the cessation of GOES-15 operations on March 2, so those products that currently use/incorporate GOES-15 imagery will need to be replaced/updated. Here is a snippet from the NOAA announcement describing the GOES-15 status change: January 29, 2020 "GOES-15 supplemental operations to GOES-17 will be extended to March 2, 2020. After that date, the GOES-15 spacecraft will be placed in standby. GOES-17 will continue operating in the GOES-West role at 137.2 degrees west with all instruments operating nominally." A major implication of the cessation of GOES-15 operations is that the GINI imagery that is currently being distributed by the NWS in NOAAPort will no longer be available in NOAAPort or via an IDD feed. When: We are planning to add new/updated content to the UNIWISC data stream starting on Wednesday, February 19, 2020. We will continue to distribute UNIWISC content that contains/is based on GOES-15 imagery for as long as GOES-15 remains operational. Impacts of the changes being made to UNIWISC: The volume of data available in the UNIWISC feed will increase from an average of approximately 95 MB/hr to an average that is approximately 810 MB/hr, an 8.5-fold increase! The new products that will be available in the revamped UNIWISC feed are: - full spatial and temporal resolutions for GOES-East (GOES-16) and West (GOES-17) CONUS coverage for the 6.2um WV and 10.3um thermal IR channels, and a reduced resolution for the 0.64um VIS channels GOES-East/West 0.64um CONUS VIS imagery will have (nominal) resolutions of 1.0km and the 6.2um WV and 10.3um thermal IR imagery will have (nominal) resolutions of 2km. GOES-East CONUS channels will be remapped into the same TANC projection that is used for the national composite Level III radar products that are distributed in the IDD FNEXRAD feed. GOES-West CONUS channels will be distributed in the GOES-R fixed grid projection. GOES-East/West CONUS imagery will be available every 5 minutes when the satellites are scanning in modes 3 or 6, and will not be available when the satellites are operating in scanning mode 4. - full spatial and temporal resolutions for all mesoscale image coverages for the 0.64um VIS, 6.2um WV, and 10.3um thermal IR channels The mesoscale images are small in size, but they are numerous since the are available either every minute or every 30 seconds. GOES-East/West mesoscale 0.64um VIS images have (nominal) resolutions of 0.5km and the 6.2um WV and 10.3um thermal IR images have (nominal) resolutions of 2km. All mesoscale images are in the GOES-R fixed grid projection. - full temporal and reduced spatial resolutions for GOES-East/West full disk image coverages for the 0.64um VIS, 6.2um WV, and 10.3um thermal IR channels All full disk images will have (nominal) resolutions of 4km, and will be available every 10 minutes when the satellite producing the coverage is operating in scanning mode 6, every 15 minutes when the satellite is operating in scanning mode 3, or every 5 minutes when the satellite is operating in scanning mode 4. All full disk images will be in the GOES-R fixed grid projection. - GOES-East/West composite imagery for the 0.64um VIS, 6.2um WV, and 10.3um thermal IR channels The new East/West composite images will have (nominal) 4km resolutions and will be available either every 10 minutes when GOES-East is operating in scanning mode 6, every 15 minutes when GOES-East is operating in scanning mode 3, or every 5 minutes when GOES-East is operating in scanning mode 4. All East/West composite images will be in the GOES-R fixed grid projection centered on 105W longitude. - GOES-East Level 2 products: CAPE (CONUS coverage) Cloud Top Pressure (CONUS coverage) Lifted Index (CONUS coverage) Total Precipitable Water (CONUS coverage) Rain Rate QPE (full disk coverage) Sea Surface Temperature (full disk coverage) The update frequencies for these Level 2 products are dependent on the product type. Please refer to the following web page details: https://www.unidata.ucar.edu/data/uniwisc.html All GOES-East Level 2 products will be in the GOES-R fixed grid projection. - the other products already in the UNIWISC feed remain unchanged: Arctic multi-satellite composites (VIS, IRS, WV, IR, IRL) Antarctic mult-satellite composites (VIS, IRS, WV, IR, IRL) Global multi-satellite WV and IR composites in rectilinear projection Global multi-satellite WV and IR composites in Mollweide projection - sites wishing to use the new/revamped imagery that are being added to the UNIWISC feed must insure that they REQUEST the new data in their LDM configuration file REQUEST line(s), and update LDM pattern-action file actions to correctly process the imagery It is our observation that the most typical LDM configuration file REQUEST being used is for everything from the UNIWISC feed. For example: REQUEST UNIWISC ".*" <upsteam feed host> No action is needed for sites using this type of REQUEST, but users should be aware of the greatly increased data volumes that will result! Sites that would like to tailor their UNIWISC REQUEST(s) are advised to contact Unidata User Support <address@hidden> if they need guidance. - new processing action(s) will be need for the new imagery The LDM/IDD Product IDs for the great majority of the products in the revamped UNIWISC feed will change. The web page: https://www.unidata.ucar.edu/data/uniwisc.html contains detailed information on the image products that will be available in the revamped UNIWISC feed with example LDM/IDD Product IDs. This web page also has links to example LDM pattern-action file actions needed to process the new/revamped and existing images. For comparison, the web page: https://www.unidata.ucar.edu/data/uniwisc_old.html contains information on the products that have been distributed in the UNIWISC feed for the past decade or so. - all users are advised to update their display and analysis software to the latest version(s) that is(are) available from Unidata NB: this is especially true for GEMPAK users as only the most recent release of Unidata GEMPAK contains support for the GOES-R fixed grid projection that is used for the majority of the images in the revamped feed.
