GOES 16/17

The GOES-R decoder supports the ingest and display of NOAAport products (currently on the NIMAGE feed), Derived products (Level 2b netCDF files), and the Geostationary Lightning Mapper (GLM) products.

GOES-R products are accessible in the Satellite menu. The menu is broken into sections and has submenus for each of the separate geospatial products: CONUS, Full Disk, Mesoscale Sectors, Hawaii, Alaska, and Puerto Rico. Each submenu has products for individual channels and RGB Composites, as well as submenus for channel differences and derived products. GLM data can also be found with its own submenu option a little lower down the menu and under the Surface menu.

NOTE: The RGB products are not available on MacOS.

LDM Pattern Actions

This is found in the LDM's pqact.conf file which is located in /awips2/ldm/etc. The entries for GOES data are shown below. There are three different feeds that supply the individual channel data, derived products, and GLM data: NIMAGE, HDS and DIFAX, respectively.

Individual Channels

All geospatial sectors have individual channel products that can be viewed. Below are samples of Channel 02 (0.64μm) for each of the sectors. These products come through the NIMAGE feed in the LDM.

CONUS 1km

Full Disk 6km

Mesoscale Sectors (TMESO-1, TMESO-2)

Two floating mesoscale sectors (will vary from image shown)

Puerto Rico (PRREGI)

Alaska

Hawaii

RGB Composites

RGB Composites are also available for each sector. The three RGB products are: Icing - Ch 5, 3, 2 (1.61μm, 0.87μm, 0.64μm), Composite - Ch 2, 5, 14 #1 (0.64μm, 1.61μm, 11.20μm) and Composite #5 - Ch 2, 3, 2 (0.64μm, 0.87μm, 0.64μm). These products are generated on the fly in AWIPS using the existing channel products from EDEX.

!!! warning "GOES RGB Imagery is NOT SUPPORTED on macOS"

OpenGL Shading Language limitations prevent multi-channel imagery from displaying correctly on Mac.  Please use the Linux or Windows installs to view RGB products.

Channel Differences

Channel differences are the result of subtracting one channel from another to produce a new product. These products are generated on the fly in AWIPS using the existing channel products from EDEX.

NOTE: These may not be available for all sectors.

There currently 10 channel differences that are offered in CAVE:

• Split Window (10.3 - 12.3 μm)
• Split Cloud Top Phase (11.2 - 8.4 μm)
• Night Fog (10.3 - 2.9 μm)
• Day Fog (3.9 - 10.3 μm)
• Split Fire (2.2 - 1.6 μm)
• Split Ozone (9.6 - 10.3 μm)
• Split Water Vapor (6.19 - 7.3 μm)
• Split Snow (1.6 - 0.64 μm)
• Vegetation (0.64 - 0.87 μm)
• Upper Level Info (11.2 - 6.19 μm)

NOTE: The rendering of these products uses the Jep package in Python, which has known to have issues installing on the MacOS and Windows versions.

Derived Products

Derived products are also known as Level 2+ products and are come through the HDS feed in the LDM. There are over 20 products currently available in AWIPS. To find out some more information on some of the products please the Quick Guides compiled by CIRA.

NOTE: These may not all be available for each sector.

The current products offered in CAVE are:

• Aerosol Detection

Geostationary Lightning Mapper (GLM)

NASA's SPoRT MSFC Earth Science Office has contributed plugins to decode GLM level2 products, displayed as point data in CAVE.

GLM data is located in the menu structure: Satellite > Geostationary Lightning Data (GLM). Data are displayable is available for Flash, Event, and Group products.

There is also additional GLM data available in the Surface > GLM - Geostationary Lightning Mapper submenus.
