The GOES-R decoder supports the ingest and display of NOAAport provisional products (currently on the NOTHER feed), as well as Level 2b netCDF files. A GOES-R Geostationary Lightning Mapper (GLM) decoder is also provided to handle sensor lightning observations.
|
|
|
|
GOES-R products are accessible in the menu **Satellite** > **GOES-16 Provisional Products**

!!! warning "GOES-16 Composite Imagery NOT SUPPORTED on macOS"
|
|
|
|
OpenGL Shading Language limitations prevent multi-channel imagery from displaying correctly on Mac:
|
|
|
|
* Icing (1.61, 0.87, 0.64)
|
|
* Daytime Composite (0.64, 1.61, 11.20)
|
|
* Daytime Composite (0.64, 0.87, 0.64)
|
|
|
|
To display multi-channel composites requires CAVE for Linux or Windows.
|

|
Decoded GOES-R satellite images are stored in `/awips2/edex/data/hdf5/satellite/` under sector subdirectories:

## Level 2+ Products
|
|
|
|
Level 2+ products are described as derived environmental variables which will be created and disseminated when GOES-16 is used operationally (compared to **Level 0**, described as unprocessed instrument data at full resolution, and **Level 1b** products, described as radiometric and geometric correction applied to produce parameters in physical units).
|
|
|
|
Unidata does not currently have access to these products, but EDEX can support their ingest if a feed is available.
|
|
|
|

## 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.
|
|
|
|
While Unidata is not currently distributing GLM products, you can [download a sample netCDF file](https://www.unidata.ucar.edu/software/awips2/OR_GLM-L2-LCFA_G16_s20170402339144_e20170402339307_c20170402339509.nc) and copy it to `/awips2/data_store/ingest/` in order to test the decoding and display of GOES-R lightning data.
|
|
|
|
### Ingest Sample Data
|
|
|
|
Run the single command from your EDEX server to ingest a single-time sample data set:
|
|
|
|
wget https://www.unidata.ucar.edu/software/awips2/OR_GLM-L2-LCFA_G16_s20170402339144.nc -P /awips2/data_store/ingest/
|
|
|
|
|
|
### Display GLM Lightning Data
|
|
|
|
Load GLM data from the menu **Satellite** > **GOES-16 Provisional** > **GLM-Lightning**. Data are displayable as **Flash**, **Event**, and **Group** and 1min, 5min, 15min, and 1hr intervals.

|
## Derived Motion Winds
|
|
|
|
At the bottom of the menu **Satellite** > **GOES-16 Provisional Products** are sub-menus for GOES-16 Derived Motion Wind (DMW) products. Select the sub-menu **GOES-Test** and then region (CONUS, Full Disk, Mesoscale), and then select the wind product by level:
|
|
|
|
* By Pressure
|
|
* By Mandatory Levels
|
|
* By Channel
|
