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.

### HDF5 Data Store

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
