GOES-16 (GOES-R)

GOES-16 is now operational as GOES East, and products are available on Unidata's edex-cloud.unidata.ucar.edu server, including 16 channels of ABI imagery and various derived products.

The NASA Short-term Prediction Research and Transition (SPoRT) center has developed decoding and visualization plugins for global Geostationary Lightning Mapper (GLM) observations and Derived Wind Motion vectors, available in the latest Unidata CAVE release for Linux and macOS.

GOES East products are accessible in the Satellite menu:


RGB Composites

Multi-Channel Icing Composite

Channels 5,3,2 (1.61u, 0.87u, 0.64u)

Multi-Channel Daytime 1 Composite

Channels 2,5,14 (0.64u, 1.61u, 11.20u)

Multi-Channel Daytime 2 Composite

Channels 2,3,2 (0.64u, 0.87u, 0.64u)

GOES-16 Composite Imagery NOT SUPPORTED on macOS

OpenGL Shading Language limitations prevent multi-channel imagery from displaying correctly on Mac.


Derived Products

GLM

Derived Motion Winds

Puerto Rico sector (PRREGI)

CONUS 1km

Full Disk 6km

Mesoscale Sectors (TMESO-1, TMESO-2)

Two floating mesoscale sectors (will vary from image shown)

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:

drwxr-xr-x 18 awips fxalpha PRREGI
drwxr-xr-x 18 awips fxalpha TCONUS
drwxr-xr-x 18 awips fxalpha TFD
drwxr-xr-x 18 awips fxalpha TMESO-1
drwxr-xr-x 18 awips fxalpha TMESO-2

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 17.1.1 can support their ingest if made 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 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
