Retreive GOES-16/17 data from AWS. Also proves some RGB recipes.

Download and display GOES-East and GOES-West data

GOES-East and GOES-West satellite data are made available on Amazon Web Services through NOAA's Big Data Program. GOES-2-go is a python package that makes it easy to find and download the files you want to your local computer with some additional helpers to look at and understand the data.

Capabilities

Download Data

Download GOES ABI or GLM NetCDF files to your local computer. Files can also be read with xarray.

from goes2go.data import goes_latest, goes_nearesttime
# Get latest data
G_ABI = goes_latest(satellite='G16', product='ABI')
# Get data for a specific time
G_GLM = goes_nearesttime('2021-01-01 12:00', satellite='G16', product='GLM')

RGB Recipes

The rgb xarray accessor creates an RGB product for a GOES ABI multichannel xarray.Dataset. See the demo for more examples of RGB products.

from goes2go.data import goes_latest
import matplotlib.pyplot as plt
G = goes_latest()
ax = plt.subplot(projection=G.rgb.crs)
ax.imshow(G.rgb.TrueColor(), **G.rgb.imshow_kwargs)
ax.coastlines()

Field of View

The FOV xarray accessor creates shapely.Polygon objects for the ABI and GLM field of view. See notebooks for GLM and ABI field of view.

from goes2go.data import goes_latest
G = goes_latest()
# Get polygons of the full disk or ABI domain field of view.
G.FOV.full_disk
G.FOV.domain
# Get Cartopy coordinate reference system
G.FOV.crs

GOES-West is centered over -137 W and GOES-East is centered over -75 W. When GOES was being tested, it was in a "central" position, outlined in the dashed black line. Below is the ABI field of view for the full disk:

The GLM field of view is slightly smaller and limited by a bounding box. Below is the approximated GLM field of view:

What if I don't like the GOES-2-go or Python?

As an alternative you can use rclone to download GOES files from AWS. I quite like rclone. Here is a short rclone tutorial.

I hope you find this makes GOES data easier to retrieve and display. Enjoy!
