Sanchez Scripting Examples For Post-Processing GOES, GK2A, Himawari, Elektro Satellite Images


Recently we posted about new updates to the Sanchez software. The updates allow users to combine images received from multiple geostationary weather satellites such as GOES 16/17, Himawari-8, GK-2A and Electro. The images can also be reprojected into a flat equirectangular image, and then optionally reprojected back into a disk view at any location on earth. Sanchez’s original function is also still there which allows users to add a false color underlay image to grayscale infrared images received from the satellites.

Sanchez is a command line tool, so scripts are required to do anything interesting. Over on his page Carl Reinemann has uploaded a page with a number of Sanchez command line examples available. The page shows examples like how to stitch together multiple images, and how to create a stitched time lapse animation. The YouTube video below shows an example of an animation Carl created with Sanchez and GOES 16 and 17 images stitched together.

And the image below is an example of an image of Himawari 8, GOES 16 and 17 he stitched together with Sanchez.
