A command-line implementation of the RAMMB/CIRA SLIDER tool in Golang. This tool downloads NOAA images taken by weather satellites in space and creates animations/GIFs from those images. See an example below.
SLIDER is the Satellite Loop Interactive Data Explorer in Real-time .
This tool is meant to replicate most of the features of SLIDER and includes some additional flexibility in configuration options. The goal of this utility is to resolve some common issues with the SLIDER web interface, specifically:
- Incomplete frames being rendered on screen
- Slow to generate animations
- Web browser may crash for complex animations
- Limited options for features like time-step and speed
This is not to downplay the awesomeness that is the SLIDER web UI. The folks who created it did amazing work and this CLI tool hopes to be complementary to that effort. For more details on their effort check out this 2018 talk from AMS on SLIDER.
This is not an official product of NWS, NOAA, RAMMB, or CIRA.
Platforms Supported: Windows, Linux, Mac
Head to the Releases
page to download the latest version. Or you can build the source code with
make build, which requires Golang and CMake.
./slider-cli --satellite=goes-16 --sector=conus --product=geocolor -z=2slider-cli version v0.3.0-2-g96b20c8-96b20c8 (Built 2021-04-09T23:45:32Z)
Usage:
--allow-stale Allow imagery more than a year old -- filtering these images
outhelps eliminate issues with loops containing old data.
--angle int Degrees to rotate the animation.
-b, --begin string Desired image capture time of the first image in the loop. Use the
timestamp format YYYYMMDDhhmmss. This flag cannot be used with --end.
--date-list Print a list of available dates
--decode string Decode a SLIDER URL into a loop config and create an animation. You
must supply --time-step as well as that can't be decoded from the URL.
-d, --dir string Output filename to save rendered animation in. (default ".")
-e, --end string Desired image capture time of the last image in the loop. Use the
timestamp format YYYYMMDDhhmmss. This flag cannot be used with --begin.
--help Print help dialog.
-i, --image-count int Number of images in the loop. (default 6)
-l, --loop string Loop style. Options are 'forward', 'reverse', or 'rock'. Note that
using 'rock' will nearly double the output animation file size.
(default "forward")
-o, --output string Output filename to save rendered animation in. (default auto-generated)
-p, --product string Satellite product to request imagery for. See --product-list for
the full list. (Example: geocolor)
--product-list Print a list of available satellite products
-s, --satellite string Satellite to request imagery for. See --satellite-list for the full
list. (Example: goes-17)
--satellite-list Print a list of available satellites
-c, --sector string Satellite sector to request imagery for. See --sector-list for the
full list. (Example: conus)
--sector-list Print a list of available satellite sectors
--speed int Desired frame rate in 100ths of a second. The lowest value accepted
is 1. (default 15)
-t, --time-step int Desired interval of image capture times in minutes. (default 5)
-v, --verbose Enable verbose output.
-V, --version Print version and exit.
-z, --zoom int Zoom level (changes resolution). See --zoom-list for the full list
of allowed zoom levels. (default 1)
--zoom-list Print a list of available zoom levels for satellite sectors

- The 10000x6000px images for GOES Bands 1, 2, 3, & 5 are missing because I don't know of a good source for them without the map overlays already included. If anyone knows where to find these images please open a GitHub issue and let me know.
- At this time you can only specify a begin timestamp or an end timestamp but not both at the same time. In the future I want to be able to support that feature as an alternative to specifying an image count.
