The satellite's powerful imagery will help forecasters track storms, hurricanes, wildfires and more as they move across the globe. The GOES-East satellite officially reached its weather-monitoring position in orbit in December, where it views the entire Western Hemisphere from a high geostationary orbit - it stays still relative to the Earth's surface as it orbits and the world turns. "Notice the long line of clouds stretching over a thousand miles south of the storm, which is drawing moisture all the way from deep in the Caribbean." See LICENSE file for details."The powerful nor'easter is battering coastal areas with heavy snow and strong winds, from Florida to Maine," NASA officials wrote in an image description.

The script will skip existing files during downloading and cropping. ImageJ is a useful tool for adjusting the crop defaults. 
Open geoSatView.R to edit further from defaults as needed. The script can also be run from an empty directory, as long as you set that directory as R's working directory. The script is also a useful reference for those looking to manipulate images in R and create videos. Vector, options: Binary: 1 = create AVI video, 0 = do not create video, 2 = create using ffmpeg system call (fastest)īelow is an example output. List(), format: c(NOAA="PATH_TO_NOAA_DATA",zoomEarth="PATH_TO_zoomEarth_DATA")Ĭhar vector, options: "NOAA", "zoomEarth". Downloading is parallelized, so output will be stored in progress.log in root directory. Videos are stored in the data_noaa or data_zoom_earth sub-directories that are created. Users can choose between NOAA or zoom.earth sources to create the video. Alternatively, users can download files to a separate folder by making that folder the active working directory then running source('path/to/geoSatView.R') geoSatView(). Make the working directory in R the repository root directory and type the below. Either download a zip of the repository or make a new folder and clone with git clone. 
The script requires ffmpeg be installed on users systems if Usage Then saves out a video file (default mp4) to video folder.Downloads a screenshot at 5 min intervals of the zoom.earth website centered on the West Coast of the United States.For Zoom Earth (which includes fire locations) data:.
Combines the cropped images and associated timestamps into a single image and saves to data_crop folder. Crops the image (default is focused on California and the Bay Area). Downloads GOES (GEOS-16 or GEOS-17 currently) satellite data ( ) into data folder. This script performs the following actions: GeoSatView Downloads GOES (GEOS-16 or GEOS-17 currently) or Zoom Earth satellite data and makes video animation using R.
