GOES stands for Geostationary Operational Environmental Satellites. These are satellites that orbit the Earth at a fixed position over the equator, providing continuous measurements of the atmosphere, land, and oceans over the Western Hemisphere. They are operated by NOAA (the National Oceanic and Atmospheric Administration) in collaboration with NASA (the National Aeronautics and Space Administration).
GOES data has many benefits for weather forecasting, climate monitoring, and space weather research. Some of these benefits are:
Improved hurricane track and intensity forecasts
Better detection and observation of severe storms, tornadoes, wildfires, fog, dust storms, volcanic eruptions, etc.
More accurate and timely information on atmospheric conditions and solar activity
Enhanced monitoring of environmental phenomena that affect public safety, health, and economy
How to access GOES data?
There are many sources and platforms that offer GOES data in different formats and resolutions. Some of these are:
: This website provides imagery at a glance for various regions and products from the GOES satellites.
: This website provides magnetic field, energetic particle, soft X-ray, solar X-ray imager, EUV sensor data from the GOES satellites.
: This website provides gridded satellite (GridSat) GOES/CONUS (Continental United States) data that were created to make it easier to use GOES data.
: This website provides space weather data from the latest generation of GOES satellites (GOES-16/17/18).
: This document provides an overview of the GOES-R series satellites (GOES-16/17/ 18) and the data products they offer.
Data formats are the ways that data are stored and organized. Different data formats have different characteristics and advantages depending on the purpose and application of the data. Some of the data formats available for GOES data are:
GVAR: This is the raw data format that is transmitted from the GOES satellites to the ground stations. It contains all the information from the satellite sensors, but it is not easy to use or interpret without specialized software and hardware.
AREA: This is a compressed data format that is derived from GVAR. It contains only a subset of the information from GVAR, but it is more user-friendly and compatible with various software and applications.
NetCDF: This is a self-describing, machine-independent data format that supports the creation, access, and sharing of array-oriented scientific data. It is widely used in the scientific community and can store metadata along with the data values.
GIF: This is a common image format that can display up to 256 colors. It is suitable for simple graphics and animations, but it does not support transparency or lossless compression.
JPEG: This is another common image format that can display millions of colors. It is suitable for complex graphics and photographs, but it uses lossy compression, which means some quality is sacrificed for smaller file size.
