A Week of Weather from NOAA's GOES West: Air Mass and Water Vapor Revealed

This week, we're taking a deep dive into the fascinating world of atmospheric observation with a full week's worth of data from NOAA's GOES West satellite. The provided imagery showcases the power of advanced satellite sensors in revealing the intricate details of our planet's weather systems, specifically through Air Mass RGB and Water Vapor composite images.

Unveiling Atmospheric Dynamics

The Air Mass RGB (Red, Green, Blue) composite is a valuable tool for meteorologists, allowing them to visualize different layers of the atmosphere and identify features like moisture content and cloud top temperatures. Similarly, Water Vapor imagery highlights the distribution of moisture in the atmosphere, crucial for tracking storms and understanding weather patterns.

Accessing and Utilizing This Data

For those interested in replicating or expanding upon this kind of analysis, the data is readily available. NOAA provides a wealth of information through their National Environmental Satellite, Data, and Information Service (NESDIS). You can access full disk images from GOES West (also known as GOES 18) at:

These links offer images at impressive resolutions, including up to 21696 x 21696 pixels. To download a week's worth of files, you'll need to match the start day number with a 'for loop' and iterate through files. The provided Go code at can assist in this process.

Important Note: When working with this data, be mindful of the potential download size. It's advisable to start with smaller resolution images, such as the 678 x 678 px versions available at , to get a feel for the data before downloading larger files.

This type of data is invaluable for researchers studying atmospheric phenomena, from the formation of eddies to the global distribution of water vapor. It's a testament to the ongoing advancements in space technology and our ability to monitor and understand our planet.
