🖼️ GeoColor

1. Daytime: Combines red, blue, and a synthetic green band to simulate true-color imagery — looks like a photo from space 🌍
2. Nighttime: Switches to infrared bands to show cloud types
   • Blue = low liquid clouds (fog, stratus)
   • White/Gray = high ice clouds
   • City lights = static overlay from VIIRS for orientation 🌃

🌞 Visible Imagery

• Captures reflected sunlight — only works during the day ☀️
• Bright white = thick clouds (like cumulonimbus)
• Grayish = thin clouds or snow
• Dark = oceans, lakes, or land with low reflectivity
• Best for: Spotting developing storms, fog, and cloud structure in real time4

🌡️ Infrared (IR) Imagery

• Measures heat radiation — works day and night 🌙
• Bright white = cold cloud tops (high altitude)
• Dark gray/black = warmer surfaces or low clouds
• Useful for:
  • Estimating storm intensity (cold tops = strong storms)
  • Tracking cloud height and nighttime weather5

💧 Water Vapor Imagery

• Detects moisture in the mid to upper atmosphere (15,000–30,000 ft)
• White/blue = high moisture
• Dark orange/brown = dry air
• Great for:
  • Spotting jet streams and upper-level disturbances
  • Identifying areas primed for heavy rain or storm development
  • Seeing air movement even when no clouds are present
