+# 124
+
+124, also known as *Cloud RGB*, is an enhancement designed to make clouds stand out more compared to surface features, while keeping the color scheme close to nature and easy to understand even for the general public.
+
+The name 124 comes from the usage of AVHRR channel 1 (0.862 µm) in the red position, channel 2 (0.63 µm) in the green position, and infrared channel 4 (10.8 µm) in the blue position.
+
+### Appearance
+
+Land appears green-bluish tinge (vegetated areas) or green-yellowish tinge (deserts), while sea appears dark purple black. 
+Snow and ice appear pale yellow, with melting snow having a more reddish tone
+Mid and low level clouds appear yellow. Thick high level clouds appear white. Thin high-level clouds appear bluish. 
+
+### Intended usage
+
+Meteorology (cloud detection and characterization at daytime).
+
+### Limitations
+
+Low level clouds, medium level clouds and snow have similar colors.
+Low contrast between vegetated and desert areas.
+Vegetation information is dependent on temperature.

 3b45, also known as *Alternate false color infrared*, is a basic infrared enhancement for night time use. Compared to 543b, it swaps the 12 µm and 3.75 µm channels, providing a different appearance.
 
+On METEOR-M, the enhancement is called 456 due to the different channel numbering.
+
 ### Appearance
 
 Land appears in various shades of orange-gray, where more orange tinged colors indicate lower surface temperature.

+# BD
+
+This enhancement, also called *Hurricane enhancement*, uses a look-up table to highlight certain temperatures in the eye and eye wall of the storm that are known to be related to the intensity of the storm.
+
+Dvorak (1984) developed a technique for measuring the intensity of these tropical cyclones by comparing the warmest spot within the eye and the warmest cloud top temperature within the cold cloud ring surrounding the eye. The greater that difference, the more intense the tropical cyclone.
+
+![Dvorak](descriptions/img/Dvorak.png)
