This diagram image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Water infrared absorption coefficient large.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

Summary

Description
English: Water absorption spectrum. Absorption coefficient for water - liquid (red line), vapor (green) and ice (blue) between 667 nm and 200 μm (red and most important part of infrared).
