Awaiting a moderator. See above.

# Requirement Summary

This proposal was presented at several past CF workshops during the course of 
its development. It has also been vetted by a number of subject matter experts. 
Given that it does not require any change of the data model or the conventions 
current text, it probably would fit best as a new appendix, similar to the 
current Appendix H for Discrete Sampling Geometries.

# Technical Proposal Summary

Earth Science swath data originates as electromagnetic radiation collected from 
a specific direction into a solid angle and then measured at a number of 
electromagnetic spectrum intervals. The combination of the direction, the solid 
angle, and the instrument data acquisition settings defines one observation. At 
any given instant an instrument sweeps over an area of the Earth while its 
platform (an object carrying such instrument) moves. Successive observations 
are usually combined to cover a larger portion of the Earth. When these 
successive observations are plotted on maps they appear to cover a swath on the 
Earth’s surface, hence the name for this type of data. The proposed encodings 
are independent from the observation method and are applicable to swath data 
acquired by instruments on either satellites, airplanes, or unmanned aerial 
vehicles (UAV).

# Benefits

All providers and users of remotely sensed geoscience data from satellites, 
airplanes, or UAVs.

# Status Quo

Swath data remains unsupported by the CF conventions.

# Detailed Proposal

The proposal is at 
https://github.com/Unidata/EC-netCDF-CF/blob/master/swath/swath.adoc. The new 
text for the conventions document will be based on the content in Sections 2.3 
through 2.6.
