METAR code messages with examples

Format options 6 through 8 are similar to options 3 through 5, except they include a METAR code (see Present weather codes produced by the CS125). The following are examples of the format outputs. Refer to Campbell Scientific output message field descriptions for details about the fields.

Example basic METAR format output (visibility units = meters, no significant weather [NWS]):
