Generic SYNOP code messages with examples

Format options 9 through 11 are similar to options 6 through 8, except they include a generic SYNOP 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 generic SYNOP format output (visibility units = meters, no significant weather [NWS]):

9 0 0 20481 M 0 0 NSW 73DF

Example basic generic SYNOP fields¹
Message ID	Sensor ID	System Status	Visibility distance	Units	Generic SYNOP code	SYNOP code	METAR code	Checksum (CCITT)
9	0	0	20481	M	0	0	NSW	73DF
¹The messages start with STX (a hexadecimal command character) and end with ETX (a hexadecimal command character), carriage return, and a line feed. These values are not shown in this table.

Example partial generic SYNOP format output (12 s interval, visibility units = meters, NWS):

10 0 0 12 20909 M 0 0 0 0.00 0 0 NSW 24.2 -99 AB02

Example partial generic SYNOP fields¹
10	0	0	12	20909	M	0 0	0	0.00	0	0	NSW	24.2	–99²	BD78
¹ The messages start with STX (a hexadecimal command character) and end with ETX (a hexadecimal command character), carriage return, and a line feed. These values are not shown in this table. ²The –99 value is reported when a HygroVue temperature and relative humidity sensor is not connected to the CS125.
