This chapter contains information that is needed to operate this product.
Vaisala Present Weather Detector PWD22/52 is a fully automatic
instrument for continuous weather measurement. Usually, PWD22/52 is
either set to send a data message automatically or it is polled by a host
computer. In addition, a set of user commands is provided for
configuring and monitoring the system performance. These commands
can be given in the command mode (see section Entering and Exiting the
Command Mode on page 49).
PWD22/52 has seven different standard message formats for data
message output. It presents the weather type using the World
Meteorological Organization (WMO) code table 4680 (WaWa, in other
words, Present Weather reported from an automatic weather station).
PWD22/52 reports present weather also in WMO code table 4678
(METAR) format. In addition, the United States National Weather
Service (NWS) abbreviations are available. The NWS list and WMO
codes is presented in Appendix C, NWS and WMO Code Tables, on
page 111.
