The Share of Observation Data of Three Meteorological Elements

For seismic instruments effected by the meteorological elements with d ifferent degrees,we often install the appropriate meteorological instrument in the stations according to the precursor instruments.Take the PTR-Ⅲ meteorologi cal instrument matching to the GPS observations as an example,this paper analyz es the share method of observation data of this instrument and WYY-1 of meteorol ogical instrument in "tenth-five-year"observation network..We compile the pro gram to download the WYY-1 data automatically and to convert them to the PTR-Ⅲ format,so as to reduce the number of the secondary observation instruments of s tations,and relieve the burden of instrument maintenance.
