Hi, Amelia —
<div>Always use ‘open’ with GDS station data URLs.</div>
<div><br>
</div>
<div>Once you’ve got the data set open, you can’t explicitly set which stations will get plotted on a lat/lon map. The only option is to use the ‘filt’ variable to control the density of stations in the domain. </div>
<div><br>
</div>
<div>'open <a href="http://monsoondata.org:9090/dods/stn/metar/2016/mon02'">http://monsoondata.org:9090/dods/stn/metar/2016/mon02'</a></div>
<div>‘set lon 6 20’</div>
<div>‘set lat 36 48’</div>
<div>‘set stid on’</div>
<div>‘set digsiz 0.15’</div>
<div>‘set gxout stnmark’</div>
<div>‘d ts’</div>
<div><br>
</div>
<div>You will see a map that shows all the stations reporting surface temperature with the stationID printed below the colored marks. you can use ‘filt’ to thin out the reports, e.g. </div>
<div><br>
</div>
<div>
<div>'d maskout(ts,4-filt)’</div>
</div>
<div><br>
</div>
<div>This will show fewer reports. To see what the ‘filt' value is for each station, </div>
<div><br>
</div>
<div>‘set gxout value’</div>
<div>‘set digsiz 0.1'</div>
<div>‘d filt’</div>
<div><br>
</div>
<div>If you also ‘set stnprint on’ and ‘set stat on’, GrADS will print the stationID, lon, lat, lev, and value to the terminal (or to the ‘result’ variable if you are running in a script).</div>
<div><br>

<br>
the February Metars , my goal is to extract some Metar Airports at <br>
specific time and plot them on a map.<br>
<br>
I don't kow how to procede. I tried open <br>
