Two examples demonstrating how filter conditions and parameters might be selected from command line instead of having to provide them in files:
bufrdump.pl syno_2010120206.bufr --station wmonr=01001,01492,06180 --param wmonr,TA,PO,NN
or shorter:
bufrdump.pl syno_2010120206.bufr -st wmonr=1,492,6180 -p wmonr,TA,PO,NN
wmonr=01001 TA=-5.8 PO=999.1 NN=8 wmonr=06180 TA=-2.9 PO=1015.2 NN=6 wmonr=01492 TA=-11.8 PO=1012.4 NN=0
bufrdump.pl syno_2010120206.bufr --filter 'TA < -10, wmonr > 02000, wmonr < 02800, NN = 0' --param wmonr,TA,PO
wmonr=02787 TA=-10.5 PO=998.5 wmonr=02769 TA=-16.2 PO=1010.2 wmonr=02324 TA=-20.1 wmonr=02378 TA=-16.3 PO=1020.6
