[ncl-talk] Fw: Skew-T

[Dennis Shea]

Not sure what to say.

[1] To my knowledge, no one has written a function to decode a SYNOP
message.

[2] asciiread and  parsing sequences (checking for spaces,  / and =  etc)
is tedious programming.

Maybe someone in the NCL world has their own script thay could share.

Sorry
