Dear sir
I hope you are fine. i could solve the earlier problem send to you. i am
using the program anal2.f to read the different variables of the file
anal.1998040100.288 .from GAME reanalysis site. sp, slp i could read
correctly and plot in grads. i
am having problem with the u, v,z variables. i can read the data for u,v
wind in binary form and wrote ctl file to plot them. in grads the contours
are coming from 300 to 1000 interval 100. but when i am using the
origininal ctl file anal_125.ctl given in GAME site and plotting u,v, the
values are coming from -20 to 20, -30 to 30.
also i could not set the level.
when i am giving set lev 500
d u
i am getting contours from 300 to 1000,
the same is for all the levels.
kindly help me out
with regards
arpita
