Dear All,
I have an important doubt. I would like to get wind's field referenced at
earth coordinates. I have found a way to achieve this:
Uearth = U*cosalpha + V*sinalpha
Vearth = V*cosalpha - U*sinalpha.
, where:
sinalpha = wrf_user_getvar(a,"SINALPHA",0)
cosalpha = wrf_user_getvar(a,"COSALPHA",0)
u = wrf_user_getvar(a,"ua",-1) ; u at mass point
v = wrf_user_getvar(a,"va",-1) ; v at mass point
But I see, there are another way to do this. Using this function:
uvm = wrf_user_getvar(a,"uvmet",-1)
The problem is uvm(0, , , , ) {component u} isn't the same than Uearth.
I don't know what is the problem.
Could you help me, please?
Best Regards,
Diego
