APP4 bug fixed

Under the subroutines, the app_functions.py needs to be updated with the following suggestion:

subroutines/app_functions.py


# 20122023: ars599 replace the interpolate code lat and lat_v should swap
def plevinterp(var,pmod,heavy,lat,lat_v):
    plev,bounds=plev19()
    t,z,x,y=np.shape(var)
    th,zh,xh,yh=np.shape(heavy)
    if xh != x:
        print 'heavyside not on same grid as variable; interpolating...'
        hout=np.ma.zeros([th,zh,len(lat),yh],dtype=np.float32)
        for k in range(th):
            for i in range(zh):
                for j in range(yh):
                    hint=interp1d(lat_v,heavy[k,i,:,j],kind="linear",fill_value="extrapolate")
                    hout[k,i,:,j]=hint(lat)
    hout=np.where(hout<=0.5,0,hout)
    hout=np.where(hout>0.5,1,hout)
    vout=np.ma.zeros([t,len(plev),x,y],dtype=np.float32)
    print 'interpolating var from model levels to plev19...'
    for k in range(t):
        for i in range(x):
            for j in range(y):
                vint=interp1d(pmod[k,:,i,j],var[k,:,i,j],kind="linear",fill_value="extrapolate")
                vout[k,:,i,j]=vint(plev)
    return vout/hout

Probably best to make an issue for this on the repo @ars599
