define standard longitude for lambert conformal projection

Hi,

Is there any way to set standard longitude value for lambert conformal projection. My current basemap parameters are,

m = Basemap(projection=‘lcc’,

lat_1=30.0,

lat_2=60.0,

lat_0=40.0,

lon_0=16.0,

llcrnrlon=-10.0,

llcrnrlat=25.0,

urcrnrlon=50.0,

urcrnrlat=50.0,

resolution=‘i’)

but i want to add standard longitude (32) as parameter to basemap.

Thanks,

Don't quite know what you mean by standard longitude, but I think it's probably lon_0 (which you have set to 16). I don't think it will have any effect though, since lon_0 just defines the origin of the coordinate system (which will be over-ridden by the corner latitude and longitude parameters that you specify). If you use the width and height keywords instead to define the projection region, then lon_0, lat_0 will be used to determine the center of the map.
