Transform a rotated stretched longitude and latitude grid to regular two dimensional grid

Hi, I have a GCM output where the the precipitation values are stored in rotated stretched longitude and latitude with the following attributes:

coordinates:  lon lat
grid_mapping:  rotated_stretched_latitude_longitude
rotated_north_pole_latitude: 40. 
rotated_north_pole_longitude: 12.
stretching_coefficient:  2.5

Could someone offer me an approach which I should transform this grid mapping to regular two dimensional grid with?

Does rotatem do what you need? I'm not familiar with stretching coefficients.
