You can easily use any metric for verification of your nowcasts:
# import the specific metric from the rainymotion library
from rainymotion.metrics import CSI
# read your observations and simulations
obs = np.load("/path/to/observations")
sim = np.load("/path/to/simulations")
# calculate the corresponding metric
csi = CSI(obs, sim, threshold=1.0)
