GOES-R Convective Initiation Nighttime Transition

The GOES-R Convective Initiation seems to have issues at nighttime. This even occurs with the use of infrared satellite data in the algorithm.

Here are a couple images from the transition from day to night:

From these images, it seems the convective initiation algorithm is probably more useful during the day. The coarser resolution of the infrared satellite data could possibly explain this problem.

- During the day, the CI algorithm utilizes information from both IR and visible satellite imagery. At night, the algorithm has no visible satellite data and must rely solely on the coarser IR imagery. This explains some of the changes in probabilities you might see in the transition from day to night - BL
