How to get the environment（L）with the shape of 32 * 32 * 3

Recently I read the supplementary material of iclight ， and I notice that the dataset contains an environment L with the shape of 32 * 32 * 3，maybe it is a convolution from HDR（like the process of switchlight），how to get this Environment L？Can you supply the relevant code， sincerely hope that you can help me with this question.
