*NOTE: Some 2B-GEOPROF-LIDAR files have periods with no Arctic data. I have manually removed these *bad* data granules from the analysis during summer and early fall. As a result, the RL maps have different temporal sampling than the radar-only maps during these periods. I have not done a thorough investigation of this issue outside of the Arctic, so use these maps with some caution.
