Description: | The brightness temperatures and retrieved PWV and LWP show a sudden jump and have values that are too high. The suddenly jump back to normal at around 1800 UTC. All other parameters seem reasonable so the cause of the jump may just be due to accumulation of either snow or melting ice on the radome. |
