| Subject: | SGP/CEIL/B4 - Window contamination |
| DataStreams: | sgpceilB4.b1 |
| Description: | During this period, the VCEIL window repeatedly became contaminated by bird droppings shortly after each cleaning. Detection of clouds was intermittently limited. The window warnings are contained in the status_flag data. The cleaning frequency was increased and then bird deterrent spikes were installed on 3/24/2009. Cloud height measurements are suspect when the status_string field contains the "Window contaminated" warning. |
