33 Version 1.0, 30 November 2004 Slide: 33 Detection of Contrails HRV: straight white lines (if no low-level clouds) or dark lines (shadow on lower clouds) IR IR10.8: dark lines RGB HRV/HRV/IR12.0-IR10.8: straight yellow lines over blueish clear ground RGB IR12.0-IR10.8 / IR10.8-IR8.7 / IR10.8: dark blue lines Large contrails can be detected in VIS, IR and WV channels, and also in differences like IR3.9-IR10.8 and IR8.7-IR10.8, but they appear most clearly in: Contrails can be best observed from MSG in the early morning or late afternoon in the visible channels (low sun angle and shadows help)
