Column guide

Low Clouds (CL) Clouds below ~2 km. The most problematic for eclipse viewing — thick low cloud completely blocks the Sun. Source=ICON
Mid Clouds (CM) Clouds between ~2 km and 6 km. Can thin or thicken during the day; mid-level cloud often diffuses sunlight rather than blocking it entirely. Source=ICON
High Clouds (CH) Thin ice-crystal clouds above ~6 km (cirrus). Usually semi-transparent; they reduce contrast and corona visibility but rarely prevent naked-eye totality. Source=ICON
Total Cloud Cover (CT) The combined fraction of sky covered by all cloud layers. A quick single-number summary: 0 % = clear sky, 100 % = overcast. Source=ICON
Atmospheric Instability (CAPE) Convective Available Potential Energy — a measure of thunderstorm potential. High values (red/orange) mean a risk of afternoon convective clouds or storms. Source=ICON @14:00 since jul 3rd
Convective Rain Precipitation from showers and thunderstorms during the day. Even isolated convective cells near the eclipse path can cause last-minute obstruction. Source=ICON
Line of Sight A composite clarity index combining low, mid and high cloud fractions into one view of the sun at the altitude of the eclipse. Transparent = clear view of the Sun; dark = obstructed. Source=Besselian Elements Team
Satellite Image True-colour EUMETSAT MSG satellite image captured around 18:00 UTC — the actual cloud situation as seen from space on that day. Source=EUMETSAT
Convection Sat. (RGB) EUMETSAT RGB Convection product at 14:00 UTC — colour-coded to highlight deep convective cells (orange), growing cumulus (yellow), thin cirrus (white) and warm/dry surfaces (blue). Checked before eclipse time to anticipate storm development. Source=EUMETSAT
