Θ vs along-track view angle (band = cross-track spread)

AirHARP FOV: ±57° along-track × ±47° cross-track (published spec). Θ = 180° is exact backscatter (glory). Green band / bright footprint = cloud-retrieval range (130–165°); footprint pixels outside it are dimmed. Sun arrow shown in yellow.

Θ seen at the selected ground pixel across the aircraft overpass: x = along-track viewing angle (−57° aft … +57° fore), accounting for the time it takes the aircraft to fly the pass. Dots = selected band's view sectors. Click inside the footprint to pick a pixel; click elsewhere to move along the route.

Θ along the whole route

Min–max Θ available at each point of the flight for the current start time / speed / altitude / band. Click to jump. Gaps = sun below horizon.

🎯 Tip: click anywhere inside the footprint to show the multi-angle (hyper-angular) scattering angle data for that pixel.
