Mission: MODIS calibration mission.

Mission Objectives

Underfly Terra for MODIS LWIR calibration validation.

Flight Summary

Take-off was at 1438 UTC. ER-2 landed at 1725 UTC.

ER-2 flew from MSN to OSH on climb out and then went to NE waypoint of the Lake Huron racetrack parallel to the Terra suborbital track line and flew towards SW on the line and then turned to a parallel (19 nm separation) line to complete the racetrack.  Terra overpass at 1623 UTC.  Skies were mostly low cumuliform cloud in the scenes.  Met Terra near the end of the 2nd leg of the racetrack with clouds in the scene.  Because of cloud prevalence, after completing one orbit of the racetrack the ER-2 broke off and returned to Madison via OSH

Highlights
