Mission: Umanaq B (priority:high)
This mission is designed (along with Umanaq A) to refly the 2012 Umanaq coast-parallel grid with a pair of interlaced missions. This mission by itself reoccupies a grid spaced at 10 km near the coast, widening to 20 km upstream. The two flights together establish a grid at half this spacing. We also refly a pair of 2012 lines over the Disko Island ice cap, and another 2016 line over the Nuussuaq Peninsula. For 2019 we replace ICESat-1 line 0419 with ICESat-2 line A0719 (beam 1L), which is occupied by the spacecraft on 15 May 2019.
