Days 171.0 to 177.0, 20-June to 26-June

Significant events at the ship during this period.

June 21 (172) - June 22 (173): 2300 to 0700 intercomparison with Sagres
June 24 (175), June 25 (176), June 27 (178), June 30 ( 181): Potential radiometric calibration of POLDER
June 25 (176): Clear Lagrangian with Sagres, ship, and C130 (but C130 did not pick up balloon signal

Meteorological Summary: A front moved through the region just north of the ACE-2 area on 21-22 June (Days 172-173). The 950 and 850mb back trajectories were from the west until 24 June, when they began arriving from over Spain and Portugal. Boundary Layer heights went from 600m on day 172 to 2700m on day 174 before lowering back to the 300 - 500m range on day 176.
