Not a cloud was seen today, Friday, our final day of the COAST mission. Take-off was at 10:38 to be on station for an 11:00 start to a four-hour and 50 minute flight. All indications are that the AATS, Headwall, and C-AIR instruments functioned properly for all 18 flight lines, coincident with measurements from Terra-MODIS, MERIS, the RV John Martin on the bay and from a small set of ground calibration sites. Everyone on the team was smiling!
