Daily Log

Besides the BROWN, the satellites, and the Airmap sites, there are thirteen different airplanes being used to collect air quality data for NEAQS. Several of these planes are currently flying out of Pease. Today, while the scientists and pilots were prepping the plane and the science instruments, I went on board the DC-3. The DC-3 is an airplane that is about 50 years old. The inside has been gutted and now there are just three seats, besides the two in the cockpit, and a LIDAR. The LIDAR is like the one that is on the BROWN but this one looks down, not up. It sends out a laser which can be used to determine the amount of ozone in the atmosphere below the plane. A large square hole, about 2 feet by two feet, has been cut through the bottom of the plane for the laser to shine down through and then for the light to bounce back into the instrument. The plane does not have a pressurized cabin so it is limited on how high it can fly. Most of the time during this flight, it will be at about 8000 ft. The DC-3 will also be flying slowly, about 100 miles per hour. This flight will take the crew and plane south and east and then out over the Atlantic, close to the BROWN.

This morning I talked to Fred . After we visited for a bit he recommended that I attend this afternoon’s planning meeting for tomorrow’s WP-3 flight. The meeting started at 5:30 with a brief discussion of the flight planned for tomorrow. Following that, in turn three of the scientists each explained to the rest of those attending the meeting what exactly each is studying and why. Remember the big elephant (from previous logs) that is being observed. Each scientist specializes on one very specific part of the pollution problem. To get a complete understanding of the problem all of these observations must be pieced together to a get a complete picture, which is the point of these science show and tells.
