The CU Airborne MAX-DOAS instrument was deployed in California aboard the NOAA Twin Otter research aircraft during May 19-July 19, 2010. A total of 52 flights were carried out covering the entire state but with a particular focus over South Coast Air Basin (SCAB) and the Sacramento area. CU AMAX-DOAS measured horizontal and vertical distributions of nitrogen dioxide (NO2), formaldehyde (HCHO) and glyoxal (CHOCHO) during the campaign. Other instruments aboard the aircraft included NOAA TOPAZ lidar which measures vertical profiles of ozone (O3) and aerosols, NCAS Doppler lidar which measures wind profiles, two radiometers to measure surface albedo, a radiometer to measure surface temperature, an in-situ O3 monitor and temperature sensors.
