The upcoming California AUAV Pollution Profiling project (CAPPS) will routinely monitor the vertical distribution of
aerosol and gas pollutants over California during 2008 using autonomous lightweight unmanned aircraft. The
measurements will be used to evaluate the impact of pollutants on California's climate, detect long range
transport, and to validate satellite measurements. Proven miniaturized instrumentation for collecting aerosol
parameters (concentration, size distribution, absorption), atmospheric solar radiation (flux, heating rates, albedo)
and meteorological parameters (thermodynamic structure, water vapor) that were flown during previous studies
will be deployed. Validation of these instruments is reviewed. New miniaturized instruments to collect the
concentration of gas species are being developed to compliment these established measurements. An ozone
monitor with a resolution of 2 ppb has been successfully integrated into the flight package. Results from the
laboratory validation of this instrument are presented. In addition, progress on a miniaturized carbon monoxide
sensor and NOx sensor are also presented.
